Introduction To Disc & Belt Grinders
What Is a Disc & Belt Grinder?
A disc and belt grinder is a machine equipped with two abrasive surfaces: A flat disc and an endless belt that runs over two rollers. The disc is primarily used for shaping and grinding flat surfaces, while the belt is ideal for contouring and removing material.
Common Uses
- Metalworking: Deburring, shaping, grinding, and polishing metal parts
- Woodworking: Shaping wood, removing material, and preparing surfaces for finishing
