ABSTRACT:
The upper portion of a frame of a lapping device is provided with a device for supplying a workpiece, a grindstone, and a delivering device, and a movable arm is horizontally and movably supported by a support column of the frame in such a manner that the arm moves above the supplying device, grindstone, and the delivering device. The movable arm is provided with an device for autorotating the workpiece, the autorotating device being able to move upwardly or downwardly through the pressurizing device, and the movable arm further being provided with a device for holding the workpiece beneath the autorotating device. The workpiece is transported by the holding device to a position above the grindstone, and is brought into abutment with the grindstone by a holding member which is disposed at the lower end of the autorotating device, whereby it is ground with being rotated.
