Abstract: A damping apparatus is provided for damping vibrations of a tool-holding apparatus during machining of a workpiece. The damping apparatus comprises a damping body having two ends on which a respective damping device is arranged, which comprises a bearing pin rigidly connected to the damping body and a bearing bush that surrounds the bearing pin in the circumferential direction. An annular space filled with a damping fluid is arranged between the bearing pin and the bearing bush, which annular space is sealed in the axial direction by two elastically deformable sealing rings. The two sealing rings each comprise first and second abutment regions as well as a resilient intermediate region arranged therebetween. The first abutment region is bonded to the bearing pin and the second abutment region is bonded to the bearing bush. The intermediate region is elastically deformable relative to the bearing pin and the bearing bush.

Abstract: The invention relates to a cutting tool apparatus comprising a tool head rotatingly drivable about an axis of rotation, which tool head has a tool slide adjustable along an adjustment axis and an electrical measuring device for detecting an adjustment path of the tool slide, and comprising an external display device which is mechanically and electrically releasably connectable to the tool head and has a display unit for displaying the adjustment path of the tool slide. In order to further develop the cutting tool apparatus such that its handling is simplified, it is proposed according to the invention that the display device is mechanically securable on the stationary tool head in order to set the tool slide and is automatically releasable from the tool head if a predeterminable rotational acceleration of the tool head is exceeded.

Abstract: A precision turning tool has a rotatingly drivable tool body. A tool slide and corresponding compensating slide are displaceably mounted in the tool body. The tool slide is displaceable along an axis of adjustment aligned at right angles to an axis of rotation of the tool body. The compensating slide is automatically displaceable along an axis of compensation aligned parallel to the axis of adjustment contrary to the movement of the tool slide to compensate for any imbalance. At an end projecting out of the tool body in the direction of adjustment the tool slide has a mounting surface, on which a cutting plate carrier can be mounted. An electronic distance measuring system is provided with a display unit and an energy supply device, wherein the distance of adjustment of the tool slide can be detected by means of the distance measuring system and displayed.
