  • Tool clamping system
    Patent number: 10286510
    Abstract: 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.
    Type: Grant

    Date of Patent: May 14, 2019
    Assignee: BILZ WERKZEUGFABRIK GMBH & CO. KG
    Inventors: Juergen Fronius, Rudolf Bader, Ulrich Zierer
  • Tool holder with fluid supply
    Patent number: 10207331
    Abstract: A tool holder is disclosed for holding a tool shaft of a tool, the tool holder having a receiving bore for receiving the tool shaft in a predetermined axial position, having a seal at an inner end of the receiving bore, and further comprising a coolant supply from a machine-side into a bore of the tool shaft, wherein the seal has an at least partially elastically deformable sealing element.
