Kev cutter
Txoj kev txiav pub ceev yog siv qhov, feem ntau nyob ntawm kev ua tiav ntawm cov khoom ua tau zoo, kom txhua yam ntawm cov khoom thaum txiav qhov tob yuav tsum muaj cov khoom noj pub ceev, yog tias qhov nrawm dhau, yuav ua rau pob zeb diamond hnav poob, txawm tias ua rau pom blades dhau lawm, yog tias qhov nrawm qis dhau, yuav ua rau cov plaub hau saw cov txheej txheem coj tus kheej tsis tuaj yeem tsis muaj dab tsi, Yog li" blunt, nplua" tsis muaj peev xwm txiav tau. Nyob rau hauv ib txwm muaj xwm txheej, lub cav pub ceev yuav tsum qeeb thaum txiav thiab hnav tsis sib xws thaum pom. Rau cov khoom siv sib xws, thaum txiav qhov tob yog 20mm, cov lus qhia pub zaub mov hauv qab no pom zoo rau koj siv. Thaum cov thickness hloov, qhov txiav ceev tuaj yeem hloov kho raws li qhov chaw txiav (cm2 / min).
