Grinding

Grinding is a service that brings a part to size or finish by abrasive removal. It covers centreless, surface and profile grinding. A Seller grinds to the tolerance and surface the drawing states.

The part is fed past a rotating abrasive wheel. Centreless grinding supports the part on a rest blade between two wheels. Surface grinding holds the part on a magnetic chuck or fixture.

Hardened steel, stainless steel, tool steel and cast iron are often ground. Hardened steel and tool steel are common because they hold shape after heat treatment. Aluminium and brass can be ground but can load the wheel and need a different abrasive.

Ask about the largest diameter and length the grinder can take. Ask about the tolerance and surface finish that can be held. Ask about the smallest and largest batch size.
