Rau cov cuab yeej precision cov cuab yeej hauv paus, li cas Granite piv rau lwm cov ntaub ntawv, xws li hlau lossis txhuas?

Granite Precision: lub hauv paus ntawm cov khoom siv precision piv rau cov hlau thiab aluminium

Rau cov cuab yeej siv precision cov cuab yeej, cov khoom xaiv yog qhov tseem ceeb rau kev ua kom tau tseeb thiab ruaj khov. Granite tau ntev tau xaiv ntev rau cov cuab yeej siv ua ntej vim nws cov khoom zoo tshaj, tab sis nws piv rau cov hlau lossis txhuas?

Granite yog paub rau nws cov khoom siv ruaj khov thiab kev co-damping cov khoom, ua rau nws cov khoom zoo tshaj plaws rau lub hauv paus khoom siv ntsuas. Nws qhov chaw ntom ntom ntom thiab cov hws khov kom muaj kev nthuav dav thiab kev cog lus, muab lub hauv paus ruaj khov rau cov khoom siv thev naus laus zis. Ib qho ntxiv, cov granite muaj qhov ua tau zoo heev rau corrosion thiab hnav, ua kom lub sijhawm ntev ntev thiab kev ntseeg tau.

Nyob rau hauv sib piv, steel thiab txhuas kuj muaj lawv tus kheej thiab txwv. Hlau yog paub rau nws lub zog thiab rigidity, ua nws haum rau cov ntawv thov hnyav. Txawm li cas los xij, cov hlau muaj kev cuam tshuam ntau dua rau cov khoom nthuav dav thiab kev cog lus, uas tuaj yeem cuam tshuam qhov tseeb ntawm lub cuab yeej. Aluminium, ntawm qhov tod tes, yog lub teeb yuag thiab muaj cov thermal zoo conductivity, tab sis nws kuj yuav tsis muab cov theem sib luag thiab kev co damping li granite.

Thaum txiav txim siab piv granite, hlau, thiab txhuas rau cov cuab yeej siv precision cov khoom siv, nws yog ib qho tseem ceeb los ntsuas qhov kev xav tau ntawm daim ntawv thov. Rau cov ntawv thov uas ruaj khov, kev co damping thiab tsawg heev thermal expansion yog qhov tseem ceeb, granite yog qhov kev xaiv zoo tshaj plaws. Nws cov khoom siv tsis sib xws thiab ruaj khov ua rau nws cov khoom siv ntawm kev xaiv ua si hauv kev lag luam xws li metrology, thiab tshuaj xyuas kho kom zoo nkauj, thiab tshuaj xyuas kho dua tshiab.

Hauv cov ntsiab lus, thaum hlau thiab txhuas txhua qhov muaj txiaj ntsig zoo, Granite yog qhov kev xaiv zoo tshaj plaws rau lub hauv paus cov khoom siv ntsuas. Nws qhov kev ruaj khov zoo tshaj plaws, kev co damping cov zog thiab ua rau thermal hloov ua kom nws cov khoom siv ntawm kev ntsuas tseem ceeb tshaj plaws hauv cov ntawv thov tseem ceeb. Thaum precision yog qhov tseem ceeb, granite precision cov cuab yeej siv hluav taws xob muab tsis muaj kev ua tau zoo thiab kev ntseeg tau.
