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. The guidance devices are formed on the one hand by a first guidance slide, on which the grinding device is displaceably supported in a feed direction (y-direction) which is parallel to the axis of rotation of the cup grinding wheel, and on the other hand by a second guidance slide, on which the workpiece receiver is displaceably supported in a direction (x-direction) extending in right angles to the axis of rotation of the cup grinding wheel.
