Abstract: A rotating fixture releasably carries work pieces in a circular path for parading the work pieces, one-by-one, through machining engagement with a grinding wheel for grinding a desired feature or surface onto each work piece. The fixture is adapted such that the work pieces can be quickly snapped into position, and provision is made for automatically ejecting the finished parts from the fixture. A clamping apparatus clamps the work pieces in place in the fixture, one-by-one, just prior each piece reaching the tool, and then releases the work piece after the machining on each part is finished.
