A compliant collet chuck for firmly clamping a workpiece has a base member attachable to the faceplate or spindle of a lathe. The base member has a central bore having a tapered portion and which is surrounding by a channel. A bayonet cylinder occupies the channel and has circumferential bayonet slots which receive eccentric locking pins therein. An adjustable collet chuck has a tapered portion at one end that bears against the tapered bore in the base member and a second tapered portion at the other end. An axial free play nut having a tapered bore, which is adapted to bear against the second taper, is threaded into the bayonet cylinder, and rotation thereof produces through the tapers, a radial force to compress the central bore of the chuck to grip the workpiece. Rotation of the actuating pins flexes the bayonet beam to lock the workpiece in place within the chuck.
