  • Publication number: 20230356311
    Abstract: A double-ended parting cutting insert. The cutting insert includes two cutting portions at opposite ends thereof which are oriented at 90° to each other. The cutting insert includes a pair of rake and support engagement grooves, the rake and support engagement grooves of each one of the pair converging in a direction away from a respective cutting portion. An insert holder includes a clamping portion having a resilient upper clamping jaw having an upper engagement ridge and a lower base jaw having a lower engagement ridge. A gap therebetween forms an insert receiving slot that has a slot opening. The upper and lower engagement ridges converge in a direction away from the slot opening. When the cutting insert is releasably attached to the insert holder, to constitute a fastened position of a cutting tool, the cutting insert is located in the insert receiving slot and resiliently clamped therein.

  • Patent number: 10710174
    Abstract: A slitting cutter having a disk-shaped cutter body with a plurality of circumferentially spaced insert receiving portions and a plurality of cutting inserts retained therein. Each insert receiving portion has first and second clamping jaws spaced apart by an insert receiving slot, the first clamping jaw resiliently displaceable and having a resilient axis of rotation. The number of cutting inserts resiliently clamped in the slitting cutter is an inner cutting diameter defined by the plurality of resilient axes of rotation multiplied by a spacing factor of between 0.15 and 0.30. A tool key having first and second key prongs is used in combination with the slitting cutter. The second key prong has a thrust surface with a concave profile. In a partially assembled position of the slitting cutter the thrust surface contacts at least one of two spaced apart first and second corner surfaces of the respective cutting insert.

  • Patent number: 10363722
    Abstract: A blade-shaped cutting insert has opposing first and second insert side surfaces with a peripheral surface extending therebetween, and a first cutting portion having a first primary cutting edge extending between the first and second insert side surfaces, defining a maximum insert width of the cutting insert. The peripheral surface includes an upper surface and first and second diverging flank surfaces bisected by a first plane transverse to the upper surface. The cutting insert has a maximum insert length measured perpendicular to the first plane which is more than sixteen times greater than the maximum insert width, and a maximum insert height measured parallel to the first plane which is more than ten times greater than the maximum insert width. The cutting insert is removably secured in an insert receiving pocket of a tool holder, which is defined by an upper clamping jaw and a lower clamping jaw.

  • Patent number: 10160040
    Abstract: A cutting tool having a tool holder, cutting insert and clamping member. The tool holder includes an elongated supporting surface extending in a rearward-to-forward direction. The cutting insert has a central portion and three cutting portions, the central portion having two opposing side surfaces and three spaced apart locating surfaces defining a first imaginary triangle. The cutting insert is indexable about a central axis intersecting the two side surfaces. Each locating surface intersects two of three bisector planes containing the central axis and bisecting respective corners of the first imaginary triangle, and the cutting edge of each cutting portion is located entirely outside of the first imaginary triangle. In each index position the clamping member is located entirely rearward of a first vertical plane containing the central axis and perpendicular to the rearward-to-forward direction, and one of the locating surfaces is in clamping contact with the supporting surface.
