New 16C self-contained air actuated collet chuck gripping a customer’s work piece with a serrated collet. The cone shaped end of the part is inside the chuck (not seen) and stops in a female cone locater. The locater mounts to the chucks back plate making it solid (does not move). As the collet closes, it pulls the part into the hard stop giving perfect “Z” axis location. The part is turned, bored and stamp rolled.
