Centerless grinding wheel

Centerless grinding differs from other cylindrical processes because the workpiece is not mechanically constrained. It’s a precision grinding technique used to achieve roundness, surface finish and dimensional tolerances that are among the best available.

Centerless grinding is an outer diameter finishing process that is revered for maintaining a high tolerance for roundness on metal parts and working very quickly, making it ideal for high-volume applications. And it’s the relative simplicity of centerless grinding that separates it from other cylindrical grinding technologies.

At first glance the process appears almost primitive. The part to be ground is simply placed on a workpiece rest blade that is situated between two rotating cylinders: a regulating wheel (made of a dense rubber compound that controls the rotational speed and feed rate of the workpiece) and the larger abrasive grinding wheel.
