Umlando Wakuqala Wezicwecwe Ezingaphezulu ZeGranite

Ngaphambi kweMpi Yezwe II, Abakhiqizi basebenzisa ama-Steel Surface Plates ukuze bahlole izingxenye.Phakathi neMpi Yezwe II isidingo sensimbi sanda kakhulu, futhi inqwaba ye-Steel Surface Plates yancibilika.Kwakudingeka ukushintshwa, futhi iGranite yaba into ekhethwayo ngenxa yezakhiwo zayo eziphakeme ze-metrological.

Izinzuzo eziningana zegwadle ngaphezu kwensimbi zaba sobala.I-Granite iqinile, nakuba i-brittle futhi ingaphansi kokuqhekeka.Ungakwazi ukugoqa iGranite ibe isicaba esikhulu futhi ngokushesha kunensimbi.I-Granite nayo inendawo efiselekayo yokunwetshwa okushisayo okuphansi uma kuqhathaniswa nensimbi.Ngaphezu kwalokho, uma ipuleti lensimbi lidinga ukulungiswa, kwakudingeka likulwe ngesandla izingcweti ezazisebenzisa amakhono azo ekwakheni kabusha amathuluzi omshini.

Njengenothi eseceleni, amanye ama-Steel Surface Plates asasetshenziswa nanamuhla.

Izakhiwo ze-Metrological zama-Granite Plates

I-Granite idwala elivuthayo elakhiwe ukuqhuma kwentaba-mlilo.Uma kuqhathaniswa, imabula i-limestone ye-metamorphosed.Ngokusetshenziswa kwe-metrology, i-granite ekhethiwe kufanele ihlangabezane nezimfuneko ezithile ezishiwo ku-Federal Specification GGG-P-463c, kusukela manje kuqhubeke ebizwa ngokuthi i-Fed Specs, futhi ngokukhethekile, Ingxenye 3.1 3.1 Phakathi Kwezicaciso Ze-Fed, igwadle kufanele libe inhlawulo ukuya kokuthungwa okumaphakathi.

I-Granite iyimpahla eqinile, kodwa ubulukhuni bayo buyahlukahluka ngenxa yezizathu eziningana.Uchwepheshe wepuleti legwadle onolwazi angalinganisa ubulukhuni ngombala wayo oyinkomba yokuqukethwe kwayo kwequartz.Ukuqina kwe-Granite kuyisici esichazwe ngokwengxenye ngenani lokuqukethwe kwe-quartz kanye nokuntuleka kwe-mica.Ama-granite abomvu ne-pink avame ukuba nzima kakhulu, ama-gray anobunzima obuphakathi, kanti amnyama athambile kakhulu.

I-Young's Modulus of Elasticity isetshenziselwa ukuveza ukuguquguquka noma inkomba yokuqina kwetshe.I-pink granite ilinganisa amaphuzu angu-3-5 esikalini, ama-gray amaphuzu angu-5-7 kanti abamnyama amaphuzu angu-7-10.Uma inombolo encane, i-granite ivame ukuba nzima.Inkulu inombolo, igwadle ethambile futhi nezimo more.Kubalulekile ukwazi ubulukhuni beGranite lapho ukhetha ubukhulu obudingekayo kumamaki okubekezelela kanye nesisindo sezingxenye namageji abekwe phezu kwawo.

Ezinsukwini zakudala lapho kwakukhona ochwepheshe bemishini bangempela, abaziwa ngezincwajana zabo zetafula lama-trig emaphaketheni amahembe, igwagwa elimnyama lalibhekwa “njengelingcono kakhulu.”Okungcono kakhulu kuchazwa njengohlobo olunikeze ukumelana kakhulu ukugqoka noma okunzima kakhulu.Enye i-drawback ukuthi ama-granite aqinile ajwayele ukucwilisa noma ukucula kalula.Ama-machinists ayeqiniseka kakhulu ukuthi i-granite emnyama yayingcono kakhulu kangangokuthi abanye abakhiqizi be-granite ebomvana babadaya abamnyama.

Ngizibonele mathupha ipuleti elehliswa ku-forklift lapho lisuswa endaweni yokugcina.Ipuleti lashaya phansi lahlukana kabili liveza umbala ophinki wangempela.Qaphela uma uhlela ukuthenga igwadle elimnyama e-China.Sincoma ukuthi uchithe imali yakho ngenye indlela.Ipuleti legwadle lingahluka ngobulukhuni ngaphakathi kwalo.I-streak ye-quartz ingaba nzima kakhulu kune-surface plate.Ungqimba lwe-gabbro emnyama lungenza indawo ithambe kakhulu.Ochwepheshe abaqeqeshwe kahle, abanolwazi lokulungisa amapuleti angaphezulu bayakwazi ukuphatha lezi zindawo ezithambile.

I-Surface Plate Amabanga

Kunamabanga amane amapuleti angaphezulu.IBanga leLabhorethri AA no-A, Ukuhlolwa Kwegumbi IBanga B, kanti elesine yiBanga Lokusebenzela.I-AA yeBanga kanye no-A yizona ezihamba phambili ezinokubekezelela ukucaba okungcono kuno-0.00001 kupuleti leBanga le-AA.AmaBanga e-Workshop okuyiwona angamafulethi amancane futhi njengoba igama lisho, enzelwe ukusetshenziswa emagumbini amathuluzi.Lapho iBanga AA, iBanga A kanye neBanga B kuhloswe ngalo ukusetshenziswa endaweni yokuhlola noma yokulawula ikhwalithi.

PUkuhlolwa kwe-roper For Surface Plate Calibration

Bengilokhu ngitshela amakhasimende ami ukuthi ngingakhipha noma yimuphi umntwana oneminyaka engu-10 ebandleni lami futhi ngibafundise ezinsukwini ezimbalwa nje ukuhlola ipuleti.Akunzima.Idinga indlela ethile yokwenza umsebenzi ngokushesha, amasu umuntu awafunda ngokuhamba kwesikhathi nokuphindaphinda okuningi.Kufanele ngikwazise, ​​futhi angikwazi ukugcizelela ngokwanele, I-Fed Spec GGG-P-463c AKUYONA inqubo yokulinganisa!Okuningi ngalokho kamuva.

Ukulinganiswa kokuhlolwa kwe-flatness sekukonke (Ifasitelana elisho ukuthini) kanye Nokuphindwaphindwa (ukugqokwa kwasendaweni) kuyadingeka Ngokuvumelana Nemibandela Ye-Fed.Okuwukuphela kokuhlukile kulokhu ngamapuleti amancane lapho ukuphindaphinda kuyadingeka kuphela.

Futhi, futhi okubaluleke kakhulu njengezinye izivivinyo, ukuhlolwa kwama-gradients ashisayo.(Bheka i-Delta T ngezansi)

Umfanekiso 1

Ukuhlolwa kwe-Flatness kunezindlela ezi-4 ezigunyaziwe.Amaleveli e-elekthronikhi, i-autocollimation, i-laser kanye nedivayisi eyaziwa ngokuthi isitholi sendiza.Sisebenzisa kuphela amaleveli e-elekthronikhi ngoba ayindlela enembe kakhulu futhi eshesha kakhulu ngezizathu ezimbalwa.

Ama-Lasers nama-autocollimators asebenzisa i-beam yokukhanya eqonde kakhulu njengereferensi.Umuntu wenza isilinganiso sobuqotho sepuleti lengaphezulu legwadle ngokuqhathanisa ukuhluka kwebanga phakathi kwe-surface plate kanye ne-light beam.Ngokuthatha i-beam yokukhanya eqondile, uyishaye kuthagethi yesibonisi kuyilapho uhambisa okuqondiwe kwesibonisi phansi kwepuleti elingaphezulu, ibanga eliphakathi kwe-beam ekhishiwe kanye ne-return beam isilinganiso sokuqondisa.

Nansi inkinga ngale ndlela.Okuqondiwe kanye nomthombo kuthintwa ukudlidliza, izinga lokushisa le-ambient, okuqondiwe okungaphansi kwesicaba noma okuklwetshiwe, ukungcoliswa emoyeni, nokunyakaza komoya (ama-currents).Konke lokhu kunikela ngezingxenye ezengeziwe zephutha.Ngaphezu kwalokho, umnikelo wephutha lomsebenzisi ovela ekuhlolweni nge-autocollimator mkhulu.

Umsebenzisi we-autocollimator onesipiliyoni angenza izilinganiso ezinembe kakhulu kodwa usabhekene nezinkinga zokungaguquguquki kokufundwa ikakhulukazi emabangeni amade njengoba ukuboniswa kuvame ukunwebeka noma ukufiphala kancane.Futhi, ithagethi engaphansi kunesicaba kanye nosuku olude lokulunguza ilensi kukhiqiza amaphutha engeziwe.

Idivayisi yokukhomba indiza iwubulima nje.Le divayisi isebenzisa okuthi kuqonde ngqo (uma kuqhathaniswa ne-collimated ngokwedlulele noma i-laser beam yokukhanya) njengereferensi yayo.Umshini womshini awusebenzisi nje inkomba evamise ukuba nokulungiswa okungu-20 u Intshi kuphela kodwa ukungaqondi kahle kwebha nezinto ezihlukile zengeza ngokuphawulekayo amaphutha esilinganisweni.Ngokombono wethu, nakuba indlela yamukelekile, ayikho ilebhu enekhono engasebenzisa idivayisi yokuthola indawo yendiza njengethuluzi lokugcina lokuhlola.

Amaleveli e-elekthronikhi asebenzisa amandla adonsela phansi njengereferensi yawo.Amaleveli e-elekthronikhi ahlukile awathintwa ukudlidliza.Zinokulungiswa okuphansi njengesekhondi elingu-.1 arc futhi izilinganiso ziyashesha, zinembile futhi kunomnikelo omncane kakhulu wephutha ovela ku-opharetha onolwazi.I-Plane Locators noma ama-autocollimator awanikezeli nge-topographical ekhiqizwe ngekhompuyutha (Umfanekiso 1) noma iziqephu ze-isometric (Umfanekiso 2) wendawo.
