Abstract
A chuck support base for very accurate machining of parts includes a pair of interengaging members through which rotary motion is delivered to a tool holding chuck. The member on which the chuck is mounted has a ring with an internal frusto-conical exterior surface of a drive member mounted on the chuck support base of a machine tool. Both the ring and the driver member are secured to their supporting members by a bonding agent which initially is liquid and hardens while the structure to which it is attached is rigidly supported in a jig so that any variation from total concentricity with the axis of rotation of the tool is eliminated by compensating the positioning of the two rings before the bonding agent sets.
