ABSTRACT:
A shrinking arrangement for a tool holder (12) which retains a rotary tool (10) with a press fit in a central accommodating opening (20) comprises an accommodating unit (24) for accommodating the tool holder and a temperature-controlling arrangement (46, 64) at least for the thermal expansion, in particular also for subsequent cooling, of the tool holder in the region of the accommodating opening. According to the invention, the accommodating unit is arranged on a carriage (32) which is guided such that it can be displaced in the longitudinal direction of the rails of a rail system (30), which runs parallel to the axis (16) of the tool holder accommodated in the accommodating unit and is fastened on a supporting base (28), and it being possible for said carriage to be moved along its displacement path into at least one region of action of the temperature-controlling arrangement. It is preferably the case, furthermore, that a positioning/mounting unit (36) which retains the tool (10) in a radial position relative to the tool holder (12) is arranged on a further carriage (34), which is guided such that it can be displaced in the longitudinal direction of the rails of the rail system (30) independently of the first-mentioned carriage (32).
