Brown corundum grinding wheels are a major 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 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 grinding wheels are primarily determined by factors such as abrasive material, grain size, binder, hardness, structure, shape, and size. There are many types of grinding wheels.

The abrasive wheels can be categorized into general abrasive wheels (such as corundum and silicon carbide) based on the type of 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 characteristic parameters of the grinding wheels mainly include abrasive, grain size, hardness, bond, structure number, shape, size, and linear speed, etc.

Due to the high-speed operation of grinding wheels, they should be subjected to a rotational 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 in use, grinding wheels should be dressed to restore their grinding performance and correct geometry.
