Disclosed is a tool system including a drive for driving a tool holder including an electromagnetic generator for generating electrical energy from inertial energy of the tool holder. The tool holder may be driven in rotation, wherein the electromagnetic generator comprises a rotor part, which is rotatably mounted on the tool holder, and a stator part on the tool holder cooperating with each other for generating a voltage by electromagnetic induction. Alternatively, an axially movable inertial mass can be used for utilization of an oscillating linear movement.

Tool clamping system

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.
