Granite yog cov khoom siv dav hauv kev tsim cov tshuab ua kom sib haum (cmm) vim nws cov khoom siv lub cev tshwj xeeb. CMMS yog cov cuab yeej tseem ceeb siv nyob rau hauv ntau yam kev lag luam rau kev ntsuas geometry ntsuas yog cov duab sib xyaw thiab cov khoom. Cov cms tau siv nyob rau hauv kev tsim khoom lag luam thiab cov txheej txheem ntau lawm yuav tsum muaj qhov tseeb thiab ruaj khov los tswj qhov raug thiab kev ua haujlwm ntawm kev ntsuas. Granite, ib hom ntawm cov khoom siv tsis zoo rau cov ntawv thov no raws li nws muaj txhav zoo, siab thermal kev nthuav dav coefficients.
Tiffness yog ib qho tseem ceeb ntawm cov khoom tseem ceeb uas xav tau rau kev ntsuas ntsuas ruaj khov, thiab cov pob zeb ruaj khov rau lwm cov ntaub ntawv, xws li hlau lossis hlau. Granite yog qhov tsis muaj tuab, tawv thiab tsis muaj cov khoom siv, uas tsis yog deform nyob rau hauv thauj, kom ntsuas tau lub pluaj CMM txawm khaws nws cov duab txawm nyob hauv kev thauj khoom sib txawv. Qhov no ua kom pom tseeb tias kev ntsuas ntsuas tau muaj tseeb, rov ua dua, thiab ua kom nruj.
Thermal ruaj khov yog lwm qhov tseem ceeb hauv kev tsim ntawm cms. Granite muaj tsawg thermal expansion coeffic tsis yog vim nws cov qauv molecular thiab ntom. Yog li ntawd, nws yog qhov ruaj khov nyob rau ntau qhov kub thiab txias thiab ua rau cov kev pauv hloov tsawg dua vim yog hloov pauv kub. Cov qauv granite muaj cov coefficient ntawm thermal expansion, uas ua rau nws tiv taus cov cua sov heev. Raws li kev lag luam cuam tshuam nrog ntau yam khoom lag luam thiab cov ntawv thov uas ua haujlwm ntawm cov khoom kub sib txawv, siv cov ntsuas ntsuas kom raug, tsis hais txog qhov ntsuas kub hloov.
Lub seem ruaj khov ntawm granite yog sib xws, txhais tau tias nws nyob hauv nws cov thawj duab thiab nws lub hardness tsis hloov lub sijhawm. Qhov no kom ntseeg tau tias cov cheeb tsam granite ntawm ib CMM muab ib qho ruaj khov thiab twv ua tau zoo rau kev ntsuas ntsuas qhov chaw txav chaw. Nws ua rau lub kaw lus los ua cov ntsuas yog qhov tseeb thiab ua kom muaj kev ntsuas lub sijhawm, tsis tas yuav rov ntsuas dua.
Tsis tas li ntawd, Granite kuj tseem ruaj khov, yog li nws tuaj yeem tiv thaiv kev siv hnyav ntawm ib cmm dhau sijhawm, pub nws muab cov kev ntsuas thiab txhim khu kev ntsuas kom haum. Granite kuj tseem tsis sib nqus, uas yog qhov tseem ceeb uas yog qhov tseem ceeb hauv kev lag luam cov ntawv thov uas muaj kev sib nqus tuaj yeem cuam tshuam nrog kev ntsuas qhov raug.
Hauv cov ntsiab lus, GRANITE yog dav siv nyob rau hauv kev tsim cov tshuab ua ntu zus vim tias nws qhov tshwj xeeb txhav, thiab lub sijhawm nyob ruaj khov, thiab qhov seem sib xws, thiab kev nyob ruaj khov, thiab ntxaij tsis sib thooj. Cov xwm txheej no pab tau CMM muab cov qauv raug, rov ua dua, thiab ntsuas cov duab ntawm cov qauv ntau hauv ntau yam khoom siv thiab cov txheej txheem ntau lawm. Kev siv cov granite hauv kev tsim ntawm CMMS ua kom muaj kev ntsuas zoo rau cov txheej txheem txhim khu kev qha ntau dua thiab cov txheej txheem muaj kev tsim txiaj.
