Centerless Grinding

Centerless grinding

Centerless grinding is an OD grinding process. It differs from other cylindrical processes in that the work-piece is not mechanically constrained. Centerless grinding is used to achieve roundness, surface finish and dimensional tolerances that are among the best available in metalworking.

Centerless Grinding Produces Finishes That Are Among the Best

Centerless grinding can be the least understood method of grinding. The method differs from other grinding processes, like OD grinding, in that the workpiece is not restrained by any mechanical devices. It is simply a relationship between the grinding wheel, work blade, and the regulating wheel.
