Txiav discs yog cov sib tsoo log, uas yog cov ntawv nyias ua los ntawm cov abrasives thiab binder resins rau txiav cov hlau zoo tib yam, cov hlau tsis muaj hlau, thiab cov khoom tsis yog xim hlau. Lawv muab faib ua cov pob zeb txiav discs thiab pob zeb diamond txiav discs.
Siv cov iav fiber ntau thiab cob ua cov ntaub ntawv txuas ntxiv, nws muaj zog tensile, cuam tshuam, thiab khoov lub zog, thiab yog siv dav hauv kev tsim thiab txiav cov hlau zoo tib yam, cov hlau tsis muaj hlau, thiab cov khoom tsis yog hlau. Cov ntaub ntawv zoo heev thiab kev ua haujlwm zoo tshaj plaws ua kom muaj kev ua haujlwm siab thiab kev pom kev lag luam zoo rau cov khoom ua haujlwm ua los ntawm cov khoom sib txawv.
