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 affects the quality, productivity, and economy 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 size. There are many types of grinding wheels.

Grinding wheels, categorized by the abrasive used, include common abrasives like alumina and silicon carbide.

The wheels can be divided into flat grinding wheels, bevel edge grinding wheels, cylindrical grinding wheels, cup grinding wheels, and disk grinding wheels, etc., and can be categorized by binder into ceramic grinding wheels, resin grinding wheels, rubber grinding wheels, and metal grinding wheels, etc. The characteristic parameters of the grinding wheels mainly include abrasive, grain size, hardness, binder, structure number, shape, size, linear velocity, etc.

Due to the high-speed operation of grinding wheels, a reverse rotation test (to ensure the wheel won't crack at high working speeds) and a static balance test (to prevent machine vibration during operation) should be conducted prior to use. After a period of operation, the wheel should be dressed to restore its grinding performance and correct geometry.
