CMM (lub tshuab ntsuas kev sib koom tes) tau dhau los ua ib qho cuab yeej tseem ceeb rau kev ntsuas qhov tseeb hauv ntau yam lag luam. Nws qhov tseeb thiab kev ruaj khov yog qhov kev txhawj xeeb tseem ceeb ntawm cov neeg siv. Ib qho ntawm cov khoom tseem ceeb ntawm CMM yog nws lub hauv paus, uas ua haujlwm ua lub hauv paus los txhawb tag nrho cov qauv, suav nrog lub probe, lub caj npab ntsuas, thiab software. Cov khoom siv hauv paus cuam tshuam rau CMM qhov kev ruaj khov mus sij hawm ntev, thiab granite yog ib qho ntawm cov khoom siv feem ntau siv rau CMM hauv paus vim nws cov khoom siv kho tshuab zoo heev.
Granite yog ib lub pob zeb ntuj uas muaj qhov ceev, tawv, thiab ruaj khov, uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau CMM bases. Granite muaj cov coefficient qis ntawm thermal expansion, ua rau nws tiv taus kev hloov pauv kub. Cov cuab yeej no tso cai rau CMM kom tswj tau nws qhov tseeb thiab ruaj khov txawm tias nyob rau hauv ib puag ncig hnyav, xws li lub Hoobkas uas muaj ntau yam kev hloov pauv kub. Ntxiv mus, granite qhov siab tawv thiab qis damping ua rau txo qis kev co, txhim kho CMM qhov kev ntsuas qhov tseeb.
Qhov nyuaj ntawm granite, uas yog ntsuas ntawm 6 thiab 7 ntawm Mohs nplai, pab txhawb rau CMM qhov ruaj khov mus sij hawm ntev. Lub hauv paus granite qhov nyuaj tiv thaiv kev hloov pauv lossis kev sib txhuam, ua kom CMM qhov tseeb dhau lub sijhawm ntev. Tsis tas li ntawd, granite qhov chaw tsis muaj qhov ntxeem tau txo qhov yuav muaj xeb lossis xeb, uas tuaj yeem ua rau lub hauv paus puas tsuaj thiab ua rau CMM tsis ruaj khov. Tus cwj pwm no kuj ua rau granite yooj yim ntxuav, uas yog qhov tseem ceeb hauv kev tswj hwm CMM qhov tseeb thiab qhov tseeb.
Lwm qhov uas yuav tsum xav txog yog tias CMM txoj kev ruaj khov tsis yog tsuas yog cuam tshuam los ntawm cov khoom siv hauv paus xwb tab sis kuj los ntawm seb lub hauv paus tau teeb tsa thiab tswj hwm li cas. Kev teeb tsa kom zoo thiab kev saib xyuas tsis tu ncua yog qhov tseem ceeb hauv kev ua kom CMM ruaj khov mus sij hawm ntev. Lub hauv paus yuav tsum tiaj tus thiab ruaj khov rau ntawm lub hauv paus ruaj khov, thiab qhov chaw hauv paus yuav tsum huv si thiab tsis muaj cov khib nyiab lossis cov kuab paug.
Xaus lus, qhov tawv ntawm lub hauv paus granite cuam tshuam rau CMM txoj kev ruaj khov mus sij hawm ntev. Kev siv granite ua cov khoom siv hauv paus muab CMM nrog cov khoom siv kho tshuab zoo heev, suav nrog qhov ceev siab, kev tawv, thiab kev co qis, ua rau muaj kev co tsawg dua thiab kev ntsuas qhov tseeb zoo dua. Tsis tas li ntawd, granite qhov chaw tsis muaj qhov ntxeem tau txo qhov yuav muaj xeb lossis xeb thiab yooj yim rau kev saib xyuas. Kev teeb tsa kom zoo thiab kev saib xyuas tsis tu ncua kuj tseem ceeb heev rau kev ua kom CMM ruaj khov thiab raug. Yog li ntawd, kev xaiv lub hauv paus granite rau CMM yog qhov kev xaiv zoo vim nws cov khoom zoo thiab kev ruaj khov mus sij hawm ntev.
