Lub hauv paus granite yog ib qho tseem ceeb hauv kev tsim cov khoom siv ua haujlwm precision. Nws ua haujlwm ua lub hauv paus rau cov khoom rhiab heev uas ua rau lub cuab yeej, muab kev ruaj khov thiab kev sib zog. Kev siv granite ua cov khoom siv hauv paus muaj ntau yam zoo, suav nrog kev ruaj khov siab, tiv taus kev nthuav dav thermal, thiab cov khoom zoo heev rau kev co.
Ib qho ntawm cov kev cai tseem ceeb tshaj plaws rau cov khoom siv ua haujlwm raug yog kev tswj hwm qhov tseeb. Txhua qhov kev hloov pauv me me hauv cov khoom siv lossis kev ruaj khov tuaj yeem ua rau muaj kev hloov pauv tsis zoo hauv cov khoom siv ua tiav, ua rau muaj qhov tshwm sim tsis raug. Kev siv granite ua cov khoom siv hauv paus rau cov khoom siv ua haujlwm raug txo qhov kev pheej hmoo ntawm kev hloov pauv los ntawm kev hloov pauv kub, av noo, thiab kev co, ua kom muaj kev raug zoo tas li dhau sijhawm.
Granite muaj qhov nthuav dav thermal tsawg, ua rau nws zoo tagnrho rau kev ua haujlwm precision. Cov khoom siv thermal expansion coefficient yog qhov tsis tseem ceeb, tsis zoo li lwm cov hlau thiab cov khoom sib xyaw, uas muaj cov coefficients siab dua. Cov coefficient ntawm thermal expansion txiav txim siab tias cov khoom siv hloov pauv ntau npaum li cas thaum nws qhov kub hloov pauv. Cov coefficient qis ntawm granite txhais tau tias nws muaj kev hloov pauv me me hauv qhov loj me thiab cov duab nyob rau hauv cov xwm txheej kub sib txawv, ua rau nws yog cov khoom siv zoo tagnrho rau cov khoom siv ua haujlwm precision.
Tsis tas li ntawd xwb, granite muaj zog ruaj khov thiab tiv taus xeb, yaig, thiab lwm yam kev hnav thiab tsim kua muag, ua rau nws zoo tagnrho rau kev siv rau hauv cov khoom siv ua haujlwm raug. Qhov ruaj khov ntawm cov khoom siv ua kom ntseeg tau tias cov khoom siv tsim los ntawm nws tsis khoov lossis deform dhau sijhawm, ua kom ntseeg tau tias muaj kev sib xws thoob plaws lub neej ntawm lub cuab yeej.
Xaus lus, kev siv granite ua cov khoom siv rau cov khoom siv ua haujlwm precision muab ntau yam txiaj ntsig, suav nrog kev ruaj khov ntawm qhov ntev, kev co, thiab kev tiv taus kev hloov pauv kub. Cov khoom siv no muab lub hauv paus ruaj khov rau cov khoom rhiab heev uas ua rau lub cuab yeej, ua kom muaj kev raug thiab lub neej ntev. Hauv lub ntiaj teb niaj hnub no ntawm kev tsim kho siab, kev siv cov khoom siv granite rau cov khoom siv ua haujlwm precision ua pov thawj tias yog kev xaiv txhim khu kev qha thiab muaj txiaj ntsig.
