  • Cutting insert and milling tool
    Patent number: 11453074
    Abstract: A cutting insert for a milling tool is provided. A median plane extends through the cutting insert. A longitudinal plane extends perpendicularly to the median plane. In a view towards a first side surface, a first axial relief face and a first axial abutment face form part of a first surface grouping on a first side of the longitudinal plane. In a view towards a second side surface, a second axial relief face and a second axial abutment face form part of a second surface grouping on the first side of the longitudinal plane. The first axial abutment face forms a substantially flat surface. The first axial abutment face extends perpendicularly to the median plane. The second axial abutment face forms a substantially flat surface. The second axial abutment face extends perpendicularly to the median plane.

  • Turning insert having peninsula and island protrusions, and turning tool
    Patent number: 11446745
    Abstract: A turning insert has two opposite main surfaces and a peripheral surface which extends therebetween and has N side surfaces, where 2<N<9. The insert has mirror symmetry about a mid-plane and 360/N degree rotational symmetry about a central axis perpendicular to the mid-plane. The insert has two main edges which each have N main cutting edges and N corner cutting edges. Each main cutting edge has two raised edge portions and a lowered edge portion. Each main surface has N main rake surfaces and N corner rake surfaces. Each main surface further has at least N convex island protrusions and N at least partially convex peninsula protrusions, any and all island protrusions associated with a given main rake surface being located between two adjacent peninsula protrusions, each pair of adjacent peninsula protrusions having at least one island protrusion located therebetween.

  • Cutting insert
    Patent number: 11400521
    Abstract: A cutting insert has a top surface, a seating surface, and an outer peripheral surface. The cutting edge includes a corner cutting edge portion, a first cutting edge portion, and a second cutting edge portion. The top surface includes a first rake face, a second rake face, a third rake face, a front side surface, an upper surface, a first side surface, and a second side surface. A ridgeline between the first side surface and the second side surface is continuous to the upper surface. When seen in a direction perpendicular to the seating surface, a width of a boundary between the front side surface and the third rake face is larger than a width of a boundary between the front side surface and the upper surface.
