Abstract
A grinding machine (10) includes apparatus for grinding grooves in inner races (16) of constant velocity universal joints with a high production output achieved by indexing of a race without stopping rotation of a holder (14) on which the race is clamped for rotation during the grinding. An indexer (46) of the apparatus is supported for rotation with the holder (14) and provides the indexing of the race about a central axis C thereof as the holder rotation proceeds. A locater (48) also rotates with the holder (14) and accurately locates the race after indexing to provide alignment thereof with the grinding wheel (12) that performs the grinding. A jaw operator (44) controls first and second jaws (40,42) of the holder clamp and has a high clamp mode for fixing the race during the grinding and a low clamp mode for permitting the indexing and locating operations as well as an unclamp mode that permits a ground race to be unloaded and another race to be loaded onto the holder in preparation for the next cycle.
