The grinding wheel is composed of glass powder (binder) and abrasive (alumina, silicon carbide, etc.). Mix them together and weigh them into a steel mold. The mixture is squeezed under a certain pressure and then pressed out of the mold. Then it is placed in a furnace and the binder melts when the temperature reaches 1050 ℃.

A grinding wheel is a circular and accurate tool made by mixing thousands of sharp abrasive particles with a binder.

The 8 technical requirements for selecting grinding wheels include process stability, quantity of grinding materials, grinding wheel cost per part, grinding surface quality (roundness, shape, and roughness), cycle time required for grinding parts, lifespan of the entire grinding wheel, frequency of grinding wheel replacement, and grinding wheel replacement time.
