ABSTRACT:
The invention is an improved chuck for machining operations. It consists of a disc-like piece with tooth-like projections around the periphery, and a removable centering piece at the center thereof. The improved chuck is held in an ordinary three-jaw chuck in a lathe when in use. The work piece is centered on the improved chuck on the side with the tooth-like projections and held in place there by the pressure of a rotating bull-nose tailstock. The improved chuck permits machining the outside surface with the single set-up, whereas the prior art requires two set-ups, usually alternately in a three-jaw and a four-jaw chuck with various attendant difficulties.
