Nyob rau hauv high -} kawg semiconductor raug,precision tsis yog tsuas yog hais txog qhov ntev - nws yog txog qhov kub thiab txiasCov. Raws li tshuab ua kom tau txoj kev mus cuag micrometer theem,Txawm tias muaj cua sov me me -}} indicts distortionstuaj yeem muaj lub txim tseem ceeb ntawm ib feem ua haujlwm, tshwj xeeb hauv cov khoom siv xws liKho qhov muag lub lens mounts, Ultra - precision ntxaiv, lossisKev sib ncag theem.
Tus txiv neej zais: cua sov -}} inducte distortion
Thaum lub sij hawm cnc machining, tshwj xeeb yog thaum muaj kev kub ceev lossis thaum ua haujlwm nrog cov hlau ua haujlwm lossis cov khoom sib xyaws, tshav kub tsis tu ncua. Qhov hluav taws xob thermal no, yog tias tsis tswj hwm, tuaj yeem:
Kev komNrov nthuav davnyob rau hauv workpiece
Ua rauTool Deflectionlos yog tsis sib haum txiav
NtxiasCov duab ua kom nrujTom qab txias
Xav txog cov khoom sib xyaw ua ke zoo li ibOVERCER LENDER DOLDERsiv hauv photolithography cov tshuab. Qhov kev sib txawv me me ntawm txawm 2-3 microns tuaj yeem pov tawm tag nrho cov kev kho kho kho kho qhov muag, txo cov txiaj ntsig ntawm ntau txhiab tus chips.
Vim Li Cas Tshuab Machining Luv Luv
Hauv kev sib chaws machining ib puag ncig,Coolant Flow, Tshuab Qhov Kub Zaum Kub, thiabCov huab cua ambientYog tsis tshua pom qhov optimized rau sub - micron micron tseeb. Tab sis nyob rau hauv cov txheej txheem semiconductor, qhov no tseem ceeb. Piv txwv li:
Qhov kub hloov ntawm tsuas yog 1℃tuaj yeem ua rau aluminium kom nthuav ntawm ntau dua 20 μm rau
Tsis sib xws spindle tshav kub tuaj yeem ua rau kev txiav txoj kev drift
Residual Tshav Kub Kub Tsim Nyob rau hauv nyias -}}}}}} {}> Machining
Peb Txoj Kev Ua: Precision Pib nrog Thermal Stability
NtawmNpis Xus Precision, peb txoj kev tswj thermal ua ib feem ntawm pebCov txheej txheem tswj me me, tsis yog tom qab tom qab:
Kev siv ntawmThermally Cov Cuab Yeej Siv Hluav Taws Xobthiabkub -} tswj ib puag ncig
Kev nqis tes uaTsawg - Kev Kub Ceev Tej Cov Tshiab, suav nrog kev yoog raws
Tiag - lub sijhawmHauv - txheej txheem ntsuas kubRau cov haujlwm tseem ceeb
Kev siv tswv yim ntawmNtau -} pagenrog cov kauj ruam yooj yim
QHOV TSEEB: Machining Ultra - precision ntxaiv rau optical tshuab
Ib tus neeg xav tau ntxaiv vaj tsev nrogDaim ntawv hauv qab hauv 2 μmRau siv nyob rau hauv lub siab - ceev ceev kev soj ntsuam cuab yeej. Thawj cov tshuaj tiv thaiv ua tsis tiav vim yog kev mob me. Peb tau hloov peb txoj hauv kev kom suav nrogcuam tshuam rouging, ncua sijhawm so, thiab tshaj tawm - tshuab divilization. Qhov tshwm sim? Kev ua tau zoo sib xws nyob hauv ntau qhov chaw khiav.
Thaum precision nyob ntawm seb qhov kub thiab txias, peb npaj txhij
Yog tias koj cov phiaj xwm xav tau uasua nyob rau hauv tiag - ntiaj teb cov xwm txheej - tsis yog rau lub tshuab, cia peb pab. Peb kev paub hauv kev tswj thermal deformation tswj kom ntseeg tau tias koj lub thev naus laus zis tswj tsis tau tsuas yog thaum lub tshuab machining, tab sisTom qab sib dhos thiab thaum lub sijhawm ua haujlwm.
