ABSTRACT:
A collet chuck which can be centred relative to an axis of the workpiece to be machined and suitable for machine tools in general and in particular machine tools having a number of successive positions. An inner prehensile member is capable of gripping the workpiece, and an intermediate member coaxial to the first has a conical seating which slides axially causing the prehensile member to close on the workpiece to be machined. An outer casing is rigidly attached to the prehensile member by means of a pin, and an outer ring is fitted with radial play around the periphery of outer casing. Spring members of variable tension compress the outer casing and outer ring against each other to lock them together by friction, and pusher means operable axially by a thrust member unlock the outer casing and the outer ring.
