The abrasive particles of the ceramic grinding medias are held in the ceramic binder. Ceramic grinding medias are generally used for hard metal grinding and cut-off corner. Ceramic grinding medias are denser and harder compared to plastic medias. It is especially used in deburring, rust removal, degreasing, descaling, cut-off corner, oxide opening processes of steel alloys. There are ceramic stones in many different geometries, sizes and grinding levels.
