Brown corundum grinding wheels are a major category of abrasive tools used in machining processes. Grinding wheels are porous bodies made by adding a binder to the abrasive material, followed by molding, drying, and firing. Due to the differences in abrasive material, binder, and manufacturing processes, the characteristics of grinding wheels vary greatly, which has a significant impact on the processing quality, production efficiency, and cost-effectiveness of grinding. The characteristics of grinding wheels are primarily 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 used, include common abrasives such as corundum and silicon carbide.

The grinding wheels can be categorized by shape into flat wheels, bevel-edged 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 characteristic parameters of the grinding wheels mainly include abrasive material, grain size, hardness, bond, structure number, shape, size, and linear speed.

Due to the high-speed operation of grinding wheels, they should be subjected to a rotation test prior to use (to ensure they won't crack at high working speeds) and a static balance test (to prevent vibration during operation). After operating for a period, grinding wheels should be trued to restore their grinding performance and proper geometric shape.
