1. Txoj hauv kev kom tsis txhob muaj cov cuab yeej sib tsoo yog hooped:
Siv cov kab noj hniav tshwj xeeb.
Nyob rau hauv cov txheej txheem ntau lawm, feem ntau kom txiav ntse, demagnetization.
Nthuav cov kab noj hniav.
Xaiv cov abrasives nrog cov hniav sloped es tsis yog cov tiaj tus.
2. Cov laj thawj tseem ceeb rau kev puas tsuaj sai ntawm lub hauv paus tuag yog:
Abrasive clearance yog me me. Nws yog feem ntau pom zoo tias tag nrho cov kev tshem tawm ntawm abrasive yog 20 feem pua 20 feem pua ntawm cov tuab ntawm raw cov ntaub ntawv.
Convex thiab concave abrasives rau qaug zog acid tsis zoo, xws li tuag puag, abrasive qhia qhov chaw, CNC punch hniav raug tsis txaus.
Tuag lub hauv paus kub yog siab dhau lawm, qhov tseem ceeb yog vim li cas tib lub cuab yeej sib tsoo rau lub sijhawm ntev ua rau lub punch kub dhau.
