Tus choj CMM, los yog Coordinate Measuring Machine, yog ib qho khoom siv tau zoo thiab raug siv hauv ntau lub lag luam los ntsuas thiab txheeb xyuas qhov ntev geometric ntawm ntau yam khoom. Lub tshuab yog tsim los ntawm ntau qhov chaw ua los ntawm cov khoom sib txawv, nrog rau cov khoom siv granite uas yog qhov tseem ceeb hauv kev muab kev ruaj ntseg thiab rigidity rau lub tshuab.
Granite yog qhov zoo dua rau kev ua choj CMM qhov chaw vim nws qhov kev ruaj ntseg zoo heev, siab tawv, thiab ntuj damping zog. Cov khoom no pab muab lub platform ruaj khov rau kev ntsuas kom raug thiab txo qis qhov cuam tshuam ntawm kev vibrations uas yuav cuam tshuam rau qhov ntsuas qhov tseeb. Txawm li cas los xij, txawm tias muaj txiaj ntsig zoo ntawm granite, cov khoom yuav raug hnav thiab tsim kua muag thiab yuav tsum tau hloov tom qab qee lub sijhawm.
Lub voj voog hloov ntawm granite qhov hauv choj CMM nyob ntawm ntau yam, nrog rau kev siv ntau zaus, ib puag ncig, thiab qhov zoo ntawm granite siv hauv kev tsim khoom. Kev lag luam-txheej txheem hloov lub voj voog rau granite qhov feem ntau yog nyob nruab nrab ntawm tsib mus rau kaum xyoo, txawm hais tias lub sijhawm no yuav txawv nyob ntawm qhov ua ntej.
Txhawm rau ua kom pom kev ua haujlwm zoo ntawm lub tshuab, kev saib xyuas tsis tu ncua thiab ntsuas qhov ntsuas yog qhov tsim nyog, thiab cov xwm txheej ntawm cov granite yog qhov tseem ceeb ntawm qhov no. Kev tshuaj xyuas tsis tu ncua thiab tu ntawm granite qhov chaw yog qhov tseem ceeb los xyuas kom meej lawv lub neej ntev thiab kev ua haujlwm zoo. Tsis tas li ntawd, ib qho kev puas tsuaj lossis hnav ntawm cov khoom granite yuav tsum tau tuaj koom tam sim ntawd kom tsis txhob muaj kev cuam tshuam loj rau kev ntsuas qhov tseeb.
Hauv kev xaus, kev siv cov khoom siv granite hauv choj CMM muab ntau yam txiaj ntsig, suav nrog qhov raug siab thiab ntsuas kev ruaj ntseg. Txawm hais tias cov khoom yuav raug hnav thiab tsim kua muag los ntawm kev siv ntau zaus, kev saib xyuas kom zoo thiab kev hloov pauv tuaj yeem ua kom muaj kev ua haujlwm ntev thiab pom qhov tseeb. Kev lag luam tus qauv hloov lub voj voog ntawm granite qhov chaw hauv choj CMM yog nyob nruab nrab ntawm tsib mus rau kaum xyoo, nyob ntawm seb cov xwm txheej tau teev tseg saum toj no. Yog li ntawd, kev tshuaj xyuas tsis tu ncua, tu, thiab hloov cov khoom no yog qhov tseem ceeb ntawm kev ua kom muaj kev ua haujlwm siab thiab txhim khu kev qha CMM.
