ABSTRACT:
A centerless grinding machine comprises a stationary disk, a following disk, and a shoe, which cooperate to hold and rotate a workpiece. The following disk is mechanically loaded to the bias towards the stationary disk and the shoe so that the workpiece is secured between an outer circumference of the disks and the shoe. A diameter detector detects an outside diameter of the workpiece by detecting a displacement of the following disk by the workpiece. From this information, a controller controls an X-Z grinder to grind an inner surface of the workpiece. This grinding is in response to the outside detector detected by the diameter detector. As a result, the inner diameter can be machines to closer tolerances than are available in the outer diameter.
