Raws li machined, raws li lub npe qhia, yog qhov chaw tsim thaum lub sij hawm tsim khoom.Thaum qhov chaw tsis muaj qhov yuav tsum tau ua kom tiav qhov chaw ntxiv thiab tuaj yeem ua haujlwm nrog qhov chaw muaj cai tom qab kev tsim khoom, qhov txheej txheem saum npoo tiav yog xaiv.Raws li machined tas muaj me ntsis kom tsis muaj ntxiv machining ua rau ib feem tom qab ntau lawm.

Peb cov txheej txheem nto tiav yuav tsum tau tshem tawm thiab deburring.Qhov nto roughness muaj tom qab machining yog 3.2 μm (126 μin).Raws li machined nto yuav pom cov cim thiab nto imperfections ua thaum lub sij hawm machining.Txij li nws yog tus txheej txheem tiav, kev kho kom zoo nkauj ntxiv tsis muaj nrog nws.
