Precision qhov kev ua tsis tuaj yeem ua kom tiav tag nrho cov txheej txheem ua tiav hauv ib txheej txheem, tag nrho cov txheej txheem ntawm kev ua tiav cov txheej txheem tuaj yeem muab faib ua cov theem hauv qab no.
1, roughing theem. Txiav tawm feem ntau ntawm cov nyiaj machining ntawm txhua qhov chaw ua haujlwm, thiab kev ua haujlwm tawm ntawm kev siv zoo, qhov kev txiav txim siab tseem ceeb yog txhawm rau txhim kho cov khoom tsim tau ntau li ntau tau.
2, Semi-tiav 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 cov npoo tiav tiav, thaum ua tiav cov machining ntawm qhov chaw thib ob.
3, Ua tiav theem. Nyob rau theem no, kev siv cov kev txiav loj loj, me me pub thiab qhov tob ntawm kev txiav, tshem tawm cov npoo npoo sab laug los ntawm cov txheej txheem dhau los, kom lub npoo ntawm ib feem kom ua tau raws li cov kev cai ntawm kev kos duab.
4, Lub teeb tiav theem. Feem ntau yog siv los txo tus nqi deg roughness lossis ntxiv dag zog rau cov txheej txheem ua tiav, feem ntau yog rau cov txheej txheem roughness siab heev (ra Tsawg dua lossis sib npaug rau 0.32μm) nto ua haujlwm.
5, Ultra-precision machining theem. Machining raug nyob rau hauv 0 1-0 01μm, nto roughness tus nqi ra Tsawg dua los yog sib npaug rau 0.001μm ua theem. Cov txheej txheem tseem ceeb yog: precision txiav, zoo iav sib tsoo, precision sib tsoo thiab polishing, thiab lwm yam.
