<p>Shrinking device for a tool holder (12) holding a rotating tool (10) in a press fit in a central receiving opening comprises a receiving unit (24) for receiving the tool holder, and a heating device (46, 64) at least for thermal expansion, especially also for subsequent cooling of the tool holder in the region of the receiving opening. The receiving unit is arranged on a carriage (32), which is movably guided on a rail system (30) fixed in a support base (28) running parallel to the axis (16) of the tool holder held in the receiving opening and is moved along its movement path into the active region of the heating device. An independent claim is also included for an alternative shrinking device. Preferred Features: The carriage is moved into different axial positions along the rail system for heating and for cooling the tool holder.</p> |
