1. Lub thickness yog txawv: qhov sib tsoo disc yog tuab, thiab txiav disc yog nyias. Lub thickness ntawm cov txiav disc nrog ib txoj kab uas hla ntawm 100 yog hais txog 1 hli, thaum lub thickness ntawm cov sib tsoo disc nrog ib txoj kab uas hla ntawm 100 yog ntau tshaj 10 hli. Cov hniav txiav yog nyias, kom tsis txhob muaj cov khoom pov tseg tsawg, thiab qhov kev tiv thaiv thaum txiav kuj me me. Yog tias koj siv nws los zom, lub zog yuav siv rau sab, thiab lub thickness ntawm kev sib tsoo disc yuav tawg ib zaug, kom nws tuaj yeem tiv taus lub zog loj. Thaum koj siv nws los txiav, nws yuav tsis txav mus los.
2. Kev siv sib txawv: kev sib tsoo disc yog siv rau kev sib tsoo. Piv txwv li, lub burr ntawm qhov chaw ntawm lub workpiece yuav tsum tau polished, thiab vuam qog nyob rau saum npoo ntawm lub workpiece yuav tsum tau polished. Thaum lub sij hawm no, cov kev sib tsoo disc yog ntsia rau ntawm lub kaum sab xis grinder kom zom tawm cov burr thiab du lub vuam qog; thaum txiav disc yog siv los txiav.
