Granite is a type of igneous rock quarried for its extreme strength, density, durability, and resistance to corrosion. But granite is also very versatile– it's not just for squares and rectangles! Eqinisweni, sisebenza ngokuzethemba ngezakhi zamagogo ezidwetshiwe ngobunjwa, ama-angles, kanye nama-curve wazo zonke izehlakalo zokuhluka njalo - ngemiphumela emihle.
Ngesimo sethu sokucubungula ubuciko, ukusika kungasicaba kakhulu. Lezi zimfanelo zenza i-granite zibe yinto efanelekile ukudala usayizi wesiko kanye nezisekelo zomshini wezezifiso kanye nezinto ze-metrology. IGranite yile:
■ ngemayini
■ ifulethi elifanele lapho lisikiwe futhi liqediwe
■ Ukumelana nokugqwala
■ Ukuhlala isikhathi eside

Granite components are also easy to clean. Lapho udala ama-design ngokwezifiso, qiniseka ukuthi ukhetha uGranite ngezinzuzo zalo eziphakeme.

Izicelo / Izicelo Zokugqoka Eziphezulu
Ama-granite asetshenziswa yi-zhhimg ngemikhiqizo yethu yepuleti engaphezulu ye-vartz inokuqukethwe okuphezulu kwe-quartz, okunikezela ukumelana okukhulu ukugqoka nomonakalo. Imibala yethu emnyama ephakeme inamanani aphansi wokumuncwa kwamanzi, ukunciphisa amathuba okugqwala kwama-gauges akho anembile ngenkathi kuhlelwa emapuleti. Imibala ye-granite enikelwe yi-zhhimg iholela ekukhaleni okungaphansi, okusho ukuthi i-eyestrain engaphansi yabantu abasebenzisa amapuleti. Sikhethe izinhlobo zethu zama-granite ngenkathi sicubungula ukwanda okushisayo emzamweni wokugcina lesi sici esincane.

Izicelo Zokwezifiso
Lapho uhlelo lwakho lokusebenza lufuna ipuleti elinamajamo ngokwezifiso, ukufakwa okufakwe emculweni, ama-slots noma okunye mabhuku, uzofuna ukukhetha okufana neBlack JINAN BLACH. This natural material offers superior stiffness, excellent vibration dampening, and improved machinability.

It is important to note that color alone is not an indication of the physical qualities of the stone. Ngokuvamile, umbala kaGranite uhlobene ngokuqondile nokuba khona noma ukungabikho kwamaminerali, okungenzeka ukuthi akunakuthwala izimfanelo ezenza izinto ezinhle zepuleti. Kukhona ama-granutes apinki, ampunga, futhi amnyama alungele amapuleti angaphezulu, kanye nama-granutes amnyama, ampunga, futhi apinki angakulungele ngokuphelele izicelo zokunemba. Izici ezibucayi ze-granite, njengoba zibonisa ukusetshenziswa kwazo njengezinto ezibonakalayo zepuleti, azihlangene ngombala, futhi zinjengokulandelayo:
■ ukuqina (deflection ngaphansi komthwalo - kukhonjiswe yi-modulus of elasticity)


■ Ukuvimbela Ukumelana

■ Poiposi

We have tested many granite materials and compared these material. Finally we get the result, Jinan black granite is the best material we've ever know. I-Indian Black Granite kanye neGranite yaseNingizimu Afrika kufana ne-Jinan Black Granite, kepha izakhiwo zazo zenyama zingaphansi kwe-JINAN Black Granite. ZHHIMG will keep looking for more granite material in the world and compare their physical properties.

Ukukhuluma kabanzi nge-granite elungele iphrojekthi yakho, sicela uxhumane nathiinfo@zhhimg.com.

Abakhiqizi abahlukahlukene basebenzisa amazinga ahlukile. Kunamazinga amaningi emhlabeni.
I-Din Standard, ASME B89.3.7-2013 noma i-Federal Properication GGG-P-463C (amapuleti angaphezulu kwe-granite) nokunye

Isibonelo, ukubekezelelana kweflethi yamabanga amathathu ajwayelekile kuchazwa ekucacisweni kwe-Federal njengoba kunqunywe yifomula elandelayo:
■ Ibanga Laba Lakule Laboratoratri AA = (40 + Diagonal squared / 25) x .000001 "(Unilateral)
■ Ibanga lokuhlola A = Ibanga Laba Laborabula AA X 2
■ Igumbi lamathuluzi Ibanga B = Ibanga Laba Laborabula AA X 4.

Kumapuleti aphezulu asayizi asayizi, sikuqinisekisa ukubekezelela ukubekezelela okudlula izidingo zalolu ncazelo. Ngaphezu kokufutheka, i-ASME B89.3.7-2013 & Federal Propeisication GGG-P-463C Izihloko Zekheli, Ukuphinda Ukulinganisa, Indawo Yokuqina, Izindlela Zokuqina, Izindlela Zokuqina, Ukufakwa Kwezindlela Zokuhlola, njll.

Amapuleti angaphezulu kwe-Zhhimg Granite angaphezulu kanye namapuleti wokuhlola ama-granite noma adlule zonke izidingo ezibekwe kulokhu okucacisiwe. Njengamanje, akukho ukucaciswa okuchazayo kwamapuleti ama-granite angle, ukufana, noma izigcawu ze-master.

Futhi ungathola amafomula kwamanye amazinga ngaphakathiThwebula.

First, it is important to keep the plate clean. Uthuli olunomoya olwalumoya luvame ukuba ngumthombo omkhulu kakhulu wokugqoka nokudabula ipuleti, njengoba luvame ukushumeka izingcezu zomsebenzi kanye nezindawo zokuxhumana zamagagesi. Second, cover your plate to protect it from dust and damage. Ukugqoka impilo kunganwetshwa ngokumboza ipuleti lapho kungasebenzi, ngokujikeleza ipuleti ngezikhathi ezithile ukuze indawo eyodwa ingatholi ukusetshenziswa ngokweqile, nangokufaka amanye amaphakethe wensimbi eGauging ngama-carbide pads. Also, avoid setting food or soft drinks on the plate. Qaphela ukuthi iziphuzo eziningi ezithambile ziqukethe noma iyiphi i-carbonic noma i-phosphoric acid, ezingancibilikisa amaminerali athambile bese zishiya imigodi emincane ebusweni.

Lokhu kuncike ekutheni ipuleti liyasetshenziswa kanjani. Uma kungenzeka, sincoma ukuhlanza ipuleti ekuqaleni kosuku (noma ukushintshwa komsebenzi) futhi ekugcineni. Uma ipuleti lingcoliswa, ikakhulukazi uketshezi olunamafutha noma olunamathelayo, kufanele luhlanziwe ngokushesha.

The plate will also retain the water, and this could cause rusting of metal parts in contact with the surface. Ezinye izihlanza zizoshiya nezinsalela ezinamathelayo ngemuva kokusomile, okuzoheha uthuli lwezilwane, futhi empeleni zikhuphuke ukugqokwa, kunokuba zinciphe.

This depends on the plate usage and environment. We recommend that a new plate or precision granite accessory receive a full recalibration within one year of purchase. If the granite surface plate will see heavy use, it may be advisable to shorten this interval to six months. Ukuhlolwa kwanyanga zonke kwamaphutha wokulinganisa asebenzisa izinga le-elekthronikhi, noma idivaysi efanayo izokhombisa noma yiziphi izindawo ezithuthukayo futhi zithatha imizuzu embalwa okufanele ziyenze. Ngemuva kwemiphumela yokuphinda kwenziwe kabusha kunqunywe, isikhathi sokulinganisa singanwetshwa noma sifinyeze njengoba kuvunyelwe noma kudingeka uhlelo lwakho lwekhwalithi yangaphakathi.

Singanikeza insiza ukukusiza ukuhlola futhi ulinganise ipuleti lakho elingaphezulu le-granite.

Kunezimbangela eziningi ezingenzeka zokuhlukahluka phakathi kwezilinganiso:

• Ipuleti lisekelwa ngokungafanele
• Ukushintsha Kwezinga Lokushisa
• Okusalungiswa
• Ukuhlukahluka emazingeni okushisa mpo phakathi kobusika kanye nehlobo (uma kungenzeka, bazi ukushisa okumi mpo izingalo ngesikhathi kwenziwa.)
• Ipuleti alivumeli isikhathi esanele sokulungisa isimo ngemuva kokuthumela
• Ukusetshenziswa okungafanele kwemishini yokuhlola noma ukusetshenziswa kwemishini engalinganiselwe
• Ukushintshwa komhlaba okuvela ekugqokeni

Zingaki izinhlobo zezimbobo zokunemba uGranite?

For many factories, inspection rooms and laboratories, precision granite surface plates are relied on as the basis for accurate measurement. Ngoba konke ukukalwa okuqondile kuncike endaweni eyinkomba enembile lapho kuthathwa khona ubukhulu bokugcina, amapuleti angaphezulu ahlinzeka ngendiza engcono kakhulu yokuhlolwa komsebenzi kanye nesakhiwo ngaphambi kokuhlolwa kwemishini kanye nesakhiwo ngaphambi kokuhlolwa kwemishini. They also are ideal bases for making height measurements and gaging surfaces. Ngaphezu kwalokho, izinga eliphakeme lokufutheka, ukuqina, ikhwalithi ephelele kanye nokusebenza kwenza kube yisinqumo esihle sokufaka izinhlelo zokubamba izimboni ezinobuchwepheshe, ezenziwe ngogesi. For any of these measurement processes, it is imperative to keep surface plates calibrated.

Phinda izilinganiso kanye neflethi

Kokubili ukufutheka kanye nezilinganiso eziphindaphindwayo zibalulekile ukuqinisekisa ingaphezulu elinembile. I-Flatness ingabhekwa njengawo wonke amaphuzu ebusweni obuqukethwe ngaphakathi kwezindiza ezimbili ezihambisanayo, indiza eyisisekelo nendiza yophahla. The measurement of distance between the planes is the overall flatness of the surface. This flatness measurement commonly carries a tolerance and may include a grade designation.

Ukubekezelelana kweflethi amabanga amathathu ajwayelekile kuchazwa ekucacisweni kwe-Federal njengoba kunqunywe yifomula elandelayo:

I-Din Standard, GB Standard, ASME Standard, JJS standard, izwe elihlukile elinokuma okuhlukile ...

Imininingwane eminingi mayelana ne-Standard.

In addition to flatness, repeatability must be ensured. A repeat measurement is a measurement of local flatness areas. It is a measurement taken anywhere on the surface of a plate that will repeat within the stated tolerance. Ukulawula indawo yendawo yokubekezelelana ekubekezelelekeni okunzima kunendlela ephelele iqinisekisa ukuguqulwa kancane kancane kuphrofayela ye-survate flatness, ngaleyo ndlela kunciphise amaphutha endawo.

Ukuqinisekisa ukuthi ipuleti elingaphezulu lihlangabezana nokubumbana kanye nokuphindaphindeka kokulinganisa, abakhiqizi bamapuleti angaphezulu kwe-granite kufanele basebenzise i-Federal Surfate GGG-P-463C njengesisekelo sokucaciswa kwabo. Leli kheli elijwayelekile liphindaphinda ukunemba kokulinganisa, izindawo ezibonakalayo ze-granite yepuleti engaphezulu, ukuqeda okungaphezulu, indawo yokusekela, ukuqina, izindlela, izindlela ezamukelekayo zokuhlola nokufakwa kwezinto ezifakiwe.

Ihlola ukunemba kwepuleti

Ngaphambi kokuthi ipuleti elingaphezulu ligqoke okungaphezulu kokucaciswa kwethempeli eliphelele, lizokhombisa okuthunyelwe okugqokwa noma okuwayize. Ukuhlolwa kwanyanga zonke kwamaphutha wokulinganisa okuphindaphindiwe usebenzisa i-gage ephindaphindwayo kuzokhomba izindawo zokugqoka. I-gage ephindaphindwayo iyithuluzi elinembayo eliphakeme elithola iphutha lendawo futhi lingaboniswa ku-amplifier ephezulu ye-elekthronikhi.

Uhlelo lokuhlola olusebenzayo kufanele lufake amasheke ajwayelekile nge-autocollimator, ukuhlinzeka ngokulinganisa kwangempela kokutholwa okuphelele okulandelwayo ku-National Institute of Standard of Standard of Standard of Standard of Standard of Standards and Technology (NIST). Ukulinganisa okuphelele komkhiqizi noma inkampani ezimele iyadingeka ngezikhathi ezithile.

Ukuhluka phakathi kwezilinganiso

Kwezinye izimo, kunokuhlukahluka phakathi kokulinganiswa kwepuleti komhlaba. Kwesinye isikhathi izinto ezifana noshintsho lwangaphezulu oluvela ekugqokeni, ukusetshenziswa okungalungile kwemishini yokuhlola noma ukusetshenziswa kwemishini engavunyelwe kungalandisa ngalezi zinguquko. Lezi zinto ezimbili ezivame kakhulu, noma kunjalo, izinga lokushisa nokusekelwa.

One of the most important variables is temperature. For instance, the surface might have been washed with a hot or cold solution prior to calibration and not allowed sufficient time to normalize. Ezinye izimbangela zokushintsha izinga lokushisa zibandakanya okusalungiswa komoya obandayo noma oshisayo, ukukhanya kwelanga okuqondile, ukukhanyisa ngokweqile noma eminye imithombo yokushisa ekhazimulayo ebusweni bepuleti.

Amaphuzu amathathu kuphela angaphumula ngokuqinile kunoma yini ngaphandle kobuso obunembile. Ukuzama ukusekela ipuleti emaphoyinti angaphezu kwamathathu kuzodala ukuthi ipuleti lithole ukwesekwa kwalo kusuka kunhlanganisela ehlukahlukene yamaphoyinti amathathu, okungeke kube ngamaphuzu amathathu afanayo lapho esekelwa khona ngesikhathi sokukhiqiza. Lokhu kuzokwethula amaphutha njengoba ama-Plate anciphise ukuhambisana nelungiselelo elisha lokusekelwa. Cabanga ukusebenzisa imigwaqo yensimbi ngemishayo yokusekelwa eyenzelwe ukuhambisana namaphoyinti wokusekela afanele. Ukuma ngale njongo kutholakala ngokuvamile kumenzi wepuleti ongaphezulu.

Nweba impilo yepuleti

Okokuqala, kubalulekile ukugcina ipuleti lihlanzekile. Uthuli olunomoya olwalumoya luvame ukuba ngumthombo omkhulu kakhulu wokugqoka nokudabula epuletini, ngoba livame ukushumeka kwezindawo zokusebenza kanye nezindawo zokuxhumana zamaGauges.

Kubalulekile futhi ukumboza amapuleti ukuze uyivikele othulini nangomonakalo. Ukugqoka impilo kunganwetshwa ngokumboza ipuleti lapho kungasebenzi.

Gwema ukusetha ukudla noma iziphuzo ezithambile epuletini. Iziphuzo eziningi ezithambile ziqukethe i-carbonic noma i-phosphoric acid, ezingancibilikisa amaminerali athambile bese zishiya imigodi emincane ebusweni.

When a granite surface plate needs re-surfacing, consider whether to have this service performed on-site or at the calibration facility. It is always preferable to have the plate relapped at the factory or a dedicated facility. If, however, the plate is not too badly worn, generally within 0.001 inch of the required tolerance, it can be resurfaced on-site. Uma ipuleti ligqokwa kuze kube seqophelweni lapho ingaphezulu kuka-0.001 intshi ngaphandle kokubekezelelana, noma uma ifakwe kabi noma ihlawuliswe kabi, khona-ke kufanele ithunyelwe efektri ukuze igaye ngaphambi kokunciphisa.

Isikhungo sokulinganisa sinemishini yokuhlelwa kwemishini kanye nefekthri enikeza izimo ezinhle zokulinganisa amapuleti afanele kanye nokuhlelwa kabusha uma kunesidingo.

Great care should be exercised in selecting an on-site calibration and resurfacing technician. Cela ukuvunywa futhi uqinisekise imishini yokuthi uchwepheshe azowasebenzisa anokulinganisa okutholwe. Isipiliyoni futhi siyisici esibalulekile, njengoba kuthatha iminyaka eminingi ukuze ufunde ukuthi ungayilungisa kanjani ngokunemba i-granite.

Critical measurements start with a precision granite surface plate as a baseline. Ngokuqinisekisa ireferensi ethembekile ngokusebenzisa ipuleti elingaphezulu elilinganiselwe, abakhiqizi banelinye lamathuluzi abalulekile ezilinganiso ezithembekile nezingxenye ezingcono zekhwalithi.Q

Uhlu lokuhlola ukuhlukahluka kokulinganisa

Uthiphu

Yenza izilinganiso ezihlelekile okungenani kanye ngonyaka, yize amapuleti angaphezulu e-Granite abona ukusetshenziswa okunamandla kufanele kulinganiswe kaningi.

Ukulinganisa okusemthethweni, okurekhodiwe ezindaweni zokukhiqiza noma zokuhlola kuvame ukwenziwa ngokuqinisekiswa kwekhwalithi noma umthengisi wezinsizakalo zangaphandle, yize noma ngubani angasebenzisa igeji yokulinganisa ephindaphindayo ukuze ahlole ipuleti elingaphezulu ngaphambi kokuwasebenzisa.

Ngaphambi kweMpi Yezwe II, abakhiqizi basebenzise amapuleti angaphezulu kwensimbi ngokuhlolwa okuyisisekelo kwezingxenye. Ngesikhathi seMpi Yezwe II isidingo sensimbi sanda kakhulu, futhi kwancibilika amapuleti angaphezulu kwensimbi. A replacement was needed, and Granite became the material of choice because of its superior metrological properties.

Njengenothi eliseceleni, amanye amapuleti angaphezulu ensimbi asasebenza namuhla.

Izici zeMetrological zamapuleti ama-granite

Granite is an igneous rock formed by volcanic eruptions. Ngokuqhathanisa, imabula yi-metamorphosed limestone. Ukusetshenziswa kweMetrology, i-granite ekhethiwe kufanele ihlangabezane nezidingo ezithile ezichazwe ku-Federal Properification GGG-P-463C, kusukela manje ku-Fed Specs, futhi i-Granite, i-Granite kufanele ibe yinhle ekutholweni okumakiwe okuphakathi.

IGranite iyinto enzima, kepha ubulukhuni bawo buyehluka ngezizathu eziningana. Uchwepheshe weplanethi onolwazi angalinganisela ubulukhuni ngombala walo okuyisibonakaliso sokuqukethwe kwalo kwe-quartz. Ubulukhuni be-granite yindawo echazwe ngokwengxenye ngenani lokuqukethwe kwe-quartz nokuntuleka kwe-mica. Ama-granites abomvu apinki athambekele ekubeni nzima kunabo bonke, ama-gray alulukhuni oluphakathi, futhi abamnyama bathambile kakhulu.

Young's Modulus of Elasticity is used to express the flexibility or indication of the hardness of the stone. Pink granite averages 3-5 points on the scale, grays 5-7 points and blacks 7-10 points. The smaller the number, the harder the granite tends to be. The larger the number, the softer and more flexible granite is. Kubalulekile ukwazi ubunzima be-granite lapho ukhetha ubukhulu obudingekayo ukuze kubekezelelwe amamaki kanye nesisindo sezingxenye nama-gauges abekwe phezu kwawo.

Ezinsukwini zakudala lapho bekukhona imishini yangempela, eyaziwa ngezincwajana zabo zethebula le-trig emaphaketheni abo amahembe, i-granite emnyama yayithathwa njengeyi- "ihamba phambili." The Best defined as the type that gave the most resistance to wear or is harder. One drawback is that the harder granites tend to chip or ding easier. Machinists were so convinced that black granite was the best that some manufacturers of pink granite dyed them black.

Amabanga wepuleti angaphezulu komhlaba

P

Ukulinganisa kwe-Flatness ephelele (i-funness) kanye nokuphindaphindwa (ukugqoka okwenziwe kwasendaweni) kuwukuthi kumele ngokusho kwe-Fed Specs. Ukuphela kokungafani nalokhu kunamapuleti amancane lapho ukuphindwa khona kudingeka kuphela.

Futhi, futhi njengokugxeka okubucayi njengezinye izivivinyo, ukuhlolwa kwama-gradients ashisayo. (Bheka Delta T Ngezansi)

Umdwebo 1

Ukuhlolwa kweflatness kunezindlela ezi-4 ezivunyiwe. Amazinga kagesi, i-autocolliation, i-laser kanye nedivaysi eyaziwa ngokuthi yindawo yendiza. Sisebenzisa kuphela amazinga kagesi ngoba yindlela enembe futhi esheshayo kunazo zonke izizathu eziningana.

Lasers and autocollimators use a very straight beam of light as a reference. Umuntu wenza ukulinganiswa okuqondile kwepuleti elingaphezulu le-granite ngokuqhathanisa ukuhlukahluka ibanga phakathi kwepuleti elingaphezulu novalo lokukhanya. Ngokuthatha ugongolo oluqondile lokukhanya, lukushaya kulitshe lokubonisa ngenkathi kushukumisa ukumbozwa kwethafa phansi ipuleti elingaphezulu, ibanga phakathi kogongolo olukhishwe khona kanye nokubuyiselwa komhlaba kungokulinganisa okuqondile.

Here's the problem with this method. Ithagethi futhi umthombo uthinteka ngokudlidliza, izinga lokushisa elikhona, ngaphansi kwelitshe eliphansi noma elihlanjiwe, ukungcoliswa emoyeni, kanye ne-air Movement (ama-air Movement (ama-Air Movement (Currents). All these contribute additional components of error. Furthermore, the contribution of operator error from checks with an autocollimator is greater.

Umsebenzisi onolwazi we-autocollimator angenza izilinganiso ezinembile kakhulu kepha abhekene nezinkinga ngokuvumelana kokufundwa ikakhulukazi ngaphezulu kwamabanga amade njengoba kuboniswa ukunwebeka. Also, a less than perfectly flat target and a long day of peering through the lens produces additional errors.

A plane locator device is just silly. This device uses a somewhat straight (as compared to an extremely straight collimated or laser beam of light) as its reference. Hhayi nje ukuthi idivaysi yemishini isebenzisa inkomba ngokujwayelekile okuvame ukuthola ukulungiswa kwe-intshi engu-20 kuphela kodwa i-UN-iqonde yebha nezinto ezingekho emthethweni zengeza kakhulu emaphutheni. In our opinion, although the method is acceptable, no competent lab would ever use a plane locating device as a final inspection instrument.

Electronic levels use gravity as their reference. Differential electronic levels are not affected by vibration. Banesinqumo esiphansi njenge .1 I-ARC yesibili kanye nezilinganiso zishesha, zinembile futhi kunomnikelo omncane kakhulu wephutha ku-opharetha onolwazi. Neither Plane Locators nor autocollimators provide computer-generated topographical (Figure 1) or isometric plots (Figure 2) of the surface.

Umdwebo 2

Ifulethi elifanele lokuhlolwa komhlaba

A proper flatness of the surface test is such an important part of this paper I should have placed it at the beginning. As stated earlier, Fed Spec. GGG-p-463c IS NOT a calibration method. Kusebenza njengesiqondisi sezinto eziningi ze-Metrology Ibanga lamaGranite umthengi ohloswe ngalo noma iyiphi i-Federal Agency Agency, futhi lokho kufaka phakathi izindlela zokuhlola nokubekezelelana noma amamaki. If a contractor claims they adhered to Fed Specs, then the flatness value shall be determined by the Moody Method.

UMoody wayengumFunye ovela kuma-50's aqamba indlela yezibalo yokuthola ukuthi iflethi kanye ne-akhawunti yokuqagela kwemigqa ehlolwe, noma ngabe isondele ngokwanele endizeni efanayo. Akukho okushintshile. Isiginali esanele sizame ukuthuthuka ngendlela yezibalo kodwa saphetha ngokuthi umehluko ubesencane kakhulu bekungawufanele umzamo.

Indlela ye-Moody

Indlela ye-Moody yindlela yezibalo yokuthola ukuthi ngabe imigqa eyisishiyagalombili isendizeni efanayo. Ngaphandle kwalokho, unezintambo eziyi-8 eziqondile ezingase zibe noma zingatholakali noma zisondele endizeni efanayo. Ngaphezu kwalokho, usonkontileka othi ukunamathela ku-Fed Spec, futhi esebenzisa i-autocolliation, yena

Ngiyaqiniseka ukuthi ngabe ungomunye walabo abathola amapuleti akho alinganiswe usonkontileka esebenzisa i-autocollitation, awukaze ubabone lawo makhasi! Umdwebo 3 isampula yeeyodwa njeikhasi lesishiyagalombili elidingekayo ukufaka iflatheni eliphelele. Enye inkomba yalokho ukungazi kanye nobubi yilapho umbiko wakho unezinombolo ezinhle eziyindilinga. Isibonelo, ama-200, 400, 650, njll. Inani elihlanganisiwe liyinombolo yangempela. Isibonelo 325.4 ungena. Lapho usonkontileka esebenzisa indlela ye-Moody of Computions, kanti uchwepheshe ubala amanani ngesandla, kufanele wamukele amakhasi ayisishiyagalombili okuhlanganiswa nesakhiwo se-isometric. The isometric plot shows the varying heights along the different lines and how much distance separates the selected intersecting points.

Umdwebo 3(Kuthatha amakhasi ayisishiyagalombili afana nalokhu ukubala i-flatness ngesandla. Qiniseka ukuthi ubuza ukuthi kungani ungakutholi lokhu uma usonkontileka wakho esebenzisa i-autocolliation!)

Umdwebo 4

Ochwepheshe beGauge basebenzisa amazinga ahlukile (Umdwebo 4) Njengamadivaysi ancamelayo ukukala izinguquko zemizuzu ngokungezwani esiteshini sokulinganisa esiteshini. Amazinga anesinqumo esisezingeni eliphansi kuye .1 Ama-arc ama-arc (ama-intshi asebenzisa amasentimitha angu-4 asebenza kakhulu, awathinteki ngokudlidliza, amabanga alinganiswayo, amasondo omoya, ukukhathala komoya noma ezinye zezinkinga ezingokwemvelo. Ngeza usizo lwekhompyutha, futhi umsebenzi uba masinyane, ukukhiqiza amapulangwe aphezulu ne-isometric afakazela ukuqinisekiswa futhi okubaluleke kakhulu ukulungisa.

Usebenzisa inkomba yemishini ngesinqumo esingamasentimitha angama-20 kuphela awusizi ngalutho uma uzama ukuhlola isidingo esiphindaphindayo samasentimitha angama-35. Indicators have a 40 u Inches uncertainty! The repeat reading setup mimics a height gage/part configuration.

Umdwebo 5

Uma uvivinya ukuphindwaphindwa kwebhola eliyindilinga, khona-ke ukhombisile irediyo yebhola ayishintshile. (Iphrofayili ekahle yepuleti elilungiswe kahle inesimo esinomqhele we-convex.) Kodwa-ke, kusobala ukuthi ibhola alisicaba. Yebo, hlobo. Ebangeni elifushane kakhulu, liyisicaba. Njengoba iningi lomsebenzi wokuhlola libandakanya ukuphakama kwe-gage eduze kwengxenye, ukuphindaphinda kuba impahla ebaluleke kakhulu yepuleti elinamatshe. Kubaluleke kakhulu ukuthi iflethi eliphelele ngaphandle kokuthi umsebenzisi abheka ukuqondile kwengxenye ende.

Qiniseka ukuthi usonkontileka wakho wenza isivivinyo sokufunda esiphindaphindwayo. Ipuleti lingaba nokufundwa okuphindaphindiwe kakhulu ekubekezelelekeni kepha kusaphumelela ukuhlolwa kweflethi! Amazingly a lab can get accreditation in testing that does not include a repeat reading test. Ilebhu Engenakukwazi Ukulungisa noma ayilungile kakhulu ekulungiseni izilandi Flatness akuvamile ukuguquka ngaphandle kokuthi uhambise ipuleti.

Ukuphinda Ukuhlolwa kokufunda kulula kakhulu ukuhlola kepha okunzima kakhulu ukufeza lapho kukhala. Yenza okokoti kosonkontileka wakho angabuyisela ukuphindaphinda ngaphandle kokuthi "adubule" ingaphezulu noma ashiye amaza ebusweni.

Lokhu kuhlolwa kubandakanya ukukala lokushisa kwangempela kwetshe endaweni yalo ephezulu kanye nendawo yalo elingaphansi kanye ne-computer umehluko, i-Delta T, ukubika esitifiketini.

Kubalulekile ukwazi ukwakhiwa okuphakathi kokunwetshwa kwe-thermal eGranite ngu-3.5 Uin / inch / degree. Amazinga okushisa amient kanye nomphumela womswakama epuletini elinamafutha alinakwa. Kodwa-ke, ipuleti elingaphezulu lingaphuma ekubekezelelekeni noma kwesinye isikhathi lithuthukise noma ngabe ku-.3 - .5 degree f delta T. Kuyadingeka ukwazi ukuthi ngabe i-Delta T yalapho ingefani nokwehlukana khona kokugcina.

It is also important to know that a plates work surface migrates towards heat. If the top temperature is warmer than the bottom, then the top surface rises. If the bottom is warmer, which is rare, then the top surface sinks. Akwanele kwimenenja yekhwalithi noma uchwepheshe ukuze azi ipuleti liyisicaba futhi liphindeka ngesikhathi sokulinganisa noma ukulungisa kepha lokho kuyi-DELTA T yokuhlola ekugcineni. Ezimweni ezibucayi Umsebenzisi angakwazi, ngokulinganisa i-delta t uqobo, anqume ukuthi ngabe ipuleti liphume ekubekezeleleni ngenxa yokuhlukahluka kwe-delta t. Fortunately, granite takes many hours or even days to acclimate to an environment. Minor fluctuations in ambient temperature throughout the day will not effect it. For these reasons, we do not report ambient calibration temperature or humidity because the effects are negligible.

Granite Plate Wear

While granite is harder than steel plates, granite still develops low spots on the surface. Repetitive movement of parts and gages on the surface plate is the greatest source of wear, especially if the same area is constantly in use. Ukungcola nothuli lokugaya kuvunyelwe ukuhlala epuletani lepuleti kusheshisa inqubo yokugqoka njengoba kutholakala phakathi kwezingxenye noma ama-gauges kanye ne-granite. When moving parts and gages across its surface, abrasive dust is usually the cause of additional wear. I highly recommended constant cleaning to reduce wear. We have seen wear by on plates caused by daily UPS package deliveries placed on top of plates! Those localized areas of wear affect the calibration repeatability test readings. Avoid wear by cleaning regularly.

Ukuhlanza ipuleti ye-Granite

To keep the plate clean, use a tack cloth to remove grit. Just press very lightly, so you do not leave glue residue. A well-used tack cloth does an excellent job of picking up grinding dust between cleaning. Do not work in the same spot. Move your setup around the plate, distributing the wear. It is OK to use alcohol to clean a plate, but be aware that doing so will temporarily super cool the surface. Water with a small amount of soap is excellent. Izihlanza ezitholakala ngokuhweba ezinjenge-starrett's Cleaner nazo zihle kakhulu ukuzisebenzisa, kepha qiniseka ukuthi uthola zonke izinsalela zensipho ebusweni.

I-Granite Plate Report

Kufanele kubonakale manje ukubaluleka kokuqiniseka kosonkontileka bakho bepuleti engaphezulu kwenze ukulinganisa okunekhono. The “Clearing House” type labs that offer “Do it all with one call” programs rarely have a technician that can do repairs. Noma benikeza ukulungiswa, abahlali babe nochwepheshe ohlale enesipiliyoni esidingekayo lapho ipuleti elingaphezulu liphuze kakhulu ekubekezeleni.

Our techs work a one to one and a half year apprenticeship under a Master Surface Plate Technician. Sichaza ubuchwepheshe bepuleti ye-master super njengomuntu ophothule ukufundela umsebenzi futhi unesipiliyoni seminyaka eyishumi eyengeziwe ekulinganisweni kwepuleti engaphezulu kokulungiswa. We at Dimensional Gauge have three Master Technicians on staff with over 60 years experience combined. One of our Master Technician is available at all times for support and guidance for when difficult situations arise. Bonke ochwepheshe bethu banolwazi ekulinganiseni kwamapuleti komhlaba wonke osayizi, kusuka ezimweni ezincane kuya kwezikhulu kakhulu, ezahlukahlukene zemvelo, izimboni ezihlukile, nezinkinga ezinkulu zokugqoka.

Lapho silungisa sihlola ipuleti ukuze likhule kahle kanye neleveli. Sisebenzisa indlela eyomile yokukhangisa, kepha ezimweni zokugqoka okwedlulele okudinga ukususwa okukhulu kwama-granite, simanzi. Ochwepheshe bethu bazihlanza balandela, baphelele, bashesha futhi bayaqondile. Lokho kubalulekile ngoba izindleko ze-Granite Plate Service zifaka isikhathi sakho sokuphumula futhi zilahlekelwe ukukhiqizwa. Ukulungiswa okufanelekile kubaluleke kakhulu, futhi akufanele ukhethe usonkontileka ngentengo noma lula. Eminye imisebenzi yokulinganisa ifuna abantu abaqeqeshwe kakhulu. Sinakho lokho.

1. Usayizi ku-ft. (X 'x x')

1. Umbala
3. I-modulus elinganisiwe ye-elasticity
5. Phinda ukubekezelela ukufunda (kunqunywe ubude be-diagonal kuma-inches)
6. Kusho indiza njengoba itholakele
7. Kusho indiza njengoba kwesokunxele
8. Phinda ufunda njengoba kutholakele
9. Phinda ufunde njengoba kwesokunxele

Uma uchwepheshe edinga ukwenza i-lingling noma ukulungiswa komsebenzi epuletini elingaphezulu, khona-ke isitifiketi sokulinganisa sihambisana nesakhiwo se-topographical noma i-isometric ukufakazela ukulungiswa okuvumelekile.

Ngoba nje ilebhu inesivumo sokuvunyelwa kokulinganisa kwepuleti engabonakali akusho ukuthi bayazi ukuthi benzani okuncane kakhulu ukukwenza kahle! Futhi akusho nje ukuthi ilebhu likwazi ukulungisa. Imizimba evumayo ayiwenzi umehluko phakathi kokuqinisekiswa noma ukulungiswa (ukulungisa).A2izidumbu ezigunyazayoLbophaAribbon around my dog if I paid them enough money! It is a sad fact. I have seen labs get accreditation by performing only one of the three tests required. Ngaphezu kwalokho, ngibonile ama-labs athola ukuqinisekiswa ngokungaqiniseki okungenangqondo futhi agunyazwe ngaphandle kobufakazi noma umbukiso wokuthi babala kanjani amanani. It is all unfortunate.

Awukwazi ukubukela phansi indima yokunemba amapuleti ama-granite. Isethenjwa esicwebezelayo esinikezwa amapuleti ama-granite yisisekelo lapho wenza khona zonke ezinye izilinganiso.

Ungasebenzisa amathuluzi wokulinganisa anamuhla, anembe kakhulu futhi ahlukahlukene kakhulu. Kodwa-ke, izilinganiso ezinembile kunzima ukuthola ukuthi ingaphezulu kwereferensi alizicaba. Ngesinye isikhathi, ngaba nekhasimende elizobe ngithi kimi "kahle kumane nje!" Impendulo yami, "Kulungile, ulungile, futhi nakanjani awukwazi ukuthethelela ukuthi ochwepheshe bangene ukuze balondoloze amapuleti akho angaphezulu."

Intengo ayisona isizathu esihle sokukhetha osonkontileka bepuleti elingaphezulu. Abathengi, ama-accountants kanye nenombolo ephazamisayo yonjiniyela bekhwalithi abaqondi ngaso sonke isikhathi ukuthi ukuhlanganisa kabusha amapuleti akufani ne-micrometer, i-caliper noma i-DMM.

Ezinye izinsimbi zidinga ubuchwepheshe, hhayi intengo ephansi. Ngemuva kokusho lokho, amanani ethu anengqondo kakhulu. Ikakhulu yokuqiniseka ukuthi senza umsebenzi kahle. Sihamba kahle ngaphesheya kwezidingo ze-ISO-17025 ne-Federal Specification ngenani elingeziwe.

Isisekelo se-Precisite Granite singathuthukisa ukusebenza kwamathuluzi womshini

Izidingo zihlala zikhuphuka ngobunjiniyela bemishini bebonke kanye nokwakhiwa kwamathuluzi womshini ikakhulukazi. Ukuthola ukunemba okuphezulu namanani wokusebenza ngaphandle kwezindleko ezandayo zinzima zinzima zokuncintisana. Umbhede wamathuluzi womshini uyinto enqumayo lapha. Ngakho-ke, abakhiqizi bamathuluzi amaningi ngokwengeziwe nabaningi bancike eGranite. Ngenxa yamapharamitha alo ngokomzimba, inikeza izinzuzo ezicacile ezingenakutholwa ngokhonkolo wensimbi noma ye-polymer.

I-Granite yi-volutionanic deep rock futhi inesakhiwo esiminyene kakhulu futhi enobunzima obukhulu kakhulu bokunwebeka, okuvuselelwa okuphansi okushisayo kanye nokudla okuphezulu okuphezulu.

Ngezansi uzothola ukuthi kungani umbono ojwayelekile wokuthi i-Granite ilungele kuphela njengoba isisekelo somshini sokuhlanganisa imishini yokulinganisa isikhathi eside siphelelwe isikhathi futhi kungani lelo thuluzi lomshini njengethuluzi lomshini omkhulu ngisho nakumathuluzi womshini onobuhle obukhulu.

Singenza izingxenye ze-granite zokunyakaza okunamandla, izingxenye ze-granite zama-motors aqondile, izingxenye ze-granite ze-NDT, izingxenye ze-cnc, izingxenye ze-granite ze-aerospace, izingxenye ze-granite ze-aerosse

Inani eliphakeme eliphakeme ngaphandle kwezindleko ezingezekile
Ukusetshenziswa okukhulayo kwe-granite kunjiniyela wemishini akukubi kangako ngenxa yokwanda okukhulu kwentengo yensimbi. Esikhundleni salokho, kungenxa yokuthi inani elingeziwe lethuluzi lomshini elitholwe ngombhede womshini owenziwe ngogogo kungenzeka ngezindleko ezincane kakhulu noma azikho. Lokhu kufakazelwa ngokuqhathanisa izindleko zabakhiqizi bethuluzi lomshini owaziwayo eJalimane naseYurophu.

Inzuzo enkulu ekuqineni kwe-thermodynamic, ukudliwa kwe-vibled nokunemba isikhathi eside okwenziwe nge-granite akunakutholwa ngensimbi ephonsane noma embhedeni wensimbi, noma kuphela ngezindleko eziphakeme. Isibonelo, amaphutha we-thermal angalandisa kuze kufike ku-75% wephutha eliphelele lomshini, ngesinxephezelo ngokuvamile azame nge-software - ngempumelelo elinganiselayo. Ngenxa yokuvuka kwayo okuphansi okuphansi, i-granite yisisekelo esingcono sokunemba isikhathi eside.

Ngokubekezelelana kwe-1 μm, i-granite ihlangabezana kalula nezidingo zamafulethi ngokusho kwe-DIN 876 ngezinga lokunemba 00. Ngenani le-6 ku-Hardness Scale 1 kuya ku-2,8g / cm³ licishe lifinyelele inani le-aluminium. Lokhu kubuye kubuye nezinzuzo ezingezekile ezinjengamanani aphezulu okuphakelayo, ukushesha kwe-axis ephezulu kanye nokwandiswa kwempilo yamathuluzi yamathuluzi omshini wokusika. Ngakho-ke, ushintsho olusuka embhedeni we-cast embhedeni we-granite luhamba ithuluzi lomshini okukhulunywa ngalo kwisigaba esiphakeme kakhulu ngokuya ngokunemba nokusebenza - ngaphandle kwezindleko ezengeziwe.

I-Granite's Ecological's Ecological Foolic

Futhi akukho zintukuthelo zezinsizakusebenza zeGranite. It is a deep rock formed from magma within the earth's crust. 'Ivuthiwe' ngezigidi zeminyaka futhi itholakala ngobuningi obukhulu njengomthombo wemvelo cishe kuwo wonke amazwekazi, kufaka phakathi wonke ama-Europe.

Isiphetho: Izinzuzo eziningi ezikhohlisayo ze-granite ziqhathaniswa nensimbi noma i-iron yensimbi zivumela ukuzimisela okwandayo konjiniyela bemishini ukusebenzisa le ngozi yemvelo njengesisekelo sokunemba okuphezulu, okuphezulu kwemishini yemishini. Imininingwane enemininingwane mayelana nezakhiwo ze-granite, ezizuzisa amathuluzi omshini kanye nobunjiniyela bemishini, kungatholakala kule ndatshana.

A repeat measurement is a measurement of local flatness areas. The Repeat Measurement specification states that a measurement taken anywhere on the surface of a plate will repeat within the stated tolerance. Ukulawula indawo yendawo yendawo ethambile kune-Flatness ephelele iqinisekisa ushintsho kancane kancane kuphrofayili ye-survate Flatness

Iningi labakhiqizi, kufaka phakathi izinhlobo zamangeniso, banamathela ekucacisweni kwe-Federal of the Flatness Revances kodwa abaningi abangakunaki izilinganiso eziphindaphindwayo. Many of the low value or budget plates available in the market today will not guarantee repeat measurements. Umkhiqizi ongakuqinisekisi ukuphindaphinda ukuthi akhiqizi amapuleti ahlangabezana nezidingo ze-ASME B89.3.7-2013 noma i-Federal Properication GGG-P-463C, noma i-DIN 876, GB, JJS ...

Both are critical to ensure a precision surface for accurate measurements. Flatness specification alone is not sufficient to guarantee measurement accuracy. Thatha njengesibonelo, ibanga lokuhlola elingu-36 x 48 linye kuphela, elihlangabezana nokucaciswa kweflethi kuphela .000300 " Actually, it can be much higher if the gage is resting on the slope of an incline.

Amaphutha we-.000600 "-. 000800" kungenzeka, kuya ngobunzima bomthambeka, futhi ubude be-gage busetshenziswa. Uma leli puleti linokucaciswa okuphindaphindwayo okucacisiwe kwe-.000050 " Enye inkinga, evame ukuvela lapho uchwepheshe ongafundile ezama ukuwela kabusha ipuleti esizeni, ukusetshenziswa kwezilinganiso eziphindaphindwayo zodwa ukufaka ipuleti.

Izinsimbi ezisetshenziselwa ukuqinisekisa ukuphindaphinda azikhelwe ukubheka iflethi lonke. Uma isethwe ku-zero endaweni egobekile kahle, bazoqhubeka nokufunda zero, ukuthi leyo ndawo iyisicaba noma i-concave ephelele noma i-convex 1/2 "!

Yes, but they can only be guaranteed for a specific vertical temperature gradient. Imiphumela yokunwetshwa kwe-thermal epuletini ingadala kalula ushintsho ngokunemba kunokubekezelela uma kukhona ushintsho ku-gradient. Kwezinye izimo, uma ukubekezelelana kuqinile ngokwanele, ukushisa okumunca kusuka ekukhanyiseni okuphezulu kungadala ngokwanele koshintsho olungaphezulu kwamahora ambalwa.

I-Granite ine-coefficied yokwanda okushisayo okucishe kube yi-inches nge-intshi ngayinye nge-1 ° F. Njengesibonelo: Ipuleti elingaphezulu le-36 "x 48" linokunemba kwe-.000075 "(1/2 yeBanga Aa) endaweni engu-0 ° F, phezulu nangaphansi kungamazinga okushisa afanayo. Uma phezulu kwepuleti kufudumeza kuze kube seqophelweni lapho kungu-1 ° F kufudumele kunaphansi, ukunemba kungashintsha ku-.000275 "I-Convex.

Ipuleti elingaphezulu kufanele lisekelwe ngamaphuzu ama-3, litholakala kahle ngo-20% wobude obuvela emaphethelweni epuleti. Izisekelo ezimbili kufanele zitholakale ama-20% wobubanzi obusezinhlangothini ezinde, futhi ukusekelwa okusele kufanele kugxilwe. Amaphuzu ama-3 kuphela angaphumula ngokuqinile kunoma yini ngaphandle kobuso obunembile.

The plate should be supported at these points during production, and it should be supported only at these three points while in use. Ukuzama ukusekela ipuleti emaphoyinti angaphezu kwamathathu kuzodala ukuthi ipuleti lithole ukwesekwa kwalo kusuka kunhlanganisela ehlukahlukene yamaphoyinti amathathu, okungeke kube ngamaphoyinti ama-3 afanayo lapho esekelwa khona ngesikhathi sokukhiqiza. This will introduce errors as the plate deflects to conform to the new support arrangement. All zhhimg steel stands have support beams designed to line up with the proper support points.

Uma ipuleti selisekelwa kahle, izinga eliqondile liyadingeka kuphela uma uhlelo lwakho lokusebenza luwudinga. Ukulinganisa akudingekile ukugcina ukunemba kwepuleti elisekelwe kahle.

Izisekelo Zomshinina-Izingxenye zeMetrology?

The answer is 'yes' for almost every application. Izinzuzo ze-granite zifaka phakathi: akukho ukugqwala noma ukugqwala, kucishe kungavikelekile ekungeneni, kungabikho ukunxephezela i-hump lapho kuncibilikisa impilo, ngokunemba okungekho magnetic, ukusebenziseka okuphansi, izindleko zokulungiswa okuphansi.

Granite is a type of igneous rock quarried for its extreme strength, density, durability, and resistance to corrosion. But granite is also very versatile– it's not just for squares and rectangles! Eqinisweni, iStarrett Tru-Stone ngokuqiniseka isebenza ngokuzethemba ngezakhi zamagogo ezidwetshiwe ngobunjwa, ama-engeli, kanye nama-curve wazo zonke izinhlobo zokuhlukahluka.

Ngesimo sethu sokucubungula ubuciko, ukusika kungasicaba kakhulu. Lezi zimfanelo zenza i-granite zibe yinto efanelekile ukudala usayizi wesiko kanye nezisekelo zomshini wezezifiso kanye nezinto ze-metrology. IGranite yile:

isicaba ngokunembile uma usikiwe futhi uqediwe
Ukugqwala kokuqina
-qinile

Izakhi ze-Granite nazo zilula ukuzihlanza. Lapho udala ama-design ngokwezifiso, qiniseka ukuthi ukhetha uGranite ngezinzuzo zalo eziphakeme.

Amazinga/ Izicelo Zokugqoka Eziphezulu
Ama-Granite asetshenziswa yi-Zhonghui ngemikhiqizo yethu yepuleti engaphezulu ye-quartz inokuqukethwe okuphezulu kwe-quartz, okunikeza ukumelana okukhulu ukugqoka nomonakalo. Imibala yethu ephakeme ephakeme emnyama futhi ekhanyayo inamanani aphansi okufakwa kwamanzi, inciphisa amathuba okugqwala kwakho okuqondile ngenkathi uhleli emapuleti. The colors of granite offered by ZhongHui result in less glare, which means less eyestrain for individuals using the plates. We have chosen our granite types while considering thermal expansion in an effort to keep this aspect minimal.

Izicelo Zokwezifiso
Lapho uhlelo lwakho lokusebenza lufuna ipuleti elinamajamo ngokwezifiso, ukufakwa okufakwe emculweni, ama-slots noma okunye mabhuku, uzofuna ukukhetha okufana ne-Black Diachay. Lokhu kusetshenziswa kwemvelo kunikeza ukuqina okuphezulu, ukudlidliza okuhle kakhulu okudayisayo, kanye nokukhononda okuthuthukile.

Yes, if they are not too badly worn. Our factory setting and equipment allow the optimum conditions for proper plate calibration and rework if necessary.

Ipuleti, umthwalo lapho wehlulekile kwakungu-12,990 lbs. https://www.zhhimg.com/standard-thread-inserts-product/

Yes, but only at our factory. At our plant, we can restore almost any plate to 'like-new' condition, usually for less than half the cost of replacing it. Damaged edges can be cosmetically patched, deep grooves, nicks, and pits can be ground out, and the attached supports can be replaced. Ngaphezu kwalokho, singaguqula ipuleti lakho ukuze likhulise ukuguquguquka kwalo ngokungeza ukufakwa kwensimbi okuqinile noma okuhlanganisiwe kanye nokusika ama-slots noma izindebe zakho.

Kungani ukhethe uGranite?

Ngezisekelo zomshini kanye nezakhi zeMetrology, i-granite emnyama ingumbala osetshenziswa kakhulu. I-Black Granite inephesenti eliphakeme le-quartz kuneminye imibala futhi, ngakho-ke, ukugqokwa okunzima kakhulu.

I-Granite iyabiza kakhulu, futhi ukusika kungavuthwa okuyingqayizivele. Akukhona kuphela ukuthi kungabanjwa ngesandla ukufeza ukweqisa okweqisayo, kepha ukuphinda kuphindiselo kungenziwa ngaphandle kokuhambisa ipuleti noma itafula elivaliwe. Kuyinto ngokuphelele ukusebenza ngesandla futhi ngokuvamile kubiza okungaphansi kokuphinda kufakwe kabusha isimo se-cast yensimbi.

Lezi zimfanelo zenza i-granite i-granite ebaluleke kakhulu ukudala usayizi wezezimali kanye nezisekelo zomshini wezezifiso kanye nezingxenye zeMetrology ezifana neipuleti elingaphezulu kwe-granite.

I-Zhonghui ikhiqiza imikhiqizo ye-bespoke granite eyenzelwe ukusekela izidingo ezithile zokulinganisa. Lezi zinto ze-bespoke ziyehlukahluka kuyeImiphetho eqondile toIzikwele ze-TRI. Ngenxa yemvelo eguquguqukayo ye-granite, theizingxenye

Izinzuzo zamapuleti angaphezulu kwe-granite
Ukubaluleka kokulinganisa endaweni engaphezulu kwasungulwa nguMsunguli waseBrithani uHenry Maudsley ngeminyaka yama-1800. Njengethuluzi lomshini, wanquma ukuthi ukukhiqizwa okungaguquki kwezingxenye kudinga indawo eqinile yezilinganiso ezithembekile.

Inguquko yezimboni idala isidingo sokulinganisa indawo, ngakho-ke inkampani yezobunjiniyela iCrown Windley idale amazinga okukhiqiza. Izindinganiso zamapuleti angaphezulu kwaqala kusethwe khona ngomqhele ngo-1904 usebenzisa insimbi. Njengoba isidingo nezindleko zensimbi zanda, ezinye izinto zendawo yokulinganisa ziyaphenywa.

EMelika, uMdali weMonument Wallace Herman wasungula ukuthi i-Black Granite yayiyindlela enhle kakhulu yepuleti yeplate yensimbi. Njengoba i-granite ingeyona in-magthetic futhi ayigqwayi, ngokushesha kwaba yindawo yokulinganisa ethandwayo.

Ipuleti elingaphezulu le-granite liwukutshalwa kwemali okubalulekile kwelebhu kanye nezindawo zokuhlola. Ipuleti elingaphezulu le-granite lama-600 x 600 mm lifakwe endaweni yokusekelwa. Izindawo zinikeza ukuphakama okusebenzayo kwama-34 "(0.86m) ngamaphoyinti amahlanu aguqukayo wokulinganisa.

Ngemiphumela yokulinganisa ethembekile futhi engaguquki, ipuleti elingaphezulu le-granite libalulekile. Njengoba ingaphezulu liyindiza ebushelelezi nelizinzile, inika amandla amathuluzi ukuze akhohliswe ngokucophelela.

Izinzuzo eziphambili zamapuleti angaphezulu kwe-granite yilezi:

• Akubonisi
• Ukumelana namakhemikhali nokugqwala
• I-coefficient ephansi yokwanda uma kuqhathaniswa ne-cart iron ethinteke kangako ngoshintsho lokushisa
• ngokwemvelo eqinile futhi egqoke kanzima


• I-non-magnetic
• Kulula ukuhlanza nokugcina

• Ilungele ukumba kokufakwa kokusekelwa okufakwe
• Ukudonswa okuphezulu okuphezulu

Ezitolo eziningi, amakamelo okuhlola kanye nama-laboratories, ukucacisa amapuleti angaphezulu kwe-granite granite ancike njengesisekelo sokulinganisa okunembile. Ngoba konke ukukalwa okuqondile kuncike endaweni eyinkomba enembile lapho kuthathwa khona ubukhulu bokugcina, amapuleti angaphezulu ahlinzeka ngendiza engcono kakhulu yokuhlolwa komsebenzi kanye nesakhiwo ngaphambi kokuhlolwa kwemishini kanye nesakhiwo ngaphambi kokuhlolwa kwemishini. Futhi ziyizisekelo ezinhle zokwenza izilinganiso zokuphakama kanye nezindawo zokudla. Ngaphezu kwalokho, izinga eliphakeme lokufutheka, ukuqina, ikhwalithi ephelele kanye nokusebenza kwenza kube yisinqumo esihle sokufaka izinhlelo zokubamba izimboni ezinobuchwepheshe, ezenziwe ngogesi. For any of these measurement processes, it is imperative to keep surface plates calibrated.

Phinda izilinganiso kanye neflethi
Kokubili ukufutheka kanye nezilinganiso eziphindaphindwayo zibalulekile ukuqinisekisa ingaphezulu elinembile. I-Flatness ingabhekwa njengawo wonke amaphuzu ebusweni obuqukethwe ngaphakathi kwezindiza ezimbili ezihambisanayo, indiza eyisisekelo nendiza yophahla. Ukulinganiswa kwebanga phakathi kwezindiza kuyinto ephelele yobuso. Lesi silinganiso sokufutheka sivame ukubekezelelana futhi singafaka ukubizwa kwebanga.

Ukubekezelelana kweflethi amabanga amathathu ajwayelekile kuchazwa ekucacisweni kwe-Federal njengoba kunqunywe yifomula elandelayo:

Ibanga Lokuhlola A = Ibanga Laba Laboratori AA X 2
Igumbi lamathuluzi Ibanga B = Ibanga Laba Laborabula AA x 4

In addition to flatness, repeatability must be ensured. A repeat measurement is a measurement of local flatness areas. It is a measurement taken anywhere on the surface of a plate that will repeat within the stated tolerance. Ukulawula indawo yendawo yokubekezelelana ekubekezelelekeni okunzima kunendlela ephelele iqinisekisa ukuguqulwa kancane kancane kuphrofayela ye-survate flatness, ngaleyo ndlela kunciphise amaphutha endawo.

Ukuqinisekisa ukuthi ipuleti elingaphezulu lihlangabezana nokubumbana kanye nokuphindaphindeka kokulinganisa, abakhiqizi bamapuleti angaphezulu kwe-granite kufanele basebenzise i-Federal Surfate GGG-P-463C njengesisekelo sokucaciswa kwabo. Leli kheli elijwayelekile liphindaphinda ukunemba kokulinganisa, izindawo ezibonakalayo ze-granites yepuleti elingaphezulu, ukuqeda okungaphezulu, indawo yokusekela, ukuqina, izindlela, izindlela ezamukelekayo zokuhlola nokufakwa kwezinto ezifakiwe.

Ngaphambi kokuthi ipuleti elingaphezulu ligqoke okungaphezulu kokucaciswa kwethempeli eliphelele, lizokhombisa okuthunyelwe okugqokwa noma okuwayize. Ukuhlolwa kwanyanga zonke kwamaphutha wokulinganisa okuphindaphindiwe usebenzisa i-gage ephindaphindwayo kuzokhomba izindawo zokugqoka. I-gage ephindaphindwayo iyithuluzi elinembayo eliphakeme elithola iphutha lendawo futhi lingaboniswa ku-amplifier ephezulu ye-elekthronikhi.

Ihlola ukunemba kwepuleti
Ngokulandela izinkombandlela ezimbalwa ezilula, ukutshalwa kwezimali epuletini elingaphezulu le-granite kufanele kuhlale iminyaka eminingi. Ngokuya kokusetshenziswa kwepuleti, imvelo yesitolo kanye nokunemba okudingekayo, imvamisa yokubheka ukunemba kwepuleti ingahlukahluka kuye. Umthetho ojwayelekile wesithupha wepuleti elisha ukuthola ukuphindisela okugcwele kungakapheli unyaka owodwa wokuthenga. Uma ipuleti lisetshenziswa kaningi, kungakuhle ukuthi kufinyeze lesi sikhathi esiyizinyanga eziyisithupha.

Ngaphambi kokuthi ipuleti elingaphezulu ligqoke okungaphezulu kokucaciswa kwethempeli eliphelele, lizokhombisa okuthunyelwe okugqokwa noma okuwayize. Ukuhlolwa kwanyanga zonke kwamaphutha wokulinganisa okuphindaphindiwe usebenzisa i-gage ephindaphindwayo kuzokhomba izindawo zokugqoka. I-gage ephindaphindwayo iyithuluzi elinembayo eliphakeme elithola iphutha lendawo futhi lingaboniswa ku-amplifier ephezulu ye-elekthronikhi.

Uhlelo lokuhlola olusebenzayo kufanele lufake amasheke ajwayelekile nge-autocollimator, ukuhlinzeka ngokulinganisa kwangempela kokutholwa okuphelele okulandelwayo ku-National Institute of Standard of Standard of Standard of Standard of Standard of Standards and Technology (NIST). Ukulinganisa okuphelele komkhiqizi noma inkampani ezimele iyadingeka ngezikhathi ezithile.

Ukuhluka phakathi kwezilinganiso
Kwezinye izimo, kunokuhlukahluka phakathi kokulinganiswa kwepuleti komhlaba. Kwesinye isikhathi izinto ezifana noshintsho lwangaphezulu oluvela ekugqokeni, ukusetshenziswa okungalungile kwemishini yokuhlola noma ukusetshenziswa kwemishini engavunyelwe kungalandisa ngalezi zinguquko. Lezi zinto ezimbili ezivame kakhulu, noma kunjalo, izinga lokushisa nokusekelwa.

One of the most important variables is temperature. For instance, the surface might have been washed with a hot or cold solution prior to calibration and not allowed sufficient time to normalize. Ezinye izimbangela zokushintsha izinga lokushisa zibandakanya okusalungiswa komoya obandayo noma oshisayo, ukukhanya kwelanga okuqondile, ukukhanyisa ngokweqile noma eminye imithombo yokushisa ekhazimulayo ebusweni bepuleti.

Amaphuzu amathathu kuphela angaphumula ngokuqinile kunoma yini ngaphandle kobuso obunembile. Ukuzama ukusekela ipuleti emaphoyinti angaphezu kwamathathu kuzodala ukuthi ipuleti lithole ukwesekwa kwalo kusuka kunhlanganisela ehlukahlukene yamaphoyinti amathathu, okungeke kube ngamaphuzu amathathu afanayo lapho esekelwa khona ngesikhathi sokukhiqiza. Lokhu kuzokwethula amaphutha njengoba ama-Plate anciphise ukuhambisana nelungiselelo elisha lokusekelwa. Cabanga ukusebenzisa imigwaqo yensimbi ngemishayo yokusekelwa eyenzelwe ukuhambisana namaphoyinti wokusekela afanele. Ukuma ngale njongo kutholakala ngokuvamile kumenzi wepuleti ongaphezulu.

Kubalulekile ukugcina ipuleti lihlanzekile. Uthuli olunomoya olwalumoya luvame ukuba ngumthombo omkhulu kakhulu wokugqoka futhi uklebhule epuletini, ngoba livame ukushumeka kwezindawo zokusebenza kanye nezindawo zokuxhumana zamageji. Mboza amapuleti ukuze ubavikele othulini nangomonakalo. Wear life can be extended by covering the plate when not in use.

Nweba impilo yepuleti
Ukulandela imihlahlandlela embalwa kuzonciphisa ukugqoka epuletini elingaphezulu kwe-granite futhi ekugcineni, kwandise impilo yaso.

Okokuqala, kubalulekile ukugcina ipuleti lihlanzekile. Uthuli olunomoya olwalumoya luvame ukuba ngumthombo omkhulu kakhulu wokugqoka futhi uklebhule epuletini, ngoba livame ukushumeka kwezindawo zokusebenza kanye nezindawo zokuxhumana zamageji.

Kubalulekile futhi ukumboza amapuleti ukuze uyivikele othulini nangomonakalo. Ukugqoka impilo kunganwetshwa ngokumboza ipuleti lapho kungasebenzi.

Gwema ukusetha ukudla noma iziphuzo ezithambile epuletini. Iziphuzo eziningi ezithambile ziqukethe i-carbonic noma i-phosphoric acid, ezingancibilikisa amaminerali athambile bese zishiya imigodi emincane ebusweni.

When a granite surface plate needs re-surfacing, consider whether to have this service performed on-site or at the calibration facility. It is always preferable to have the plate relapped at the factory or a dedicated facility. If, however, the plate is not too badly worn, generally within 0.001 inch of the required tolerance, it can be resurfaced on-site. Uma ipuleti ligqokwa kuze kube seqophelweni lapho ingaphezulu kuka-0.001 intshi ngaphandle kokubekezelelana, noma uma ifakwe kabi noma ihlawuliswe kabi, khona-ke kufanele ithunyelwe efektri ukuze igaye ngaphambi kokunciphisa.

Isikhungo sokulinganisa sinemishini yokuhlelwa kwemishini kanye nefekthri enikeza izimo ezinhle zokulinganisa amapuleti afanele kanye nokuhlelwa kabusha uma kunesidingo.

Ukunakekelwa okukhulu kufanele kusetshenziswe ekukhetheni uchwepheshe wokulinganisa esizeni kanye nokuvuselela uchwepheshe. Cela ukugunyazwa futhi uqinisekise imishini yokuthi uchwepheshe azowasebenzisa anokulinganisa okunamahloni. Isipiliyoni futhi siyisici esibalulekile, njengoba kuthatha iminyaka eminingi ukuze ufunde ukuthi ungayilungisa kanjani ngokunemba i-granite.

Critical measurements start with a precision granite surface plate as a baseline. Ngokuqinisekisa ireferensi ethembekile ngokusebenzisa ipuleti elingaphezulu elilinganiselwe, abakhiqizi banelinye lamathuluzi abalulekile ezilinganiso ezithembekile nezingxenye ezingcono zekhwalithi.

Uhlu lokuhlola ukuhlukahluka kokulinganisa

1. Ingaphezulu laligezwa ngesisombululo esishisayo noma esibandayo ngaphambi kokulinganisa futhi asivunyelwe isikhathi esanele sokwenza okujwayelekile.
