Granite Precision: Lub hauv paus ntawm cov khoom siv precision piv rau hlau thiab txhuas

Rau cov khoom siv precision, kev xaiv cov khoom siv yog qhov tseem ceeb rau kev ua kom raug thiab ruaj khov. Granite tau ntev los ua qhov kev xaiv nrov rau cov khoom siv precision vim nws cov khoom zoo dua, tab sis nws piv rau lwm cov ntaub ntawv xws li hlau lossis txhuas li cas?

Granite paub txog nws qhov kev ruaj khov zoo heev thiab cov khoom siv tiv thaiv kev co, ua rau nws yog cov khoom siv zoo tshaj plaws rau lub hauv paus ntawm cov khoom siv precision. Nws qhov siab ceev thiab porosity qis ua kom muaj kev nthuav dav thermal tsawg kawg nkaus thiab contraction, muab lub hauv paus ruaj khov rau cov tshuab precision. Tsis tas li ntawd, granite muaj kev tiv thaiv zoo heev rau corrosion thiab hnav, ua kom ntseeg tau tias muaj kev ruaj khov thiab kev ntseeg siab mus sij hawm ntev.

Nyob rau hauv kev sib piv, hlau thiab txhuas kuj muaj lawv tus kheej zoo thiab kev txwv. Hlau yog lub npe hu rau nws lub zog thiab rigidity, ua rau nws haum rau cov ntawv thov hnyav. Txawm li cas los xij, hlau yog yooj yim dua rau thermal nthuav dav thiab contraction, uas tuaj yeem cuam tshuam rau qhov tseeb ntawm lub cuab yeej. Aluminium, ntawm qhov tod tes, yog lub teeb thiab muaj thermal conductivity zoo, tab sis nws yuav tsis muab tib theem ntawm kev ruaj khov thiab kev co damping li granite.

Thaum xav txog kev sib piv granite, hlau, thiab txhuas rau cov khoom siv precision, nws yog ib qho tseem ceeb kom soj ntsuam cov kev cai tshwj xeeb ntawm daim ntawv thov. Rau cov ntawv thov uas qhov ruaj khov, kev co damping thiab qhov tsawg kawg nkaus thermal nthuav dav yog qhov tseem ceeb, granite yog qhov kev xaiv zoo tshaj plaws. Nws qhov tseeb thiab kev ruaj khov tsis muaj qhov sib piv ua rau nws yog cov khoom siv xaiv rau cov khoom siv precision hauv kev lag luam xws li metrology, semiconductor manufacturing, thiab optical inspection.

Hauv kev xaus lus, thaum hlau thiab txhuas muaj lawv qhov zoo, granite yog qhov kev xaiv zoo tshaj plaws rau lub hauv paus ntawm cov khoom siv precision. Nws qhov kev ruaj khov zoo heev, cov khoom siv damping vibration thiab kev tiv thaiv rau kev hloov pauv thermal ua rau nws yog cov khoom siv xaiv los xyuas kom meej qhov siab tshaj plaws hauv cov ntawv thov tseem ceeb. Thaum qhov kev ua tau zoo yog qhov tseem ceeb, granite precision khoom siv hauv paus muab kev ua tau zoo thiab kev ntseeg siab tsis tau sib piv.
