I-Granite iwuhlobo lwetshe elivuthayo elimbiwa amandla alo eqisayo, ukuminyana, ukuqina, nokumelana nokugqwala.Kodwa i-granite ibuye ibe nezinto ezihlukahlukene kakhulu– ayiyona nje eyezikwele nonxande!Eqinisweni, Sisebenza ngokuzethemba ngezingxenye zegwadle ezakhiwe ngomumo, ama-engeli, namajika akho konke ukuhlukahluka njalo—ngemiphumela emihle kakhulu.
Ngokucutshungulwa kwesimo sethu sobuciko, izindawo ezisikiwe zingaba zicaba ngendlela ehlukile.Lezi zimfanelo zenza i-granite ibe into efanelekile yokwakha usayizi wangokwezifiso nezisekelo zemishini eklanywe ngokwezifiso kanye nezingxenye ze-metrology.I-Granite yilokhu:
■ kuyasebenziseka
■ isicaba lapho isikiwe futhi isiqediwe
■ ukumelana nokugqwala
■ isikhathi eside
■ ihlala isikhathi eside
Izingxenye ze-Granite nazo kulula ukuzihlanza.Lapho udala imiklamo yangokwezifiso, qiniseka ukuthi ukhetha i-granite ngezinzuzo zayo eziphezulu.

AMAZINGA / IZICELO ZOKUGQOKA OKUPHEZULU
I-granite esetshenziswa yi-ZHHIMG emikhiqizweni yethu evamile yepuleti langaphezulu inokuqukethwe okuphezulu kwe-quartz, okunikeza ukumelana okukhulu nokuguga nokulimala.Imibala yethu Emnyama Ephakeme inamazinga aphansi okumunca amanzi, enciphisa amathuba okuthi amageji akho anembe agle ngenkathi usetha kumapuleti.Imibala yegwadle ehlinzekwa yi-ZHHIMG iphumela ekubenyeni okuncane, okusho ukuthi ukucindezelwa kwamehlo kuyancipha kubantu abasebenzisa amapuleti.Sikhethe izinhlobo zethu zegwadle ngenkathi sicabangela ukunwetshwa kokushisa emzamweni wokugcina lesi sici sincane.

IZICELO ZOKUFANELEKILE
Uma uhlelo lwakho lokusebenza ludinga ipuleti elinomumo ngokwezifiso, okufakwayo okuluchungechunge, izikhala noma okunye ukukhanda, uzofuna ukukhetha into efana ne-Black Jinan Black.Le nto yemvelo inikezela ngokuqina okuphezulu, ukudambisa ukudlidliza okuhle kakhulu, nokusebenza okuthuthukisiwe.

Kubalulekile ukuqaphela ukuthi umbala wodwa awuyona inkomba yezimfanelo ezibonakalayo zetshe.Ngokuvamile, umbala we-granite uhlobene ngokuqondile nokuba khona noma ukungabi khona kwamaminerali, okungenzeka kungabi nalutho ezimfanelweni ezenza izinto ezinhle zamapuleti angaphezulu.Kukhona ama-granite aphinki, ampunga, namnyama ahamba kahle kakhulu kumapuleti angaphezulu, kanye nama-granite amnyama, ampunga, naphinki angafaneleki ngokuphelele ukusetshenziswa okunembayo.Izici ezibalulekile ze-granite, njengoba ziphathelene nokusetshenziswa kwayo njenge-surface plate material, azihlangene nombala, futhi zimi kanje:
■ Ukuqina (ukuchezuka ngaphansi komthwalo - kuboniswa yi-Modulus of Elasticity)
■ Ubulukhuni
■ Ukuminyana
■ Ukumelana nokugqoka
■ Ukuzinza
■ I-Porosity

Sihlole izinto eziningi ze-granite futhi saqhathanisa lezi zinto.Ekugcineni sithola umphumela, i-Jinan black granite iyimpahla engcono kakhulu esake sayazi.Igwadule elimnyama laseNdiya kanye negwadle laseNingizimu Afrika ziyafana neJinan Black Granite, kodwa izakhiwo zazo ezibonakalayo zingaphansi kweJinan Black Granite.I-ZHHIMG izoqhubeka nokubheka izinto eziningi ze-granite emhlabeni futhi iqhathanise izakhiwo zayo ezibonakalayo.

Abakhiqizi abahlukene basebenzisa amazinga ahlukene.Kunamazinga amaningi emhlabeni.
I-DIN Standard, ASME B89.3.7-2013 noma Federal Specification GGG-P-463c (Granite Surface Plates) nokunye njengesisekelo sokucaciswa kwazo.

Futhi singakwazi ukwenza ipuleti lokuhlola ukunemba kwe-granite ngokwezidingo zakho.Siyakwamukela ukuthintana nathi uma ufuna ukwazi ulwazi olwengeziwe mayelana namazinga amaningi.

I-flatness ingabhekwa njengawo wonke amaphuzu angaphezulu aqukethwe ngaphakathi kwezindiza ezimbili ezifanayo, indiza eyisisekelo kanye nendiza yophahla.Isilinganiso sebanga phakathi kwezindiza wukucaba kwendawo yonke.Lesi silinganiso sokucaba sivame ukubekezelela futhi singabandakanya ukuqokwa kwebanga.

Isibonelo, ukubekezelelwa kokucaba kwamabanga amathathu ajwayelekile kuchazwa ekucacisweni kombuso njengoba kunqunywa ifomula elandelayo:
■ Ibanga Laselabhorethri AA = (40 + diagonal squared/25) x .000001" (uhlangothi olulodwa)
■ IBanga Lokuhlola A = IBanga Laselabhorethri AA x 2
■ Igumbi Lamathuluzi IBanga B = IBanga Laselabhorethri AA x 4.

Kumapuleti angaphezulu anosayizi obujwayelekile, siqinisekisa ukubekezelela ukucaba okudlula izimfuneko zalokhu kucaciswa.Ngaphezu kokucaba, i-ASME B89.3.7-2013 & Federal Specification GGG-P-463c izihloko zamakheli ezihlanganisa: ukunemba kokulinganisa okuphindaphindayo, izakhiwo ezibonakalayo zamatshe amapuleti angaphezulu, ukuphela kwendawo, indawo yokusekela, ukuqina, izindlela ezamukelekayo zokuhlola, ukufakwa okufakwe imicu, njll.

Amapuleti angaphezulu egwadle e-ZHHIMG namapuleti okuhlola egwadle ahlangabezana noma adlule zonke izimfuneko ezibalulwe kulokhu kucaciswa.Okwamanje, akukho ukucaciswa okuchazayo kwamapuleti e-engeli egwadule, ama-parallel, noma izikwele eziyinhloko.

Futhi ungathola amafomula amanye amazinga kuLANDA.

Okokuqala, kubalulekile ukugcina ipuleti lihlanzekile.Uthuli oluqhunyiswa emoyeni ngokuvamile luwumthombo omkhulu kakhulu wokuguga nokudabuka epuletini, njengoba luvamise ukushumeka ezicucu zokusebenza nasezindaweni zokuthintana zamageji.Okwesibili, vala ipuleti lakho ukuze ulivikele othulini nasekulimaleni.Impilo yokugqoka inganwetshwa ngokumboza ipuleti lapho lingasetshenziswa, ngokuzungezisa ipuleti ngezikhathi ezithile ukuze indawo eyodwa ingatholi ukusetshenziswa ngokweqile, nangokushintsha amaphedi okuxhumana ensimbi kugeji ngamaphedi e-carbide.Futhi, gwema ukubeka ukudla noma iziphuzo ezibandayo epuletini.Qaphela ukuthi iziphuzo ezibandayo eziningi ziqukethe i-carbonic noma i-phosphoric acid, engancibilikisa amaminerali athambile futhi ishiye imigodi emincane phezulu.

Lokhu kuncike ekutheni ipuleti lisetshenziswa kanjani.Uma kungenzeka, sincoma ukuhlanza ipuleti ekuqaleni kosuku (noma ishifu yomsebenzi) futhi futhi ekugcineni.Uma ipuleti lingcoliswa, ikakhulukazi uketshezi olunamafutha noma olunamathelayo, kufanele lihlanzwe ngokushesha.

Hlanza ipuleti njalo ngoketshezi noma i-ZHHIMG yokuhlanza amapuleti angenamanzi.Ukukhethwa kwezixazululo zokuhlanza kubalulekile.Uma kusetshenziswa i-solvent eguquguqukayo (i-acetone, i-lacquer thinner, utshwala, njll.) ukuhwamuka kuzopholisa phezulu, futhi kuphazamise.Kulokhu, kuyadingeka ukuvumela ipuleti ukuthi lijwayele ngaphambi kokulisebenzisa noma amaphutha okulinganisa azokwenzeka.

Isikhathi esidingekayo ukuze ipuleti lizinze lizohluka ngosayizi wepuleti, kanye nenani lokupholisa.Ihora kufanele lanele amapuleti amancane.Kungase kudingeke amahora amabili amapuleti amakhulu.Uma kusetshenziswa okokuhlanza okusekelwe emanzini, kuzoba khona nokuhwamuka okuthile.

Ipuleti lizophinda ligcine amanzi, futhi lokhu kungase kubangele ukugqwala kwezingxenye zensimbi ezithintana nendawo engaphezulu.Abanye abahlanzi bazophinde bashiye insalela enamathelayo ngemva kokoma, okuzoheha uthuli oluphuma emoyeni, futhi empeleni kukhulise ukuguga, kunokuba kunciphise.

Lokhu kuncike ekusetshenzisweni kwepuleti nendawo ezungezile.Sincoma ukuthi ipuleti elisha noma insiza ye-granite enembile ithole ukulinganiswa kabusha okugcwele phakathi nonyaka owodwa wokuthenga.Uma i-granite surface plate izobona ukusetshenziswa okunzima, kungase kube ukuhlakanipha ukufinyeza lesi sikhawu sibe izinyanga eziyisithupha.Ukuhlolwa kwanyanga zonke kwamaphutha okulinganisa okuphindayo kusetshenziswa ileveli ye-elekthronikhi, noma idivayisi efanayo izobonisa noma yiziphi izindawo zokuguga ezikhulayo futhi kuthatha imizuzu embalwa kuphela ukwenza.Ngemuva kokuthi imiphumela yokulinganiswa kabusha kokuqala isinqunyiwe, isikhawu sokulinganisa singanwetshwa noma sifinyezwe njengoba kuvunyelwe noma kudingwa isistimu yakho yekhwalithi yangaphakathi.

Singakunikeza isevisi ukukusiza ukuthi uhlole futhi ulinganise ipuleti lakho elingaphezulu legwadle.

Kunezizathu eziningana ezingabangela ukuhluka phakathi kokulinganisa:

• Indawo yayigezwa ngesisombululo esishisayo noma esibandayo ngaphambi kokulinganisa, futhi yayingavunyelwe isikhathi esanele sokujwayela.
• Ipuleti alisekelwa ngendlela engafanele
• Ukushintsha kwezinga lokushisa
• Okusalungiswa
• Ukukhanya kwelanga okuqondile noma okunye ukushisa okukhazimulayo ebusweni bepuleti.Qiniseka ukuthi ukukhanyisa phezulu akushisi indawo
• Ukwehluka kwezinga lokushisa elime mpo phakathi kobusika nehlobo (Uma kungenzeka, yazi izinga lokushisa elime mpo ngesikhathi ukulinganisa kwenziwa.)
• Ipuleti alivunyelwe isikhathi esanele sokujwayela ngemuva kokuthunyelwa
• Ukusetshenziswa okungalungile kwempahla yokuhlola noma ukusetshenziswa kwezinto ezingakaliwe
• Ukushintsha kobuso ngenxa yokuguga

Zingaki izinhlobo zemigodi kugwadule olunembayo ?

Izikhala ku-Precision Granite Components

Emafekthri amaningi, amagumbi okuhlola namalabhorethri, amapuleti angaphezulu egwadle okunembayo kuthenjelwe kuwo njengesisekelo sokulinganisa okunembile.Ngenxa yokuthi zonke izilinganiso zomugqa zincike endaweni eyinkomba enembile lapho kuthathwa khona ubukhulu bokugcina, amapuleti angaphezulu ahlinzeka ngendiza eyinkomba engcono kakhulu yokuhlolwa komsebenzi kanye nesakhiwo ngaphambi komshini.Futhi ayizisekelo ezikahle zokwenza izilinganiso zobude kanye nezindawo zokugawula.Ngaphezu kwalokho, izinga eliphezulu lokusicaba, ukuzinza, ikhwalithi iyonke kanye nokusebenza kahle kubenza babe yisinqumo esihle sokukhweza amasistimu egeji emishini eyinkimbinkimbi, e-electronic kanye ne-optical.Kunoma iyiphi yalezi zinqubo zokulinganisa, kubalulekile ukugcina amapuleti angaphezulu elinganiselwe.

Phinda Izilinganiso kanye Flatness

Kokubili ukucaba nokuphindaphinda izilinganiso kubalulekile ukuze kuqinisekiswe indawo enembayo.I-flatness ingabhekwa njengawo wonke amaphuzu angaphezulu aqukethwe ngaphakathi kwezindiza ezimbili ezifanayo, indiza eyisisekelo kanye nendiza yophahla.Isilinganiso sebanga phakathi kwezindiza wukucaba kwendawo yonke.Lesi silinganiso sokucaba sivame ukubekezelela futhi singabandakanya ukuqokwa kwebanga.

Ukubekezelela ukucabana kwamabanga amathathu ajwayelekile kuchazwa ekucacisweni kombuso njengoba kunqunywa ifomula elandelayo:

I-DIN Standard, i-GB Standard, i-ASME Standard, i-JJS ejwayelekile... izwe elihlukile elinesitendi esihlukile...

Imininingwane eyengeziwe mayelana ne-standard.

Ngaphezu kokuqina, ukuphindaphinda kufanele kuqinisekiswe.Ukulinganisa okuphindayo ukukalwa kwezindawo eziphansi zendawo.Kuyisilinganiso esithathwa noma yikuphi phezu kwepuleti elizophinda ngaphakathi kokubekezelelana okushiwo.Ukulawula ukucaba kwendawo ukuze kube nokubekezelelana okuqinile kunokucaba sekukonke kuqinisekisa ushintsho kancane kancane kuphrofayela yokucaba kwendawo, ngaleyo ndlela kuncishiswe amaphutha endawo.

Ukuqinisekisa ukuthi ipuleti elingaphezulu lihlangabezana nakho kokubili ukucaba nokucaciswa kokulinganisa okuphindayo, abakhiqizi bamapuleti angaphezulu kwegwadle kufanele basebenzise i-Federal Specification GGG-P-463c njengesisekelo sokucaciswa kwabo.Leli zinga likhuluma ngokunemba kokulinganisa okuphindaphindwayo, izakhiwo zezinto ezibonakalayo ze-surface plate granite, isiphetho esingaphezulu, indawo yephoyinti lokusekela, ukuqina, izindlela ezamukelekayo zokuhlola nokufakwa kwezinto ezifakiwe ezinentambo.

Ihlola Ukunemba Kwepuleti

Ngokulandela iziqondiso ezimbalwa ezilula, ukutshalwa kwezimali ku-granite surface plate kufanele kuhlale iminyaka eminingi.Ngokuya ngokusetshenziswa kwepuleti, indawo yesitolo nokunemba okudingekayo, imvamisa yokuhlola ukunemba kwepuleti elingaphezulu liyahlukahluka.Umthetho ojwayelekile owokuthi ipuleti elisha lithole ukulinganiswa kabusha okugcwele phakathi nonyaka owodwa wokuthenga.Uma ipuleti lisetshenziswa njalo, kuyatuseka ukuthi lesi sikhawu sifinyezwe sibe yizinyanga eziyisithupha.

Ngaphambi kokuthi ipuleti elingaphezulu ligqokwe ngaphezu kokucaciswa kokucaba okuphelele, lizobonisa izigxobo ezigugile noma ezinamagagasi.Ukuhlolwa kwanyanga zonke kwamaphutha okulinganisa okuphinda kusetshenziswa igeji yokufunda ephindayo kuzokhomba izindawo ezigugile.Igaji yokufunda ephindayo iyithuluzi elinemba okuphezulu elithola iphutha lasendaweni futhi lingaboniswa kusikhulisi se-electronic magnification high.

Uhlelo lokuhlola olusebenzayo kufanele lubandakanye ukuhlola okuvamile nge-autocollimator, okuhlinzeka ngokulinganiswa kwangempela kokucaba okuphelele okulandelekayo ku-National Institute of Standards and Technology (NIST).Ukulinganisa okuphelele komkhiqizi noma inkampani ezimele kuyadingeka ngezikhathi ezithile.

Izinguquko Phakathi Kwezilinganiso

Kwezinye izimo, kukhona ukuhluka phakathi kokulinganisa kwamapuleti angaphezulu.Kwesinye isikhathi izinto ezinjengokushintsha kwendawo okubangelwa ukuguga, ukusetshenziswa okungalungile kwempahla yokuhlola noma ukusetshenziswa kwezinto ezingalinganiselwe zingabalela lokhu kuhlukahluka.Nokho, izici ezimbili ezivame kakhulu izinga lokushisa nokusekela.

Enye yezinto eziguquguqukayo ezibaluleke kakhulu izinga lokushisa.Isibonelo, indawo engaphezulu kungenzeka ukuthi igezwe ngesisombululo esishisayo noma esibandayo ngaphambi kokulinganisa futhi akuvunyelwe isikhathi esanele sokujwayela.Ezinye izimbangela zokushintsha kwezinga lokushisa zihlanganisa okusalungiswa komoya obandayo noma oshisayo, ukukhanya kwelanga, ukukhanya okungaphezulu noma eminye imithombo yokushisa okukhazimulayo ebusweni bepuleti.

Kungase futhi kube nokuhluka kwezinga lokushisa eliqondile phakathi kobusika nehlobo.Kwezinye izimo, ipuleti alivunyelwe isikhathi esanele sokujwayela ngemva kokuthunyelwa.Kungumqondo omuhle ukurekhoda izinga lokushisa elime mpo ngesikhathi ukulinganisa kwenziwa.

Esinye isizathu esivamile sokuhlukahluka kokulinganisa ipuleti elingasekelwa ngokungafanele.Ipuleti elingaphezulu kufanele lisekelwe emaphuzwini amathathu, abekwe ngokufanelekile angama-20% ubude ukusuka ekugcineni kwepuleti.Izisekelo ezimbili kufanele zibekwe ku-20% wobubanzi phakathi ukusuka ezinhlangothini ezinde, futhi ukusekelwa okusele kufanele kugxile.

Amaphuzu amathathu kuphela angahlala aqinile kunoma yini ngaphandle kwendawo enembayo.Ukuzama ukusekela ipuleti ngamaphuzu angaphezu kwamathathu kuzokwenza ukuthi ipuleti lithole ukwesekwa kwalo ezinhlanganisela ezihlukahlukene zamaphuzu amathathu, okungeke kube amaphuzu amathathu afanayo lapho lisekelwa khona ngesikhathi sokukhiqiza.Lokhu kuzokwethula amaphutha njengoba ipuleti lichezuka ukuze lihambisane nokuhlelwa okusha kosekelo.Cabangela ukusebenzisa izitendi zensimbi ezinemishayo yokusekela eklanyelwe ukuhambisana namaphoyinti afanele okusekela.Izitendi zale njongo zivame ukutholakala kumkhiqizi wamapuleti angaphezulu.

Uma ipuleti lisekelwa kahle, ukulinganisa okunembile kuyadingeka kuphela uma isicelo sikucacisa.Ukulinganisa akudingekile ukuze kugcinwe ukunemba kwepuleti elisekelwe kahle.

Nweba Impilo YePlate

Ukulandela imihlahlandlela embalwa kuzonciphisa ukuguga kwepuleti le-granite elingaphezulu futhi ekugcineni, kunwebe impilo yalo.

Okokuqala, kubalulekile ukugcina ipuleti lihlanzekile.Uthuli oluqhunyiswa emoyeni ngokuvamile luwumthombo omkhulu kakhulu wokuguga nokudabuka epuletini, njengoba luvamise ukushumeka ezintweni zokusebenza nasezindaweni zokuthintana zamageji.

Kubalulekile futhi ukumboza amapuleti ukuze uvikeleke othulini nasekulimaleni.Impilo yokugqoka inganwetshwa ngokumboza ipuleti uma lingasetshenziswa.

Zungezisa ipuleti ngezikhathi ezithile ukuze indawo eyodwa ingatholi ukusetshenziswa ngokweqile.Futhi, kunconywa ukuthi kuthathelwe indawo amaphedi okuxhumana ensimbi ku-gauging ngamaphedi e-carbide.

Gwema ukubeka ukudla noma iziphuzo ezibandayo epuletini.Iziphuzo ezibandayo eziningi zine-carbonic noma i-phosphoric acid, engancibilikisa amaminerali athambile futhi ishiye imigodi emincane phezulu.

Lapho Ozobuyela Khona

Uma ipuleti elingaphezulu kwegwadle lidinga ukuphinde libekwe phezulu, cabanga ukuthi le sevisi yenziwe endaweni noma endaweni yokulinganisa.Kuhlale kuncono ukuthi ipuleti liphinde libuyele embonini noma endaweni ezinikele.Kodwa-ke, uma ipuleti lingagqokile kabi kakhulu, ngokuvamile phakathi kweyintshi engu-0.001 yokubekezelelana okudingekayo, lingaphinde livulwe esizeni.Uma ipuleti ligqokwe lifike endaweni lapho lingaphezu kuka-0.001 intshi ngenxa yokubekezelelana, noma uma libhodlozwe kabi noma lifakwe i-nicked, kufanele lithunyelwe efekthri ukuze ligaywe ngaphambi kokuphinda liphindwe.

Indawo yokulinganisa inemishini kanye nesethingi yefekthri ehlinzeka ngezimo ezikahle zokulinganiswa kwepuleti okufanele nokusebenza kabusha uma kunesidingo.

Kufanele kuqashelwe kakhulu ekukhetheni uchwepheshe osebenza endaweni yokulinganisa nokufaka kabusha izulu.Cela ukugunyazwa futhi uqinisekise ukuthi okokusebenza okuzosetshenziswa uchwepheshe kunokulinganiswa okulandelekayo.Okuhlangenwe nakho nakho kuyisici esibalulekile, njengoba kuthatha iminyaka eminingi ukufunda indlela yokuhlanganisa ngokunembile igwadle.

Izilinganiso ezibucayi ziqala ngepuleti eliphezulu legwadle elinembayo njengesisekelo.Ngokuqinisekisa ireferensi ethembekile ngokusebenzisa ipuleti langaphezulu elilinganiswe kahle, abakhiqizi banethuluzi elilodwa elibalulekile lokulinganisa okuthembekile nezingxenye zekhwalithi engcono.Q

Yebo, uma zingagqokile kakhulu.Ukusethwa kwefekthri yethu nokokusebenza kuvumela izimo ezikahle zokulinganiswa kwepuleti okufanele nokusebenza kabusha uma kunesidingo.Ngokuvamile, uma ipuleti lingaphakathi kuka-.001" wokubekezelela okudingekile, lingabuye livulwe endaweni. Uma ipuleti ligqokwe lifike endaweni lapho lingaphezu kuka-.001" ngenxa yokubekezelelwa, noma uma liboshwe kabi noma i-nicked, khona-ke izodinga ukuthunyelwa efektri ukuze igaywe ngaphambi kokuphindaphinda.

Kufanele kuqashelwe kakhulu ekukhetheni uchwepheshe osebenza endaweni yokulinganisa nokufaka kabusha izulu.Sikunxusa ukuthi usebenzise ukuqaphela ekukhetheni isevisi yakho yokulinganisa.Cela ukugunyazwa futhi uqinisekise impahla ezosetshenziswa uchwepheshe inokulinganisa okulandelekayo kweNational Inspection Institution.Kuthatha iminyaka eminingi ukufunda indlela yokugoqa ngokunemba i-granite.

I-ZhongHui ihlinzeka ngokushintsha ngokushesha ekulinganiseni okwenziwe efekthri yethu.Thumela amapuleti akho ukuze alinganiswe uma kungenzeka.Ikhwalithi nesithunzi sakho sincike ekunembeni kwamathuluzi akho okulinganisa okuhlanganisa namapuleti angaphezulu!

Amapuleti ethu angaphezulu amnyama anokuqina okuphezulu kakhulu futhi aqinile ngokuphindwe kathathu.Ngakho-ke, ipuleti elenziwe ngokumnyama alidingi ukuthi libe likhulu njengepuleti le-granite elinosayizi ofanayo ukuze libe nokumelana okulinganayo noma okukhulu ekuphambukeni.Ukuqina okuncishisiwe kusho isisindo esincane kanye nezindleko eziphansi zokuthutha.

Qaphela abanye abasebenzisa igwadle elimnyama elisezingeni eliphansi ngobukhulu obufanayo.Njengoba kushiwo ngenhla, izakhiwo zegwadle, njengokhuni noma insimbi, ziyahlukahluka ngokomsebenzi nombala, futhi akusona isibikezelo esinembile sokuqina, ukuqina, noma ukumelana nokugqoka.Eqinisweni, izinhlobo eziningi ze-granite emnyama ne-diabase zithambile kakhulu futhi azifanele ukusetshenziswa kwepuleti elingaphezulu.

Cha. Imishini ekhethekile nokuqeqeshwa okudingekayo ukuze kusetshenzwe kabusha lezi zinto kudinga ukuba zibuyiselwe efektri ukuze zilungiswe futhi zisetshenzwe kabusha.

Yebo.I-Ceramic ne-granite inezici ezifanayo, futhi izindlela ezisetshenziselwa ukulinganisa kanye ne-lap granite zingasetshenziswa nezinto zobumba.I-Ceramics inzima kakhulu ukugoqa kune-granite okuholela ezindlekweni eziphezulu.

Yebo, inqobo nje uma okufakiwe kumiswe phansi ngezansi.Uma izinsimbi zensimbi zishaywa, noma ngaphezu kwendiza engaphezulu, kufanele zibheke phansi ngaphambi kokuba ipuleti ligqitshwe.Uma kudingeka, singanikeza leyo sevisi.

Yebo.Ukufakwa kwensimbi okunochungechunge olufunekayo (isiNgisi noma imethrikhi) kungenziwa i-epoxy eboshwe epuletini ezindaweni ezifunwayo.I-ZhongHui isebenzisa imishini ye-CNC ukuze inikeze izindawo eziqinile zokufaka phakathi kuka-+/- 0.005”.Okufakwayo okungabalulekile kangako, ukubekezelela kwethu kwasendaweni kokufaka okunentambo kungu-±.060". Ezinye izinketho zihlanganisa ama-T-Bars ensimbi kanye nezikhala ze-dovetail ezifakwe ngqo kugwadule.

Okufakiwe okuboshelwe kahle kusetshenziswa i-epoxy yamandla aphezulu nomsebenzi omuhle kuzomelana namandla amaningi okugubha nokugunda.Ocwaningweni lwakamuva, kusetshenziswa okufakwe imicu engu-3/8"-16, ilabhorethri yokuhlola ezimele ilinganise amandla adingekayo ukuze kudonswe into efakwe i-epoxy-bonded esuka epuletini elingaphezulu. Kuhlolwe amapuleti ayishumi. Kulezi eziyishumi, ezimweni eziyisishiyagalolunye, i Igwadule laphuka kuqala. Isilinganiso somthwalo endaweni yokuhluleka sasingu-10,020 lbs kugwadule olumpunga kanye no-12,310 lbs kokumnyama. Esimeni esisodwa lapho okufakiwe kukhishwe ngaphandle kwepuleti, umthwalo endaweni yokwehluleka wawungu-12,990 lbs. Uma ucezu lomsebenzi lwakha ibhuloho eliwela okokufaka bese kusetshenziswa i-torque eyeqisayo, kungenzeka ukukhiqiza amandla anele ukuphuka igwadle. Ngokwengxenye yalesi sizathu, u-ZhongHui unikeza imihlahlandlela yetorque ephezulu ephephile engasetshenziswa ukufakwa kwe-epoxy bonded. : https://www.zhhimg.com/standard-thread-inserts-product/

Yebo, kodwa embonini yethu kuphela.Embonini yethu, singakwazi ukubuyisela cishe noma yiliphi ipuleti esimweni 'esifana nelisha', ngokuvamile ngemali engaphansi kwengxenye yezindleko zokulishintsha.Imiphetho eyonakele ingalungiswa ngendlela yobuhle, imisele ejulile, ama-nick, kanye nemigodi kungasuswa, futhi izisekelo ezinamathiselwe zingashintshwa.Ngaphezu kwalokho, singashintsha ipuleti lakho ukuze sandise ukuguquguquka kwalo ngokwengeza izinsimbi eziqinile noma ezinemicu kanye nezikhala zokusika noma izindebe ezibambayo, ngokwezicaciso zakho.

Kungani Khetha I-Granite?
I-Granite uhlobo lwamatshe avuthayo akhiwa emhlabeni eminyakeni eyizigidi edlule.Ukwakheka kwe-igneous rock kwakuqukethe amaminerali amaningi njenge-quartz eqinile kakhulu futhi engagugi.Ngaphezu kokuqina nokuqina kwe-granite yokumelana nokuqina cishe inengxenye ye-coefficient yokunwetshwa njenge-cast iron.Njengoba isisindo sayo se-volumetric cishe siyingxenye eyodwa kwezintathu yensimbi ecijile, i-granite kulula ukuyilawula.

Ezisekelweni zemishini nezingxenye ze-metrology, igwadle elimnyama umbala osetshenziswa kakhulu.I-granite emnyama inephesenti eliphezulu le-quartz kuneminye imibala futhi, ngakho-ke, ukugqoka okunzima kakhulu.

I-Granite iyonga kakhulu, futhi izindawo ezisikiwe zingaba flat ngendlela ehlukile.Akukona nje kuphela ukugoqwa ngesandla ukuze kuzuzwe ukunemba okwedlulele, kodwa ukulungisa kabusha kungenziwa ngaphandle kokususa ipuleti noma itafula ngaphandle kwesayithi.Kuwumsebenzi wokuzungeza isandla ngokuphelele futhi ngokuvamile kubiza kancane kakhulu kunokulungisa enye indlela yensimbi ekhonjiwe.

Lezi zimfanelo zenza i-granite ibe yinto ekahle yokwakha usayizi wangokwezifiso kanye nezisekelo zomshini owenziwe ngokwezifiso kanye nezingxenye ze-metrology ezifanaI-granite surface plate.

I-ZhongHui ikhiqiza imikhiqizo ye-granite ye-bespoke edalelwe ukusekela izidingo ezithile zokulinganisa.Lezi zinto ezihlosiwe ziyahlukahluka kuyeimiphetho eqondile toizikwele ezintathu.Ngenxa yemvelo eguquguqukayo ye-granite, iizingxenyeingakhiqizwa kunoma yimuphi usayizi odingekayo;zigqoke kanzima futhi zihlala isikhathi eside.

Izinzuzo ze-Granite Surface Plates
Ukubaluleka kokulinganisa endaweni elinganayo kwasungulwa umsunguli waseBrithani uHenry Maudsley ngeminyaka yawo-1800.Njengomsunguli wethuluzi lomshini, wanquma ukuthi ukukhiqizwa okungaguquki kwezingxenye kudinga indawo eqinile yokulinganisa okuthembekile.

Uguquko lwezimboni lwadala isidingo sendawo yokulinganisa, ngakho inkampani yobunjiniyela i-Crown Windley yakha amazinga okukhiqiza.Izindinganiso zamapuleti angaphezulu zaqala ukusethwa yiCrown ngo-1904 zisebenzisa insimbi.Njengoba isidingo nezindleko zensimbi zanda, ezinye izinto zokwakha indawo yokulinganisa zaphenywa.

EMelika, umdali wetshe lesikhumbuzo u-Wallace Herman wasungula ukuthi igwadule elimnyama laliyipuleti eliphezulu elingcono kakhulu elihlukile kunelensimbi.Njengoba i-granite ingeyona i-magnetic futhi ingagqwali, ngokushesha yaba indawo yokulinganisa ekhethwayo.

Ipuleti elingaphezulu kwegwadle liwutshalomali olubalulekile kumalabhorethri nezindawo zokuhlola.I-granite surface plate engu-600 x 600 mm ingafakwa endaweni yokusekela.Izitendi zinikeza ubude bokusebenza obungu-34” (0.86m) namaphoyinti amahlanu alungisekayo okulinganisa.

Ukuze uthole imiphumela yokulinganisa ethembekile nengaguquguquki, i-granite surface plate ibalulekile.Njengoba indawo engaphezulu iyindiza ebushelelezi futhi ezinzile, yenza amathuluzi akwazi ukusetshenziswa ngokucophelela.

Izinzuzo eziyinhloko ze-granite surface plate yilezi:

• Akubonakali
• Ingazweli kumakhemikhali nokugqwala
• I-coefficient ephansi yokunwetshwa uma iqhathaniswa nensimbi yenqola kangangokuthi ithintwa kancane ukushintsha kwezinga lokushisa
• Iqinile ngokwemvelo futhi igqoke kanzima
• Indiza yendawo engaphezulu ayithinteki uma iklwejwa
• Ngeke ukugqwala
• Okungewona uzibuthe
• Kulula ukuhlanza nokunakekela
• Ukulinganisa nokufaka kabusha ingaphezulu kungenziwa endaweni
• Ifanele ukubhoboza okokufaka kokusekela okunentambo
• Ukunciphisa ukudlidliza okuphezulu

Ezitolo eziningi, amagumbi okuhlola namalabhorethri, amapuleti angaphezulu egwadle athembeke kuwo njengesisekelo sokulinganisa okunembile.Ngenxa yokuthi zonke izilinganiso zomugqa zincike endaweni eyinkomba enembile lapho kuthathwa khona ubukhulu bokugcina, amapuleti angaphezulu ahlinzeka ngendiza eyinkomba engcono kakhulu yokuhlolwa komsebenzi kanye nesakhiwo ngaphambi komshini.Futhi ayizisekelo ezikahle zokwenza izilinganiso zobude kanye nezindawo zokugawula.Ngaphezu kwalokho, izinga eliphezulu lokusicaba, ukuzinza, ikhwalithi iyonke kanye nokusebenza kahle kubenza babe yisinqumo esihle sokukhweza amasistimu egeji emishini eyinkimbinkimbi, e-electronic kanye ne-optical.Kunoma iyiphi yalezi zinqubo zokulinganisa, kubalulekile ukugcina amapuleti angaphezulu elinganiselwe.

Phinda Izilinganiso kanye Flatness
Kokubili ukucaba nokuphindaphinda izilinganiso kubalulekile ukuze kuqinisekiswe indawo enembayo.I-flatness ingabhekwa njengawo wonke amaphuzu angaphezulu aqukethwe ngaphakathi kwezindiza ezimbili ezifanayo, indiza eyisisekelo kanye nendiza yophahla.Isilinganiso sebanga phakathi kwezindiza wukucaba kwendawo yonke.Lesi silinganiso sokucaba sivame ukubekezelela futhi singabandakanya ukuqokwa kwebanga.

Ukubekezelela ukucabana kwamabanga amathathu ajwayelekile kuchazwa ekucacisweni kombuso njengoba kunqunywa ifomula elandelayo:
Ibanga Laselabhorethri AA = (40 + diagonal² / 25) x 0.000001 iyintshi (ihlangothi elilodwa)
IBanga Lokuhlola A = IBanga Laselabhorethri AA x 2
Igumbi Lethuluzi IBanga B = IBanga Laselabhorethri AA x 4

Ngaphezu kokuqina, ukuphindaphinda kufanele kuqinisekiswe.Ukulinganisa okuphindayo ukukalwa kwezindawo eziphansi zendawo.Kuyisilinganiso esithathwa noma yikuphi phezu kwepuleti elizophinda ngaphakathi kokubekezelelana okushiwo.Ukulawula ukucaba kwendawo ukuze kube nokubekezelelana okuqinile kunokucaba sekukonke kuqinisekisa ushintsho kancane kancane kuphrofayela yokucaba kwendawo, ngaleyo ndlela kuncishiswe amaphutha endawo.

Ukuqinisekisa ukuthi ipuleti elingaphezulu lihlangabezana nakho kokubili ukucaba nokucaciswa kokulinganisa okuphindayo, abakhiqizi bamapuleti angaphezulu kwegwadle kufanele basebenzise i-Federal Specification GGG-P-463c njengesisekelo sokucaciswa kwabo.Leli zinga likhuluma ngokunemba kokulinganisa okuphindaphindwayo, izakhiwo zezinto ezibonakalayo zamapuleti angaphezulu, ukuphela kwendawo, indawo yephoyinti lokusekela, ukuqina, izindlela ezamukelekayo zokuhlola kanye nokufakwa kwezinto ezifakiwe ezinentambo.

Ngaphambi kokuthi ipuleti elingaphezulu ligqokwe ngaphezu kokucaciswa kokucaba okuphelele, lizobonisa izigxobo ezigugile noma ezinamagagasi.Ukuhlolwa kwanyanga zonke kwamaphutha okulinganisa okuphinda kusetshenziswa igeji yokufunda ephindayo kuzokhomba izindawo ezigugile.Igaji yokufunda ephindayo iyithuluzi elinemba okuphezulu elithola iphutha lasendaweni futhi lingaboniswa kusikhulisi se-electronic magnification high.

Ihlola Ukunemba Kwepuleti
Ngokulandela iziqondiso ezimbalwa ezilula, ukutshalwa kwezimali ku-granite surface plate kufanele kuhlale iminyaka eminingi.Ngokuya ngokusetshenziswa kwepuleti, indawo yesitolo nokunemba okudingekayo, imvamisa yokuhlola ukunemba kwepuleti elingaphezulu liyahlukahluka.Umthetho ojwayelekile owokuthi ipuleti elisha lithole ukulinganiswa kabusha okugcwele phakathi nonyaka owodwa wokuthenga.Uma ipuleti lisetshenziswa njalo, kuyatuseka ukuthi lesi sikhawu sifinyezwe sibe yizinyanga eziyisithupha.

Ngaphambi kokuthi ipuleti elingaphezulu ligqokwe ngaphezu kokucaciswa kokucaba okuphelele, lizobonisa izigxobo ezigugile noma ezinamagagasi.Ukuhlolwa kwanyanga zonke kwamaphutha okulinganisa okuphinda kusetshenziswa igeji yokufunda ephindayo kuzokhomba izindawo ezigugile.Igaji yokufunda ephindayo iyithuluzi elinemba okuphezulu elithola iphutha lasendaweni futhi lingaboniswa kusikhulisi se-electronic magnification high.

Uhlelo lokuhlola olusebenzayo kufanele lubandakanye ukuhlola okuvamile nge-autocollimator, okuhlinzeka ngokulinganiswa kwangempela kokucaba okuphelele okulandelekayo ku-National Institute of Standards and Technology (NIST).Ukulinganisa okuphelele komkhiqizi noma inkampani ezimele kuyadingeka ngezikhathi ezithile.

Izinguquko Phakathi Kwezilinganiso
Kwezinye izimo, kukhona ukuhluka phakathi kokulinganisa kwamapuleti angaphezulu.Kwesinye isikhathi izinto ezinjengokushintsha kwendawo okubangelwa ukuguga, ukusetshenziswa okungalungile kwempahla yokuhlola noma ukusetshenziswa kwezinto ezingalinganiselwe zingabalela lokhu kuhlukahluka.Nokho, izici ezimbili ezivame kakhulu izinga lokushisa nokusekela.

Enye yezinto eziguquguqukayo ezibaluleke kakhulu izinga lokushisa.Isibonelo, indawo engaphezulu kungenzeka ukuthi igezwe ngesisombululo esishisayo noma esibandayo ngaphambi kokulinganisa futhi akuvunyelwe isikhathi esanele sokujwayela.Ezinye izimbangela zokushintsha kwezinga lokushisa zihlanganisa okusalungiswa komoya obandayo noma oshisayo, ukukhanya kwelanga, ukukhanya okungaphezulu noma eminye imithombo yokushisa okukhazimulayo ebusweni bepuleti.

Kungase futhi kube nokuhluka kwezinga lokushisa eliqondile phakathi kobusika nehlobo.Kwezinye izimo, ipuleti alivunyelwe isikhathi esanele sokujwayela ngemva kokuthunyelwa.Kungumqondo omuhle ukurekhoda izinga lokushisa elime mpo ngesikhathi ukulinganisa kwenziwa.

Esinye isizathu esivamile sokuhlukahluka kokulinganisa ipuleti elingasekelwa ngokungafanele.Ipuleti elingaphezulu kufanele lisekelwe emaphuzwini amathathu, abekwe ngokufanelekile angama-20% ubude ukusuka ekugcineni kwepuleti.Izisekelo ezimbili kufanele zibekwe ku-20% wobubanzi phakathi ukusuka ezinhlangothini ezinde, futhi ukusekelwa okusele kufanele kugxile.

Amaphuzu amathathu kuphela angahlala aqinile kunoma yini ngaphandle kwendawo enembayo.Ukuzama ukusekela ipuleti ngamaphuzu angaphezu kwamathathu kuzokwenza ukuthi ipuleti lithole ukwesekwa kwalo ezinhlanganisela ezihlukahlukene zamaphuzu amathathu, okungeke kube amaphuzu amathathu afanayo lapho lisekelwa khona ngesikhathi sokukhiqiza.Lokhu kuzokwethula amaphutha njengoba ipuleti lichezuka ukuze lihambisane nokuhlelwa okusha kosekelo.Cabangela ukusebenzisa izitendi zensimbi ezinemishayo yokusekela eklanyelwe ukuhambisana namaphoyinti afanele okusekela.Izitendi zale njongo zivame ukutholakala kumkhiqizi wamapuleti angaphezulu.

Uma ipuleti lisekelwa kahle, ukulinganisa okunembile kuyadingeka kuphela uma isicelo sikucacisa.Ukulinganisa akudingekile ukuze kugcinwe ukunemba kwepuleti elisekelwe kahle.

Kubalulekile ukugcina ipuleti lihlanzekile.Uthuli oluqhunyiswa emoyeni ngokuvamile luwumthombo omkhulu kakhulu wokuguga nokudabuka epuletini, njengoba luvamise ukushumeka ezintweni zokusebenza nasezindaweni zokuthintana zamageji.Vala amapuleti ukuze uwavikele othulini nasekulimaleni.Impilo yokugqoka inganwetshwa ngokumboza ipuleti uma lingasetshenziswa.

Nweba Impilo YePlate
Ukulandela imihlahlandlela embalwa kuzonciphisa ukuguga kwepuleti le-granite elingaphezulu futhi ekugcineni, kunwebe impilo yalo.

Okokuqala, kubalulekile ukugcina ipuleti lihlanzekile.Uthuli oluqhunyiswa emoyeni ngokuvamile luwumthombo omkhulu kakhulu wokuguga nokudabuka epuletini, njengoba luvamise ukushumeka ezintweni zokusebenza nasezindaweni zokuthintana zamageji.

Kubalulekile futhi ukumboza amapuleti ukuze uvikeleke othulini nasekulimaleni.Impilo yokugqoka inganwetshwa ngokumboza ipuleti uma lingasetshenziswa.

Zungezisa ipuleti ngezikhathi ezithile ukuze indawo eyodwa ingatholi ukusetshenziswa ngokweqile.Futhi, kunconywa ukuthi kuthathelwe indawo amaphedi okuxhumana ensimbi ku-gaging ngamaphedi e-carbide.

Gwema ukubeka ukudla noma iziphuzo ezibandayo epuletini.Iziphuzo ezibandayo eziningi zine-carbonic noma i-phosphoric acid, engancibilikisa amaminerali athambile futhi ishiye imigodi emincane phezulu.

Lapho Ozobuyela Khona
Uma ipuleti elingaphezulu kwegwadle lidinga ukuphinde libekwe phezulu, cabanga ukuthi le sevisi yenziwe endaweni noma endaweni yokulinganisa.Kuhlale kuncono ukuthi ipuleti liphinde libuyele embonini noma endaweni ezinikele.Kodwa-ke, uma ipuleti lingagqokile kabi kakhulu, ngokuvamile phakathi kweyintshi engu-0.001 yokubekezelelana okudingekayo, lingaphinde livulwe esizeni.Uma ipuleti ligqokwe lifike endaweni lapho lingaphezu kuka-0.001 intshi ngenxa yokubekezelelana, noma uma libhodlozwe kabi noma lifakwe i-nicked, kufanele lithunyelwe efekthri ukuze ligaywe ngaphambi kokuphinda liphindwe.

Indawo yokulinganisa inemishini kanye nesethingi yefekthri ehlinzeka ngezimo ezikahle zokulinganiswa kwepuleti okufanele nokusebenza kabusha uma kunesidingo.

Kufanele kuqashelwe kakhulu ekukhetheni uchwepheshe osebenza endaweni yokulinganisa nokufaka kabusha izulu.Cela ukugunyazwa futhi uqinisekise okokusebenza okuzosetshenziswa uchwepheshe kunokulinganiswa okulandelekayo kwe-NIST.Okuhlangenwe nakho nakho kuyisici esibalulekile, njengoba kuthatha iminyaka eminingi ukufunda indlela yokuhlanganisa ngokunembile igwadle.

Izilinganiso ezibucayi ziqala ngepuleti eliphezulu legwadle elinembayo njengesisekelo.Ngokuqinisekisa ireferensi ethembekile ngokusebenzisa ipuleti langaphezulu elilinganiswe kahle, abakhiqizi banethuluzi elilodwa elibalulekile lokulinganisa okuthembekile nezingxenye zekhwalithi engcono.
