  • Parting and grooving tool with clamping arrangements
    Patent number: 9180523
    Abstract: A parting and grooving tool includes a toolholder and a cutting insert. The toolholder has a toolholder body including a main body portion and an elastic clamping arm that define an insert-receiving pocket. The pocket has a top surface formed by the clamping arm and a bottom surface formed by the main body portion for contacting a top and a bottom surface of a cutting insert. The toolholder body includes a second arm, the second arm and the clamping arm defining a slot. A threaded hole extends through the second arm to the slot. The toolholder has a screw having threads that mate with threads in the threaded hole so that the clamping arm is movable into and out of contact with the top surface of the insert. An axis of the threaded hole is substantially perpendicular to a longitudinal axis of the insert-receiving pocket and intersects the cutting insert.

  • Cutting insert with symmetrical, radiused cutting edges
    Patent number: 9095910
    Abstract: A cutting insert includes a top surface, an edge surface and a cutting edge between the top and edge surfaces. The cutting edge is symmetrical about a centerline. The cutting edge has a first edge radius at a first point at the centerline of the cutting edge and a different, second edge radius at second points on opposite sides of and remote from the centerline of the cutting edge. The first edge radius is larger than the second edge radius. The top surface includes a land surface between the cutting edge and a remaining portion of the top surface. The land surface defines a surface that is distinct from the remaining portion of the top surface. A width of the land surface behind the cutting edge at the first point at the center of the cutting edge is different than the width of the land surface behind the second points.
