Centerless grinding with a Cincinnati 220 8 Centerless Grinder is a precision grinding process used to machine cylindrical workpieces with high accuracy and surface finish. Unlike conventional grinding methods, centerless grinding does not require the use of a centering device or chuck to hold the workpiece in place. Instead, the workpiece is supported by a regulating wheel, while a grinding wheel removes material from the workpiece.

In centerless grinding, the workpiece is fed through the grinding machine like a Cincinnati 220 8 Centerless Grinder between the grinding wheel and the regulating wheel. The regulating wheel controls the rotational speed and feed rate of the workpiece, while the grinding wheel removes material by making contact with the workpiece. The geometry of the grinding wheel is carefully set to achieve the desired diameter, roundness, and surface finish of the workpiece.

Centerless grinding offers several advantages. It enables high productivity, as multiple workpieces can be ground simultaneously using a continuous feed mechanism in a Cincinnati 220 8 Centerless Grinder. The process is also suitable for long, slender workpieces that may be difficult to support using traditional grinding methods.
