In order to reduce or, if possible, completely eliminate rotational oscillations in a machining tool held in a draw-in collet chuck and thus permit the use of a prior art collet chuck (1), in a draw-in collet chuck of the main clause the annular pressure member (7) is fitted with a guide sleeve (11), especially of the one-piece type. It overlaps a cylindrical outer casing (12) of the chuck (5) or the latter's end-piece (13) with a very small radial clearance. In particular, forcing adjusting screws (18, 24) uniformly distributed around the circumference permit the exact centring of the machining tool (2). The forcing adjusting screws are fitted, for example, between the tigthtening nut (6) and the circular pressure member (7) or between the latter or its guide sleeve (11) and the chuck (5). |
