Cov khoom siv twg zoo dua rau kev siv tshuab ua kom raug: hlau cam khwb cia lossis granite?

Peb pab neeg ua haujlwm engineering tau ua qhov kev sim sib piv kev ua tau zoo thoob plaws thiab tob tob rau cov khoom siv ua los ntawm hlau cam khwb cia thiab granite, nrog rau tag nrho kev ntsuam xyuas ua raws li cov qauv ib puag ncig nruj ntawm cov chaw tsim khoom siv hauv chav huv. Tom qab kev tshuaj xyuas cov ntaub ntawv thiab kev txheeb xyuas qhov tseeb, pab neeg tau xaus lus meej tias granite ua haujlwm zoo tshaj plaws thiab nyiam siv rau kev ua cov khoom siv optical component siab heev, kev tshuaj xyuas semiconductor wafer nrog rau cov xwm txheej ua haujlwm siab heev nano-scale precision machining.
Cov khoom siv hlau cam khwb muaj ntau yam tsis zoo uas txwv tsis pub ua haujlwm ntau. Nws muaj qhov coefficient ntawm thermal expansion siab thiab tsis muaj zog tiv thaiv kev co; lub sijhawm ntawd, nws yooj yim rau xeb ntawm qhov chaw thiab txuas ntxiv poob cov hlau me me thaum lub sijhawm ua haujlwm ntev. Txawm tias qhov kub thiab txias me ntsis yuav ua rau cov hlau cam khwb tsis zoo, ua rau muaj qhov sib txawv ntawm cov khoom siv. Ntxiv mus, cov hlau me me thiab cov xeb seem yuav ua rau cov khoom siv precision tsis zoo, ua rau muaj kev phom sij zais rau qhov zoo ntawm cov khoom. Ntawm qhov tsis sib xws, granite muaj cov yam ntxwv zoo tshaj plaws ntawm lub cev: nws muab qhov nrawm thermal nthuav dav qis heev thiab kev ua haujlwm zoo kawg nkaus ntawm kev nqus kev co, uas tuaj yeem cais cov kev cuam tshuam sab nraud thiab zam kev sib tham ntawm kev ua haujlwm. Tsis tas li ntawd, granite yog ntuj tsis muaj hlau nplaum thiab tsis muaj xeb kiag li. Tom qab kev kho saum npoo, nws tuaj yeem ua tiav cov kev cai nruj ntawm cov plua plav thiab tsis muaj kuab paug ntawm cov chav huv. Cov granite zoo tuaj yeem ua kom ruaj khov Class 00 ultra-high flatness rau ntau xyoo khiav, txo qhov zaus ntawm cov khoom siv kaw rau kev rov kho dua thiab txhim kho kev ua haujlwm ntau lawm.
Yuav tsum lees tias, cov hlau cam khwb cia muaj qee qhov zoo thaum siv rau cov txheej txheem ua haujlwm hnyav nrog cov kev cai tsis tshua muaj kev ntsuas. Txawm li cas los xij, nws cov khoom tsis zoo ua rau nws tsis ua tau raws li qhov yuav tsum tau ua ntawm qib micron ntawm kev tsim khoom siv high-precision. Txij no mus, peb lub tuam txhab yuav ua kom nrov thiab ua tus qauv rau cov hauv paus granite rau txhua hom kev ua thiab kuaj cov khoom siv hauv cov chaw ua haujlwm huv si. Peb kuj tseem yuav siv cov lus qhia kev tiv thaiv thiab kev saib xyuas rau cov hauv paus granite, npog tag nrho rau sab nano dej thiab tiv thaiv kev ua qias tuaj, rov ua dua tus neeg sawv cev txhua ib mus rau ob xyoos, thiab saib xyuas thiab tswj qhov kub thiab av noo ntawm lub chaw ua haujlwm tas li. Kev txhim kho cov khoom siv thiab kev tswj hwm tus qauv no yuav ua rau kev ua haujlwm ntev ntawm cov khoom siv precision, ua kom lub voj voog kev pabcuam ntawm cov hauv paus granite ntev dua, thiab ua kom cov khoom tiav tiav muaj txiaj ntsig zoo, tsim lub hauv paus kho vajtse ruaj khov rau lub tuam txhab kev tsim khoom siv high-end ultra-precision.kev txhim kho lag luam.
