  • Patent number: 5265380
    Abstract: The invention relates to a cup grinding machine for grinding oblong workpieces with a grinding device with a cup grinding wheel rotationally drivable about an axis of rotation and a workpiece receiver, which comprises a clamping device for retaining the workpiece during the grinding process with a longitudinal direction of the workpiece being angled approximately at 90.degree. to the axis of rotation of the cup grinding wheel and which is displaceable in relation to the cup grinding wheel in a plane (x-y-plane), which is parallel to the axis of rotation of the cup grinding wheel and of the longitudinal direction of the workpiece by means of guidance devices.

  • Patent number: 4869025
    Abstract: A grinding machine, in particular for grinding scissors parts or knife blades, has a grinding wheel that can be driven to rotate, a workpiece socket, and a guide device for guiding the workpiece socket during the grinding operation. In order to enable fully automatic grinding of all the surfaces on a workpiece that are to be ground, in particular on scissors parts, knife blades or the like, using only a single grinding machine, the workpiece socket is disposed on a compound slide that is displaceable in an X-Y plane and is embodied as rotatable about a pivot axis (Z axis). The workpiece socket has at least one clamping device, which is disposed on the workpiece socket in such a manner that the primary longitudinal direction of a workpiece fastened in place extends substantially parallel to the pivot axis (Z axis).
