The tool holder, which serves principally for receiving a thread cutting tool, has a length compensation under tension and compression. This purpose is served by two compression springs which comprise massive elements of foamed, open and closed cell polyurethane elastomer. This material has good spring and damping properties. The compression springs operate without fatigue. The tool holder also has a coupling which permits radial movements of the thread cutting tool transverse to the axis of rotation in order to compensate for alignment errors. |
