  • Patent number: 8066454
    Abstract: The present invention relates to an indexable cutting insert for an end mill for machining of contours in a workpiece and to a milling tool. The cutting insert is asymmetrical in respect of a line through a hole in the cutting insert. The cutting insert includes two cutting edge portions. Each cutting edge portion comprises of a substantially straight cutting edge and a curved cutting edge along respective intersecting lines between a clearance surface and a chip surface. The curved cutting edges have different lengths. The cutting insert includes recesses in a bottom side of the cutting insert. The recesses are arranged on both sides of and at different distances from the hole of the cutting insert.

  • Patent number: 7252461
    Abstract: A milling cutter for chip removing machining includes a milling cutter body with a number of insert pockets in connection with an end of the milling cutter body. An opposite end of the milling cutter body is adapted to cooperate with a tool attachment. An indexable cutting insert is secured in the cutting insert seats, each indexable cutting insert having two substantially identical main surfaces. Two side surfaces and two end surfaces extend between the main surfaces, each main surface including two cutting insert corners, each cutting insert corner including major cutting edge and a minor cutting edge. Parts of each main surface include rake faces. Parts of each side surface and each end surface include clearance surfaces. The cutting insert has a height between the end surfaces and each main surface includes an associated support surface.
