Lub tshuab ua kom sib haum nrog lub tshuab ntsuas (CMM) yog cov khoom siv ua kom haum siv rau ntsuas thiab kuaj xyuas cov khoom nrog qib siab ntawm qhov raug. Qhov tseeb ntawm CMM yog tus nqi them ncaj qha rau qhov zoo thiab hardness ntawm granite puag siv hauv nws txoj kev tsim kho.
Granite yog ib txwm tshwm sim pob zeb uas muaj cov khoom tshwj xeeb uas ua rau nws zoo rau kev siv ua lub hauv paus rau CMM. Firstly, nws muaj qhov tsawg heev coefficient ntawm thermal expansion, uas txhais tau tias nws tsis nthuav dav lossis cog lus nrog qhov ntsuas kub. Cov cuab yeej no kom ntseeg tau tias lub tshuab thiab nws cov khoom siv tswj tau lawv txoj kev ua kom nruj thiab tsis muaj kev cuam tshuam los ntawm kev hloov kub ib puag ncig uas tuaj yeem cuam tshuam nws qhov kev ntsuas ntsuas qhov tseeb.
Thib ob, Granite muaj qib siab ntawm kev tawv thiab nruj. Qhov no ua rau nws nyuaj rau khawb lossis deform, uas yog qhov tseem ceeb rau kev tswj cov kev ntsuas raug raws sijhawm. Txawm tias cov khawb av me me lossis deformations ntawm granite bound tuaj yeem cuam tshuam qhov tseeb ntawm lub tshuab.
Lub Hardness ntawm Granite Bound kuj cuam tshuam rau qhov ruaj khov thiab rov ua dua ntawm cov ntsuas tau coj los ntawm CMM. Ib qho kev txav me me lossis kev co hauv lub hauv paus tuaj yeem ua rau qhov tsis raug nyob hauv cov ntsuas ntsuas uas tuaj yeem ua rau muaj qhov tsis muaj tseeb. Lub zog nyuaj ntawm granite lub hauv paus ntseeg tau tias lub tshuab nyob ruaj khov thiab tuaj yeem tswj hwm nws txoj haujlwm ncaj txawm tias thaum ntsuas.
Ntxiv rau nws lub luag haujlwm hauv kev ntsuas kev ntsuas qhov tseeb, cov granite puag ntawm cov CMM kuj tseem yog lub luag haujlwm tseem ceeb hauv lub tshuab uas tseem ceeb tshaj plaws thiab ntev. Qib siab ntawm hardness thiab rigidity ntawm granite kom lub tshuab muaj peev xwm tiv taus cov hnav thiab tig nws lub sijhawm ntev.
Hauv kev xaus, lub hardness ntawm granite puag yog ib qho tseem ceeb ntawm qhov tseeb hauv qhov tseeb ntawm CMM. Nws ua kom pom tseeb tias lub tshuab tuaj yeem tsim kho ncaj ncees, kev ntsuas kev sim ntau dua li lub sijhawm ntev thiab tiv thaiv cov hnav thiab kua muag txhua hnub siv. Xws li, nws yog qhov tseem ceeb kom ntseeg tau tias cov granite luj siv nyob rau hauv kev tsim kho ntawm cmm yog qhov zoo thiab hardness kom ua tiav cov txiaj ntsig zoo tshaj plaws.
