What is a Cup whetstone / Cup Grinding Wheel?

A cup grinding wheel is an abrasive tool used for grinding operations, characterized by its circular cup-shaped design. The surface of the wheel is embedded with abrasive grains, making it ideal for shaping, finishing, or smoothing surfaces of hard materials such as metals and ceramics. Cup grinding wheels are particularly suitable for flat surface grinding and groove finishing, offering fast grinding speeds and uniform results.

They are widely used in industrial applications such as construction, engineering, tool manufacturing, and automotive parts processing. Depending on the material and purpose, diamond, CBN (cubic boron nitride), or alumina materials are selected. With high durability and precision, cup grinding wheels significantly enhance productivity.
