ABSTRACT:
A device (10) for thermally clamping and releasing tools (11) in shrink-fit chucks (12), having a socket (15) for a shrink-fit chuck (12), a heating unit (16) that can be moved toward and away from the mounted shrink-fit chuck (12), and a cooling unit (20) for cooling the heated shrink-fit chuck (12). The cooling unit (20) has at least one coolant distributor (21, 22) that is capable of moving in relation to the socket (15) with the mountable shrink-fit chuck (12), conveys a preferably fluid coolant, e.g. cooling water, and has outlets (23) for the coolant, which are oriented toward the socket (15) with the mountable shrink-fit chuck (12) and out of which the coolant travels under pressure to act on the outside of the socket (15) with the mountable shrink-fit chuck (12) for cooling purposes (FIG. 1).
