Brown fused alumina grinding wheels are a major type of abrasive tool 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 variations in the abrasive material, binder, and manufacturing process, the characteristics of grinding wheels differ greatly, which has a significant impact on 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, particle size, binder, hardness, structure, shape, and size. There are numerous types of grinding wheels.

Common abrasive wheels (such as corundum and silicon carbide) divided by the abrasive used.

The grinding wheels can be categorized by shape into flat wheels, bevel wheels, cylindrical wheels, cup wheels, and disk wheels, among others; and by bond into ceramic wheels, resin wheels, rubber wheels, and metal wheels, etc. The main characteristic parameters of grinding wheels include abrasive, grain size, hardness, bond, structure number, shape, size, and linear speed, etc.

Since grinding wheels often operate at high speeds, they should be subjected to a rotational test (to ensure the wheel won't crack at high working speeds) and a static balancing test (to prevent vibration during operation) before use. After a period of use, the grinding wheel should be dressed to restore its grinding performance and correct geometry.
