  • Patent number: 9925597
    Abstract: A chuck for clamping workpieces or tools in a clamping space with a clamping force (F). The chuck includes at least two chuck jaws movable in translation along one clamping plane (E) in the direction of one center Z of the clamping space and a gear train located at least largely within the chuck for transfer of a driving torque of a drive motor, which can be coupled to the gear train by coupling means of the gear train, to the chuck jaws for movement of the chuck jaws. The coupling means able to be coupled to a corresponding coupling connection of the drive motor. The movement from the maximum size of the clamping space to the minimum size of the clamping space is executed via the gear train from the drive motor.

  • Patent number: 9449863
    Abstract: A device for aligning and prefixing a flat substrate on a carrier substrate for the further processing of the substrate. The device includes aligning means for aligning a substrate's outside contour relative to a carrier substrate's outside contour by engaging the substrate's outside contour. The alignment of the substrate is carried out along a substrate plane E that is parallel to a contact surface of the substrate. Attaching means is provided for at least partial prefixing of the aligned substrate on the carrier substrate.
