Brown corundum grinding wheels are a major category of abrasive tools in grinding processes. 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 properties of grinding wheels vary greatly, which have a significant impact on the processing quality, productivity, and economy of grinding. The properties 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.

Grinding wheels can be categorized into standard abrasives (such as corundum and silicon carbide) based on the abrasive material used.

The grinding wheels can be categorized by shape into flat grinding wheels, bevel grinding wheels, cylindrical grinding wheels, cup grinding wheels, and disk grinding wheels, among others; and by bond type into ceramic grinding wheels, resin grinding wheels, rubber grinding wheels, and metal grinding wheels, etc. The main characteristic parameters of grinding wheels include abrasive, 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 rotational 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 proper geometric shape.
