Txiav discsyog puag ncig, abrasive cov cuab yeej siv rau kev txiav thiab sib tsoo los ntawm cov ntaub ntawv nyuaj. Lawv txuas nrog cov cuab yeej siv hluav taws xob zoo li lub kaum sab xis thiab muaj cov khoom siv abrasive xws li aluminium oxide lossis silicon carbide txuas rau lub nraub qaum, uas tuaj yeem ua los ntawm cov ntaub ntawv xws li fiberglass lossis resin. Cov discs no yog tsim los rau cov dej num xws li txiav hlau, pob zeb, thiab lwm yam khoom ntom ntom. Lawv tuaj nyob rau hauv ntau yam diameters thiab thicknesses, nrog rau cov qib sib txawv rau cov khoom sib txawv thiab qib ntawm durability. Cov yam ntxwv kev nyab xeeb zoo li cov npoo ntxiv thiab qhov siab tshaj plaws RPM yog qhov tseem ceeb rau kev tiv thaiv kev sib tsoo. Txiav discs yog qhov tseem ceeb hauv kev tsim kho, kev ua haujlwm hlau, thiab lwm yam kev lag luam uas yuav tsum tau txiav kom meej.
