Yog vim li cas rau qhov tsis muaj zog ceev ntawm pob zeb polishing tshuab

Rau polishing tshuab, rotational ceev thiab kev sib txhuam (polishing) quab yuam yog cov xwm txheej rau kev sib piv ntawm ob lub ntsiab lus:
1. Kev kub ceev, tsis tshua muaj kev sib txhuam, kev sib txuas lus, kev sib txhuam qis, ceev ceev
2. Kev nrawm nrawm thiab kev sib txhuam siab, thiab rov ua dua;
Yog li tus yuam sij rau kev daws qhov teeb meem no yog thawj zaug txiav txim siab seb yuav tsum tau siv zog npaum li cas los hloov thiab hloov ceev thaum lub sijhawm ua haujlwm, kho qhov tsim nyog ceev kom ua tiav polishing ib txwm, txwv tsis pub cov iav sab hauv yuav tsum tau hloov, thiab cov tshuab polishing me me yuav muaj cov iav ruaj khov uas tsis tuaj yeem hloov ceev.
