In fact, grinding is often considered a subset of cutting, and vice versa, since each grain of abrasive on a grinding wheel acts like a microscopic, sharp cutting edge that shears a tiny chip from a part surface. In general, precision metal grinding processes are used to remove small amounts of material in order to achieve a particular finish ...

Silicon Carbide Ceramics Description. Silicon carbide (SiC), also known as carborundum or SiC,. is one of the lightest, hardest, and strongest technical ceramic materials. It has exceptional thermal conductivity, resistance to acids, and low thermal expansion. Since the late 19th century, silicon carbide ceramics have been an important material for sandpapers, grinding wheels, and cutting tools.

Grinding/Sanding: Due to UHMW-PE's abrasion resistant properties, grinding and sanding are usually ineffective. In fact, grinding may cause the material to melt and smear, resulting in a clogged grinding wheel. UHMW-PE modified with additives such as glass or metallic oxides will result in shorter tool life.
