Kupedzwa kwakatsetseka kwakagadzirwa kunoburitsa nzvimbo ine arithmetic zvinoreva roughness, inozivikanwawo seRa, ye1.6 μm (63 μin).Senge sekupedzisa kwemuchina, kupedzisa kwakatsetseka kunopa kwakapinza kumucheto kubviswa uye kubvisa kwechikamu.Sezvo nzvimbo yacho yakatsvedzerera pane yakajairwa yekupedzisa nzvimbo, mamakisi nekusakwana hazvinyanyi kuoneka.Yakagadzirwa yakatsetseka kupera haiwanikwe ine cosmetic kupera.

Zvimwe zvikamu zvinoda kupera kwakapfava kupfuura iyo inopihwa neyakajairwa kupera.Mumamiriro ezvinhu akadaro, imwe yekuwedzera machining oparesheni inoitwa kuti kuderedze kushata kwepamusoro kune kukosha kunogamuchirwa.Muzvikamu zvinogadzirwa nemichina yeCNC, mashandiro akadai anogona kazhinji kuwedzerwa kumaitiro ekugadzira kuchengetedza nguva.Kune zvikamu zvinogadzirwa neasiri-CNC michina kana akawanda michina, CNC machining inoshandiswa kune yakatsetseka machining mushure mekugadzirwa kwapera uye chikamu chagadzirira.
