Brown corundum grinding wheels are a main category of abrasive tools used in grinding processes. Grinding wheels are porous bodies made by adding a binder to the abrasive material, followed by pressing, drying, and firing. 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 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 are classified by shape into flat wheels, bevel wheels, cylindrical wheels, cup wheels, and disk wheels, among others; and by binder into ceramic wheels, resin wheels, rubber wheels, and metal wheels, etc. The main characteristic parameters of the grinding wheels include abrasive, grain size, hardness, binder, structure number, shape, size, linear speed, etc.

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 machine vibration during operation). After some time of use, the grinding wheel should be dressed to restore its grinding performance and proper geometric shape.
