ABSTRACT:
A collet arrangement comprises a collet having a taper at its work-piece receiving segmented head. The collet is axially fixed relative to a chuck body by means of a screwed bush. The latter is locked axially to the chuck body by being trapped under the heads of bolts, and is locked against rotation by means of a pin. The chuck body is secured to the machine spindle. A tapered sleeve is slidable between the chuck body and the collet and is secured to a draw tube by bolts, an actuating plate and an adaptor ring. These bolts freely slide through the chuck body and can thus move the tapered sleeve in an axial direction relative to the collet so that their respective tapers cause the collet segments to grip and release the work piece. Unlike the normal draw back type of collet arrangement, the collet itself is therefore axially fixed.
