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.

Abstract: The invention relates to a tool holder for use in machine tools, comprising a main body, which can rotate about an axis of rotation, and cutter holders which each hold a cutting plate and can be radially adjusted by means of an axially displaceable control rod and coupling means. In order to further develop said tool holder so that it is possible, within a very short time, to produce a turned groove which satisfies stringent demands regarding surface quality and geometric roundness, it is proposed, according to the invention, that the tool holder has at least two cutter holders which can be radially adjusted between a retracted position and an extended position and whose cutters can be simultaneously brought into engagement with the workpiece in order to produce a turned groove.

Abstract: In order to further develop a device for the machining of the ends of tubes for producing a welding joint comprising a housing which can be secured on the end of the tube to be machined and on which a rotatingly drivable shaft is mounted, and comprising a rotary unit non-rotatably arranged on the shaft with a radially adjustable tool slide, on which a cutting plate is held, in such a manner that the welding joint can be produced in a shorter machining time and with a high-standard surface quality it is provided in accordance with the invention for the tool slide to be adjustable continuously in a radial direction, wherein the radial adjustment of the tool slide is coupled to the rotary movement of the shaft via gear means, and for the cutting plate to be held on the tool slide so as to be adjustable axially, parallel to the longitudinal axis of the shaft.

Abstract: A boring tool comprises a rotating tool body, a tool slide transversely displaceable therein, a cutting plate arranged on the tool slide and a micrometer screw for adjusting the tool slide, this micrometer screw being mounted transversely to the axis of rotation of the boring tool so as to be rotatable and axially non-displaceable. The micrometer screw is mounted in the tool body at a distance from the tool slide and drives a drive slide displaceable transversely to the axis of rotation of the tool body. A transfer lever is pivotally mounted in the space between drive and tool slides and engages with one arm on the drive slide and with the other arm on the tool slide such that when the drive slide is displaced the tool slide is entrained in the opposite direction to the drive slide.
