Surface Grinder - Types of Grinders & How They Work

The grinding wheel acts as the cutting tool on a surface grinder. Unlike a lathe, drilling, or milling machine, the cutting tool on a grinder doesn't produce curled chips. Instead, the abrasive particles on the periphery and/or the face of the grinding wheel peels off a small amount of material in the form of fine metal dust.

The Difference Between Grinding and Cutting
