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

Device with a cooling unit for thermally clamping and releasing tools in shrink-fit chucks

A tool holder for holding a tool has at least one sensor for measuring an operating parameter of the tool holder or the tool during the operation thereof and generating measured value signals which are fed to a signal processing unit for evaluation. The sensor is a surface acoustic wave sensor operating according to acoustic wave principles and its measured value signals are readable in a contactless manner by means of radio waves. The surface acoustic wave sensor requires no current supply circuit but instead draws transmission energy required for transmission of the measured value signals to the signal processing unit from a high frequency interrogation signal, that is transmitted by radio waves from the signal processing unit and is received by the surface acoustic wave sensor.
