Brown corundum grinding wheels are a major category of abrasive tools used in grinding processes. A grinding wheel is a porous body made by adding a binder to the abrasive material, followed by pressing, drying, and baking. Due to the differences in abrasive material, binder, and manufacturing processes, the characteristics of grinding wheels vary greatly, which significantly impacts the quality, productivity, and cost-effectiveness of the grinding process. The characteristics of a grinding wheel are primarily determined by factors such as the abrasive material, grain size, binder, hardness, structure, shape, and size. There are many different types of grinding wheels.

Common abrasive wheels, such as those made from corundum and silicon carbide, are categorized by the abrasive material used.

The abrasive wheels can be classified by shape into flat wheels, bevel wheels, cylindrical wheels, cup wheels, and disc wheels, etc.; and by binder into ceramic wheels, resin wheels, rubber wheels, and metal wheels, etc. The characteristic parameters of the abrasive wheels mainly include abrasive material, grain size, hardness, binder, structure number, shape, size, and linear speed, etc.

Due to the high-speed operation of grinding wheels, they should be subjected to a rotation test (to ensure they won't crack at high working speeds) and a static balance test (to prevent vibration during operation). After a period of use, the grinding wheel should be dressed to restore its grinding performance and correct geometry.
