(1) tsis tshua muaj machining theem. Kev txiav tawm ntawm feem ntau ntawm kev siv machining ntawm txhua qhov kev ua haujlwm, thiab kev ua cov txheej txheem raug raug, qhov kev xav tseem ceeb yog nce tus nqi noj ntau li ntau tau.
(2) Kev ua tiav ib theem. Txiav cov kev tsis xws uas yuav tshwm sim tom qab ntxhib machining, npaj rau cov xov ntawm npoo, thov kom muaj qee qhov kev ua tiav ntawm qhov ua tiav, xyuas kom meej qhov tsim nyog ntawm qhov tau ua tiav, thiab ua tiav kev ua tiav ntawm cov theem ob.
(3) Cov theem tiav. Nyob rau qib no, kev txiav loj ntawm qhov nrawm, qhov chaw pub khoom noj me me thiab qhov txiav txiav qhov tob tau siv los txhawm rau tshem cov nyiaj tiav tas los ntawm cov txheej txheem dhau los, kom cov ntsej muag pom ntawm qhov tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev kos duab.
(4) Cov theem ua tiav zoo tiav. Nws yog tsuas yog siv los txo qhov saum npoo roughness tus nqi los yog ntxiv dag zog rau qhov chaw ua, thiab feem ntau yog siv rau txheej txheem saum npoo nrog qhov siab yuav tsum ua kom zoo rau saum npoo (ra≤0.32 μm).
(5) Ultra-zoo ua theem. Qhov ua tiav raug yog 0.1-0.01μm, thiab qhov saum npoo roughness tus nqi ra yog tsawg dua lossis sib npaug 0.001μm. Cov txheej txheem tseem ceeb yog: zoo txiav, nplua iav iav sib tsoo, nplua sib tsoo thiab polishing.
