  • Publication number: 20220143713
    Abstract: Cutting insert for a tool for machining. The cutting insert is particularly suitable for grooving tools for grooving turning. The cutting insert has a chip breaker geometry in its cutting region, which enables both machining of full cuts and machining of partial cuts as well as machining of webs. In particular, due to the shape of a chip cavity provided in the cutting region and due to the presence of a negative chamfer, very short chips can be produced in all three machining variants, so that a high level of process reliability is ensured and long tool lives are made possible.

  • Patent number: 9468976
    Abstract: A cutting device comprising a cutting insert and a holding part with a beam part, extending in a longitudinal direction, and a clamping head, which projects beyond an upper side of the holding part with a projection, wherein the projection is connected to a first of two clamping fingers which between them form a receiving pocket for receiving the cutting insert. A clamping gap is provided underneath the projection to allow the first clamping finger to be elastically movable. The clamping gap opens out into the receiving pocket and runs from an end face of the holding part that is facing the workpiece to be worked in the longitudinal direction up to the rear end of said holding part, which rear end is arranged in the transitional region between the clamping head and the beam part. A coolant and/or lubricant guide is provided for feeding coolant and/or lubricant to a coolant and/or lubricant outlet arranged in the projection.

  • Patent number: 8434972
    Abstract: The invention relates to a broaching tool, in particular a keyway broaching tool, comprising a holder which defines a longitudinal axis and has a shank, extending in the longitudinal direction, as support for a cutting body which can be fixed in a seat of the shank by means of a clamping device. The seat has a passage which is at a distance from the free end of the shank and extends transversely to the longitudinal axis and the inside of which forms guide surfaces for bearing surfaces of the cutting body, which can be inserted into the passage in an insertion direction. An end-position limit for the inserted cutting body is formed on guide surfaces and on associated bearing surfaces. The clamping device produces a force component on the cutting body which presses the latter against the end-position limit.
