  • Cutting insert having a rake surface and a plateau surface separated by a step
    Patent number: 7306409
    Abstract: A cutting insert intended exemplarily for use in a face-milling cutter, has an all-around extending rake surface which changes into a plateau surface by an uninterrupted step. The step reaches its greatest height in the corner regions of the cutting insert. The rake surface defines a positive rake angle. The step prevents the produced chips from running onto the plateau surface. As a result of such a measure, a smear-on of material onto the plateau surface from a chip is prevented.
    Type: Grant
    Filed: April 19, 2004
    Date of Patent: December 11, 2007
    Assignee: Walter AG

  • Cutter insert and milling tool
    Patent number: 6921233
    Abstract: A cutter insert for milling tools includes a base body having a base surface, a top surface, and four side surfaces. The four side surfaces, together with each of the base surface and the top surface, define respective cutting edges. The base body is twisted about each of two perpendicular, coplanar axes of the base body. Each side surface has two opposite corner edges that are offset from one another in a direction parallel to a center axis of the base body.
