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 mainly determined by factors such as the abrasive material, grain size, binder, hardness, structure, shape, and dimensions. There are many types of grinding wheels.

Grinding wheels, categorized by the abrasive material used, include common abrasives such as corundum and silicon carbide.

The grinding wheels can be categorized by shape into flat wheels, bevel wheels, cylinder wheels, cup wheels, disk wheels, etc.; and by binder into ceramic wheels, resin wheels, rubber wheels, and metal wheels, among others. The key characteristics of the grinding wheels include abrasive material, grain size, hardness, binder, structure number, shape, size, and linear speed.

Since grinding wheels typically operate at high speeds, they should be subjected to a rotation test prior to use (to ensure they will not 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.
