Abstract
Apparatus as described for centering a collet chuck relative to the longitudinal axis of a dop arm for a gem faceting machine. The apparatus includes a socket mounted to the dop arm and a plug slidably received within an open longitudinal bore formed within the socket. The plug mounts a collet chuck. Two longitudinally spaced sets of screws extend radially into the socket. The individual screws of the two sets can be turned against the plug to adjust the collet chuck into a secure precise coaxial relation with the dop arm axis.
