ABSTRACT:
A grinding apparatus comprises a base, a chuck on the base for supporting a workpiece for rotation about an axis, a first on the base to one axial side of the chuck for grinding an internal surface of the workpiece in the chuck, a second grinder on the base for grinding an external surface of the workpiece in the chuck, and fasteners for retaining the grinders releasably on the base adjacent the chuck. Thus both axial sides of the workpiece remain exposed for machining both ends of the workpiece simultaneously. The chuck is of the centerless type which engages the workpiece externally on its outer diameter between its ends, thereby leaving these ends free for grinding.
