Hiomakappaleet, commonly referred to as grinding wheels, are abrasive tools used for grinding operations. They consist of abrasive grains bonded together by a binder material. The abrasive grains are the cutting elements, while the binder holds them in place and determines the wheel's overall structure and hardness. Various types of abrasive materials are used, including aluminum oxide, silicon carbide, and diamond, chosen based on the material being ground and the desired finish.

Grinding wheels are manufactured in a wide range of shapes and sizes to suit different applications, such as cutting, shaping, sharpening, and polishing. The selection of a grinding wheel involves considering factors like grain size, grit, grade (hardness), structure (density of grains), and bond type. These parameters are critical for achieving efficient material removal, desired surface finish, and optimal wheel life.

The use of grinding wheels requires proper safety precautions. This includes wearing appropriate personal protective equipment, such as safety glasses or face shields, and ensuring the grinding wheel is securely mounted and operates at the correct speed. Regular inspection for damage or wear is also essential to prevent accidents. When the abrasive grains become dull, the wheel is considered "loaded" or "glazed," and it either needs to be dressed to expose fresh abrasive or replaced.
