Abstract: A circulating tool for cutting of workpieces including a carrier element that bears at least one cutter blade insert in an exactly positioned manner. A device is provided for adjusting the position of the insert relative to the carrier element and a clamping device is provided using a clamping claw, with which the insert can be fixed in the adjusted position relative to the carrier element in that the clamping claw presses the insert flat against a support surface. In order to be able to use indexable inserts of any form without providing weakening openings and to obtain the greatest possible measure of free space for configuring the tool and shaving removal with a space-saving configuration of the adjusting and clamping apparatus, the insert is accommodated in a pocket of the clamping claw and the support surface is directly constructed on the carrier element.

Abstract: A clamping and adjustment apparatus for a cutting tool is described in which a plate-shaped cutter insert is prestressable and fastenable by means of a tension screw with its bottom surface against a seat surface such that it is supported with lateral wall sections in a positionally fixed manner on a cutter support. In order to allow precise adjustment of the cutter insert when little space is available, the clamping and adjustment apparatus has an adjustment wedge which can be actuated by means of a pressure screw in a direction (V) that extends essentially parallel to the seat surface. The adjustment wedge is accommodated in the cutter support in a form-fitted and displaceable manner. The cutter insert is supported on the adjustment wedge and can be adjusted by means of it. Moreover, a tool which is equipped with this clamping and adjustment apparatus is described as well as a tool cartridge which is used for it.

Abstract: The invention relates to a clamping system as a point of separation inside a tool or workpiece support system, or as an interface between a tool or workpiece support system and a machine tool for the detachable, non-positive connection of two clamping system parts. According to the present invention, it is proposed to coat at least one joining surface of a joining surface pairing between components of the clamping system parts that are to be connected in non-positive fashion with a layer of solid lubricant applied in an abrasion-resistant manner. On the one hand, this coating with solid lubricant enables significant improvement in the sliding characteristics of the joining surfaces, subjected to friction, of the components of the clamping system to be connected with one another. On the other hand, the joining surfaces, which are in addition subjected to a high surface pressure, exhibit improved corrosion characteristics.

Abstract: The invention relates to a boring tool comprising a retaining device which extends in the direction of a longitudinal axis and which comprises a shaft section and a head section. A groove which runs orthogonal in relation to the longitudinal axis and in the direction of a transversal axis is configured in said head section. The boring tool also comprises a cutting insert which is inserted in the groove, and comprises a clamping element. Said clamping element passes through a receiving boring configured in the cutting insert and through a boring configured in at least one of the groove limbs. In addition, the clamping element clamps the cutting insert against the at least one groove limb.
