Centerless grinding is a special type of grinding that is used to produce workpieces that, because of their shape, cannot be machined between the centers and supported by the spindle... and tailstock. In this particular grinding operation, the workpiece is placed between two grinding wheels that rotate in the same direction. As with lapping operations, the two grinding wheels have different diameters. The smaller grinding wheel moves the workpiece into contact with the larger grinding wheel itself. The larger grinding wheel turns at very high speeds while the drive wheel has a very slow rotary motion. There are two types of grinding that can be carried out with centerless grinding machines and they are throughfeed grinding and plunge grinding. Centreless grinding machines are very complex machines with a high technological content and are used mainly in the automotive sector and in the bearing industry.
