Granite bases ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov ntsuas rov ua haujlwm ntawm kev sib koom tes ntsuas tshuab (CMMs). Qhov tseeb thiab qhov tseeb ntawm CMMs yog qhov tseem ceeb thoob plaws ntau qhov kev lag luam, suav nrog kev tsim khoom thiab kev tswj xyuas zoo, qhov twg txawm tias qhov sib txawv me ntsis tuaj yeem ua rau muaj qhov yuam kev loj. Yog li ntawd, kev xaiv ntawm cov khoom siv hauv paus yog qhov tseem ceeb, thiab granite yog qhov kev xaiv zoo rau ntau qhov laj thawj.
Ua ntej, granite paub txog nws qhov tshwj xeeb ruaj khov. Nws muaj qhov qis coefficient ntawm thermal expansion, uas txhais tau hais tias nws tsis nthuav lossis cog lus nrog qhov kub thiab txias. Qhov kev ruaj ntseg no yog qhov tseem ceeb rau kev tswj xyuas cov kev ntsuas zoo ib yam, vim tias qhov kub thiab txias tuaj yeem ua rau kev ntsuas sib txawv. Los ntawm kev muab lub platform ruaj khov, lub hauv paus granite ua kom ntseeg tau tias CMM tuaj yeem xa cov txiaj ntsig rov qab, tsis hais txog kev hloov pauv hauv ib puag ncig.
Thib ob, granite yog ib qho nyuaj thiab ntom, uas txo qis kev vibrations thiab kev cuam tshuam sab nraud. Hauv ib puag ncig kev tsim khoom, kev vibrations tsim los ntawm cov tshuab lossis tib neeg kev khiav tsheb tuaj yeem cuam tshuam qhov ntsuas qhov tseeb. Qhov ntom ntom ntawm granite absorbs cov kev vibrations, tso cai rau lub tshuab ntsuas kev sib koom tes ua haujlwm nyob rau hauv ib puag ncig tswj ntau dua. Qhov kev vibration absorption no pab txhim kho kev ntsuas rov ua dua vim tias lub tshuab tuaj yeem tsom mus rau kev ntes cov ntaub ntawv meej yam tsis muaj kev cuam tshuam.
Tsis tas li ntawd, granite nto feem ntau polished mus rau qib siab ntawm flatness, uas yog qhov tseem ceeb rau kev ntsuas kom raug. Lub tiaj tiaj ua kom ntseeg tau tias CMM sojntsuam tswj kev sib raug zoo nrog cov khoom ua haujlwm, ua kom cov ntaub ntawv khaws cia ruaj khov. Txhua qhov tsis sib xws ntawm lub hauv paus tuaj yeem ua rau qhov tsis raug, tab sis qhov sib xws ntawm granite nto txo qhov kev pheej hmoo no.
Hauv cov ntsiab lus, granite hauv paus tau txhim kho qhov ntsuas rov ua tau zoo ntawm CMMs los ntawm lawv cov kev ruaj ntseg, rigidity thiab flatness. Los ntawm kev muab lub hauv paus txhim khu kev qha, granite ua kom ntseeg tau tias CMMs tuaj yeem muab cov kev ntsuas raug thiab zoo ib yam, uas yog qhov tseem ceeb rau kev tswj cov qauv zoo thoob plaws kev lag luam.
