ABSTRACT:
An attenuating adaptor is proposed in the form of a sleeve (23) which is composed of non-ferromagnetic metal for insertion radially during operation between a holding section (11) (which is provided with a central holding opening (15) for holding a tool shank with a press fit) of a tool holder (1) and an induction coil arrangement (19) (which concentrically surrounds the holding section (11) in order to widen it thermally) of a shrinkage appliance (5) which feeds alternating current to the induction coil arrangement (19). The sleeve (23) can be provided with slots which pass through its wall and whose number, axial length and circumferential width influence the attenuating characteristics of the sleeve (23). Sleeves (23) of different sizes are provided for a set of different tool holders (1), and their attenuating characteristics are chosen such that all of the tool holders (1) in this set can be shrunk using one and the same setting of the shrinkage appliance (5).
