Brown corundum grinding wheels are a major category of abrasive tools used in grinding operations. A grinding wheel is a porous body 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 a grinding wheel 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 can be categorized into ordinary abrasive types, such as those made of corundum 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., based on shape; and into ceramic grinding wheels, resin grinding wheels, rubber grinding wheels, and metal grinding wheels, etc., based on binder. The main characteristic parameters of the grinding wheels include abrasive, grain size, hardness, binder, structure number, shape, size, and linear speed, etc.

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