  • Cutting insert for profiling turning and cartridge for receiving a cutting insert
    Patent number: 10507531
    Abstract: A cutting insert for profile turning, in particular for wheel profile turning, includes an upper surface, a lower surface, and side surfaces. At the transition from the upper surface to the side surfaces two cutting edges are formed for machining a workpiece and two further edges each having two ends. The two cutting edges are designed part-circular in shape and each extend from one end of one of the two edges to the opposite end of the other of the two edges. Also described is a cartridge for holding a cutting insert, the cartridge being mountable on a machine tool. The cartridge has a main seating surface having a plane angle (?) of greater than 90° to the axis of rotation (D) of the workpiece.
