Hauv ntiaj teb ntawm kev tswj xyuas zoo thiab kev ntsuas qhov tseeb, Lub Tshuab Ntsuas Sib Koom Tes (CMM) yog ib qho ntawm cov cuab yeej tseem ceeb tshaj plaws. Cov cuab yeej ntsuas siab heev no siv rau hauv ntau yam lag luam, suav nrog aerospace, automotive, kev kho mob, thiab kev tsim khoom, kom ntseeg tau tias muaj qhov tseeb hauv kev ntsuas khoom, kev tswj xyuas zoo, thiab kev tshuaj xyuas. Qhov tseeb ntawm CMM tsis yog nyob ntawm lub tshuab tsim thiab thev naus laus zis xwb tab sis kuj nyob ntawm qhov zoo ntawm cov ntaub ntawv siv hauv nws txoj kev tsim kho. Ib qho khoom siv tseem ceeb uas siv hauv CMM yog granite.
Granite yog ib qho ntawm cov ntaub ntawv siv ntau tshaj plaws hauv kev tsim cov CMMs vim nws cov yam ntxwv tshwj xeeb uas ua rau nws yog cov khoom siv zoo tagnrho rau cov txaj tshuab, spindle, thiab cov khoom ua haujlwm. Granite yog pob zeb uas tshwm sim ntuj uas muaj qhov ntom ntom, tawv, thiab ruaj khov. Cov yam ntxwv no ua rau nws yog cov khoom siv zoo tagnrho rau kev muab kev ruaj khov thiab thermal stability zoo tshaj plaws hauv CMM.
Kev xaiv granite ua cov khoom siv tseem ceeb rau CMM tsis yog kev txiav txim siab random xwb. Cov khoom siv tau raug xaiv vim nws cov khoom siv zoo heev, suav nrog kev ruaj khov siab, modulus siab ntawm elasticity, thermal expansion qis, thiab qib siab ntawm kev nqus kev co, yog li ua kom ntseeg tau tias muaj qib siab ntawm qhov tseeb thiab rov ua dua hauv kev ntsuas.
Granite muaj cov coefficient qis ntawm thermal expansion, uas txhais tau tias nws tuaj yeem tiv taus qhov kub thiab txias hloov pauv thiab tswj nws qhov ruaj khov. Cov cuab yeej no yog qhov tseem ceeb hauv CMM vim tias lub tshuab yuav tsum tswj nws qhov tiaj tus thiab ruaj khov txawm tias thaum raug rau qhov kub hloov pauv. Qhov ruaj khov thermal ntawm granite, ua ke nrog nws lub peev xwm los nqus cov kev co thiab txo cov suab nrov, ua rau nws yog cov khoom siv zoo tagnrho rau lub rooj ua haujlwm, spindle, thiab lub hauv paus.
Tsis tas li ntawd xwb, granite kuj tsis yog hlau nplaum thiab muaj kev tiv thaiv corrosion zoo, ua rau nws yog qhov kev xaiv zoo heev, tshwj xeeb tshaj yog nyob rau hauv kev lag luam tsim khoom uas kev ntsuas ntawm cov khoom hlau yog ib txwm muaj. Lub zog tsis yog hlau nplaum ntawm granite ua kom ntseeg tau tias nws tsis cuam tshuam nrog kev ntsuas ua los ntawm kev siv cov khoom siv hluav taws xob, uas tuaj yeem ua rau muaj qhov yuam kev hauv kev nyeem ntawv.
Tsis tas li ntawd xwb, granite yooj yim ntxuav thiab tswj, ua rau nws yog ib qho khoom siv txhim khu kev qha. Nws kuj siv tau ntev thiab ruaj khov, uas txhais tau tias nws muab lub tshuab ua haujlwm ntev dua, txo tus nqi hloov thiab kho.
Hauv kev xaus, kev xaiv granite ua lub spindle thiab workbench khoom siv rau CMM yog raws li nws cov khoom siv kho tshuab thiab thermal zoo heev. Cov khoom no ua rau CMM muab kev ntsuas tseeb thiab raug, tswj kev ruaj khov, thiab nqus cov kev co thiab suab nrov, ntawm lwm yam zoo. Kev ua tau zoo tshaj plaws thiab lub neej ntev ntawm CMM tsim nrog cov khoom granite ua rau nws yog kev nqis peev zoo rau txhua yam kev lag luam lossis lub koom haum uas xav tau kev ntsuas zoo thiab kev tswj xyuas zoo.
