Hnub no kuv qhia rau koj txog cov txheej txheem ntawm precision mechanical qhov chaw.
Precision qhov kev ua tsis tuaj yeem ua kom tiav tag nrho cov txheej txheem ua tiav ntawm txhua qhov chaw hauv ib txheej txheem, thiab tag nrho cov txheej txheem ntawm precision qhov kev ua tiav tuaj yeem muab faib ua cov theem hauv qab no.
(1) Roughing theem. Txiav tawm feem ntau ntawm machining nyiaj pub dawb ntawm txhua qhov chaw ua haujlwm, thiab kev ua tiav ntawm cov qauv ntsuas qhov tseeb, qhov kev txiav txim siab tseem ceeb yog ua kom cov khoom tsim tau ntau li ntau tau.
(2) Semi-finishing theem. Txiav tawm qhov tsis xws luag uas yuav tshwm sim tom qab machining ntxhib, thiab npaj rau kev ua tiav ntawm qhov chaw, xav tau qee qhov kev ua haujlwm raug thiab ua kom muaj qhov tsim nyog ua tiav, thaum ua tiav cov machining ntawm qhov chaw thib ob.
(3) Ua tiav theem. Nyob rau hauv cov theem no siv ib tug loj txiav ceev, me me pub thiab qhov tob ntawm kev txiav, tshem tawm cov xov paj sab laug los ntawm cov txheej txheem dhau los, kom lub nto ntawm ib feem kom tau raws li cov kev cai ntawm daim duab.
(4) theem tiav. Feem ntau yog siv los txo tus nqi deg roughness los yog ntxiv dag zog rau qhov chaw machined, feem ntau yog rau saum npoo roughness yuav tsum siab heev (ra Tsawg dua los yog sib npaug rau 0.32 μm) nto ua.
(5) Ultra-precision machining theem. Machining raug nyob rau hauv 0.1-0.01 μm, nto roughness tus nqi ra Tsawg dua los yog sib npaug rau 0.001 μm ua theem. Cov txheej txheem tseem ceeb yog: precision txiav, zoo iav sib tsoo, precision sib tsoo thiab polishing, thiab lwm yam.
