Yuav ua li cas cov granite tivthaiv nyob rau hauv lub CMM lav lub sij hawm ntev stability?

Raws li cov cuab yeej precision, kev sib koom tes ntsuas tshuab (CMMs) yuav tsum muaj qhov ruaj khov thiab txhim khu kev qha kom ntseeg tau tias qhov ntsuas tau raug thiab zoo ib yam.Ib qho ntawm cov khoom tseem ceeb uas lav kev ruaj ntseg ntev hauv CMM yog siv cov khoom siv granite.

Granite yog cov khoom siv zoo tshaj plaws rau CMMs vim nws cov yam ntxwv.Nws yog cov pob zeb uas tsis muaj zog nrog cov thermal stability, tsis tshua muaj thermal expansion, tsis tshua muaj dej nqus, thiab siab tawv.Cov khoom zoo no ua rau nws cov khoom ruaj khov heev uas tuaj yeem tiv taus qhov kub thiab txias hloov, kev co, thiab lwm yam ib puag ncig uas tuaj yeem cuam tshuam qhov tseeb ntawm kev ntsuas.

Kub stability yog qhov tseem ceeb hauv CMMs.Cov khoom siv granite siv hauv CMMs muaj cov coefficient tsawg ntawm thermal expansion, txhais tau hais tias nws tsis tshua muaj kev cuam tshuam rau thermal expansion thiab contraction vim qhov kub thiab txias.Txawm hais tias qhov kub thiab txias hloov, granite tuav nws cov duab thiab qhov loj me, kom ntseeg tau tias qhov ntsuas qhov tseeb.

Qhov tawv ntawm granite kuj ua lub luag haujlwm tseem ceeb hauv kev ruaj ntseg ntawm CMMs.Nws yog cov khoom siv tawv thiab ntom ntom, uas txhais tau hais tias nws tuaj yeem txhawb nqa hnyav yam tsis muaj deforming lossis khoov.Qhov tawv tawv ntawm granite tsim cov qauv nruj uas muab lub platform ruaj khov rau lub tshuab.Yog li ntawd, nws txo qhov muaj peev xwm ntawm deformation thaum siv CMM, txawm tias thaum muab cov khoom hnyav.

Ib cag ntawm kev ruaj ntseg ntawm lub cev, granite kuj tiv thaiv tshuaj lom neeg thiab ya raws kev puas tsuaj, uas pab ua kom nws lub neej ntev.Nws tsis cuam tshuam los ntawm ya raws thiab li no yuav tsis xeb, corrode lossis warp, uas tuaj yeem cuam tshuam cov kev ntsuas hauv CMM.Granite kuj tseem tiv taus cov tshuaj feem ntau thiab tsis hnov ​​​​mob nrog lawv.Yog li ntawd, nws tsis zoo li yuav raug puas tsuaj los ntawm cov khoom xws li roj thiab lwm cov kuab tshuaj uas feem ntau siv rau hauv qhov chaw tsim khoom.

Hauv kev xaus, kev siv granite hauv CMMs yog qhov tseem ceeb rau kev ruaj ntseg mus ntev thiab raug.Nws cov khoom tshwj xeeb ua rau nws yog cov khoom siv zoo tshaj plaws rau kev tsim kho ntawm lub hauv paus, ntsuas platform, thiab lwm yam tseem ceeb ntawm CMM.CMMs ua nrog granite muaj qhov ua tau zoo, kev ntseeg tau, thiab rov ua dua, txhawb nqa cov txheej txheem ntau lawm, thiab txhim kho kev tsim khoom tag nrho.Qhov tseem ceeb, granite muab cov khoom tsis sib xws ntawm ib puag ncig, ua rau nws cov khoom zoo tshaj plaws rau kev siv ntau yam kev siv.
