Appl. No.:

9/324270

Inventors:

James E. Pruitt - Rockford IL

International Classification:

B24B 100

US Classification:

451 49

Abstract:

A rotating fixture includes work piece holders for carrying work pieces in a circular path for parading the work pieces one-by-one for machining engagement with a grinding wheel. The work pieces holders permit rotation or spinning of the work piece therein independently of the fixture rotation. A drive wheel engages and spins each work pieces in the holder as the work piece travels through machining engagement with the grinding wheel such that a round, outside-diameter surface is ground onto the work piece.

International Classification:

US Classification:

451 49

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.
