Cov khoom siv granite precision feem ntau siv rau hauv ntau yam kev siv hauv kev lag luam, qhov twg qhov tseeb thiab kev ruaj khov siab yog qhov tseem ceeb. Cov khoom no yog ua los ntawm cov granite zoo uas tau raug xaiv thiab ua tiav kom ntseeg tau tias muaj cov yam ntxwv sib xws thiab kev ruaj khov zoo heev.
Kev siv granite ua cov khoom siv rau cov khoom siv precision muaj keeb kwm ntev, txij li thaum cov neeg Iyiv thaum ub uas siv granite hauv kev tsim lawv cov pyramids. Niaj hnub no, cov khoom siv granite precision raug siv hauv kev lag luam xws li kev tsim kho precision thiab metrology mus rau optics thiab semiconductor manufacturing.
Cov yam ntxwv tseem ceeb ntawm granite uas ua rau nws yog cov khoom siv zoo tshaj plaws rau cov khoom siv precision yog nws qhov ceev ceev, porosity tsawg, siab stiffness, thiab zoo heev thermal stability. Cov yam ntxwv no yog qhov tseem ceeb rau kev ua tiav cov theem siab ntawm kev raug thiab kev ruaj khov uas xav tau hauv ntau daim ntawv thov kev lag luam.
Ib qho ntawm kev siv ntau tshaj plaws ntawm cov khoom siv granite precision yog nyob rau hauv kev tsim cov khoom siv ntsuas precision xws li cov tshuab ntsuas sib koom ua ke (CMMs). Lub hauv paus granite ntawm CMM muab qhov chaw zoo heev rau kev ntsuas qhov tseeb, nrog rau lub platform ruaj khov rau cov khoom txav mus los ntawm lub tshuab.
Lwm daim ntawv thov rau cov khoom siv granite precision yog nyob rau hauv thaj chaw ntawm optics. Granite muaj qhov thermal expansion qis heev, ua rau nws yog cov khoom siv zoo heev rau cov iav precision thiab lwm yam khoom siv optical uas xav tau tswj lawv cov duab thiab qhov tseeb nyob rau hauv kev hloov pauv kub. Granite kuj muaj modulus siab heev ntawm elasticity, uas pab txo qhov kev cuam tshuam lossis khoov ntawm cov khoom siv optical.
Hauv kev lag luam semiconductor, cov khoom siv granite precision yog siv rau hauv kev tsim cov khoom siv tshuaj xyuas wafer thiab lwm yam cuab yeej tsim khoom precision. Qhov xwm txheej ruaj khov thiab ruaj khov ntawm granite muab cov khoom siv zoo tagnrho rau cov cuab yeej no, ua kom ntseeg tau tias muaj kev ntsuas raug thiab kev ua haujlwm zoo sib xws dhau sijhawm.
Cov khoom siv granite precision tuaj yeem tsim tau ntau qhov ntau thiab tsawg thiab cov duab kom haum rau ntau yam kev siv. Cov khoom no yog ua los ntawm kev siv cov txheej txheem machining tshwj xeeb uas tuaj yeem ua tiav qhov kev kam rau siab heev thiab qib siab ntawm qhov tseeb. Tsis tas li ntawd, qhov tiav ntawm qhov chaw ntawm cov khoom raug tswj hwm kom zoo kom ntseeg tau tias cov chaw du thiab tiaj tus uas tsis muaj qhov tsis zoo.
Xaus lus, cov khoom siv granite precision yog ib feem tseem ceeb ntawm ntau daim ntawv thov kev lag luam uas xav tau qhov tseeb thiab ruaj khov siab. Cov yam ntxwv tshwj xeeb ntawm granite ua rau nws yog cov khoom siv zoo tshaj plaws rau cov khoom no, muab kev ruaj khov, kev ruaj khov, thiab kev ua kom raug rau ntau yam cuab yeej thiab khoom siv. Raws li thev naus laus zis txuas ntxiv mus, qhov kev thov rau cov khoom siv granite precision yuav txuas ntxiv mus loj hlob, tsav tsheb kev tsim kho tshiab thiab kev nce qib hauv ntau yam lag luam.
