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.

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).

Abstract: The invention relates to an installation for polishing pieces of cutlery or the like, which comprises two rotatable conveyor devices, each adapted to move through a respective circular path for transporting workpiece holders for the pieces of cutlery through work stations disposed on the paths. The holders can now move on the first conveyor device from a clamping device by way of a polishing machine and a re-clamping device back to the clamping device and, on the second conveyor device from the re-clamping device by way of at least one polishing machine and an unclamping device back to the re-clamping device.
