Cov platform yog cov tseem ceeb hauv qhov siab tshaj plaws hauv high - precision kev lag luam, metrology, thiab kuaj cov chaw ib puag ncig. Lawv qhov tshwj xeeb ruaj khov, rigidity, thiab tiv taus mus deformation ua rau lawv cov khoom ntawm kev xaiv rau kev siv qhov twg qhov tseeb yog qhov tseeb. Ib qho ntawm qhov tseem ceeb hauv kev tsim thiab xaiv cov pob zeb pob zeb yog nws cov thickness, uas cuam tshuam ncaj qha rau ob qho laj thawj thiab muaj kev ruaj khov tag nrho.
Kev txiav txim siab qhov tsim nyog tuab ntawm granite precision platform pib nrog kev nkag siab cov kev cia siab thauj khoom thiab ib puag ncig ua haujlwm. Thicker platform ib txwm muaj ntau dua rigidity, txo txoj kev pheej hmoo ntawm kev khoov lossis warping hauv qab qhov hnyav. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv precision machining lossis ntsuas teeb tsa, qhov twg txawm tias microscopic cuam tshuam tau. Conversely, platform uas yog heev yuav tau deflection thaum raug rau qhov hnyav, ua rau muaj qhov tsis muaj tseeb thiab muaj peev xwm ua rau ob qho tib si lub platform thiab cov khoom siv nws txhawb nqa.
Cov kev sib raug zoo ntawm cov tuab, thauj khoom - bearing muaj peev xwm, thiab ruaj khov yog qhov cuam tshuam zoo. Raws li tuab siv zog, lub platform lub sijhawm ntawm inertia- nws tsis kam tiv rau khoov- tseem sawv. Qhov no txhais tau tias nws tuaj yeem txhawb cov khoom ntim ntau dua tsis muaj kev sib deev ncaj ncees lossis meej. Txawm li cas los xij, cov tuab yuav tsum tau sib npaug nrog cov kev txiav txim siab zoo xws li kev thauj, kev teeb tsa, thiab tus nqi. Cov platform tuab dhau yuav dhau los ua cumbersome, thaum lub lim dej uas yog nyias nyias kev pheej hmoo thiab kev hnav kom nrawm dua. Tsis tas li ntawd, cov granite cov khoom siv, xws li ntom ntom, Elfastic Modulus, thiab sab hauv lub luag haujlwm tseem ceeb hauv kev txiav txim siab optimal tuab rau daim ntawv thov.
Cov kws tshaj lij kev lag luam feem ntau ua ke nrog cov qauv kev tshawb fawb nrog cov kev tsom xam cov ntsiab lus zoo los xam cov tuab zoo tshaj. Cov hau kev no rau kev xa khoom, cov ntaub ntawv ntev, thiab cov ntaub ntawv tshwj xeeb, txawm tias nws muaj kev ntsuas cov kev ntsuas lossis kev ua haujlwm zoo ntawm kev ua haujlwm. Cov tuab tuab kom zoo kom cov platform uas lub platform tswj lub ntsej muag zoo kawg nkaus, txo qis kev co thiab kev tswj cov raug rau cov haujlwm muaj peev xwm.
Hauv cov ntsiab lus siv tswv yim, xaiv txoj cai granite platform Thickness tsis yog tsuas yog muaj teeb meem ntawm kev txhawb nqa phaus {}}}}}}}}}}}}}}. Ib qho zoo -}}}}}}}}}}}}}}} qhov kev ua tau zoo maximizes lub platform kev ua yeeb yam, thiab ua kom cov haujlwm txhim khu kev qha txawm tias muaj kev lag luam xav tau. Los ntawm kev saib xyuas cov khoom uas yuav tsum tau ua, thiab cov khoom siv, cov kws txua cov khoom siv tau xaiv cov khoom ruaj khov, qhov tseeb, thiab kav ntev.
