摘要

The collet chuck (1) comprises two brackets (5) made of a non-hardened metal, a non-hardened alloy or a plastic, of which one bracket is arranged and dimensioned, such that it projects into an inner cross-section of the collet chuck. The inner cross-section is designed to receive a workpiece. The bracket partially closes the inner cross-section in an open position of collet chuck and the inner cross-section is partially accessible after processing that decreases the dimensions of the bracket.
