Granite puag yog ib qho kev xaiv nrov rau kev tsim kho ntawm Coordinate Measuring Machines (CMMs) xws li lub tshuab ntsuas peb-coordinate. Qhov no yog vim granite paub txog nws zoo heev hnav tsis kam thiab stability. Granite bases yog qhov nyiam rau CMMs vim lawv qhov kev ua haujlwm siab hauv cov damping, siab rigidity, thiab tshuaj stability. Hauv tsab xov xwm no, peb yuav tham txog qhov hnav tsis kam thiab kev pabcuam lub neej ntawm granite puag thiab seb nws puas yuav tsum tau hloov tsis tu ncua.
Kev hnav tsis kam ntawm granite hauv paus yog qhov zoo heev. Granite yog cov ntxhia hauv ntuj thiab suav tias yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws rau txiv neej. Nws muaj qhov tshwj xeeb hardness ntawm 6-7 ntawm Mohs nplai. Qhov no txhais tau hais tias granite muaj zog heev rau kev puas tsuaj thiab tuaj yeem tiv taus ntau yam cuam tshuam yam tsis muaj kev puas tsuaj. Ntxiv mus, granite muaj kev tiv thaiv zoo rau cov tshuaj lom neeg uas tuaj yeem ua rau xeb thiab xeb.
Kev pabcuam lub neej yog lwm qhov tseem ceeb uas yuav tsum tau xav txog thaum siv lub hauv paus granite. Lub neej kev pab cuam ntawm lub hauv paus granite yog nyob ntawm nws cov txij nkawm thiab kev siv. Thaum tswj kom tsim nyog, lub hauv paus granite tuaj yeem nyob tau ntau xyoo, txawm tias mus txog lub neej. Granite paub tias muaj zog tiv taus hnav thiab tsim kua muag piv rau lwm cov ntaub ntawv xws li hlau, uas yuav tsum tau saib xyuas tas li thiab hloov.
Nws yog ib qho tsim nyog sau cia tias cov hauv paus granite tsis tas yuav hloov pauv. Tsis zoo li lwm cov ntaub ntawv zoo li cov hlau uas cuam tshuam los ntawm xeb thiab xeb uas yuav tsum tau hloov tas li, granite hauv paus muaj zog tiv taus corrosion thiab muaj lub neej ntev. Qhov no txhais tau tias nws tuaj yeem siv tau ntau xyoo yam tsis tas yuav tsum muaj kev saib xyuas tseem ceeb.
Hauv kev xaus, siv lub hauv paus granite rau peb-coordinate ntsuas tshuab yog ib qho kev xaiv zoo heev. Cov khoom ntawm granite uas suav nrog kev hnav tsis kam, ruaj khov, thiab tshuaj lom neeg ua haujlwm txhais tau hais tias nws tuaj yeem kav ntev xyoo yog tias tsim nyog. Kev hloov tsis tu ncua tsis tas yuav tsum tau ua raws li granite muaj zog tiv taus hnav thiab tsim kua muag. Kev tu thiab tu kom zoo ntawm lub hauv paus yog tib yam uas koj yuav tsum tau ua txhawm rau txhim kho nws txoj sia. Yog li, kev siv cov hauv paus granite yog tus nqi tsim nyog nyob rau hauv lub sij hawm ntev, txuag koj los ntawm kev hloov cov nqi uas lwm cov ntaub ntawv xav tau.
