  • Device for machining by turning
    Patent number: 8904909
    Abstract: A device (1) for machining by turning rotationally symmetrical surfaces (18, 20 or 22) of a workpiece (10), which is clamped and has a rotating drive, including a tool (12) having two cutting edges (16) and (17), each having an approximately helical shape, which are disposed one behind the other in the feed direction of the tool (12) such that after the machining by turning with the first cutting edge (16), a roughing edge, the second cutting edge (17), a finishing edge, comes into engagement.
    Type: Grant
    Filed: June 1, 2011
    Date of Patent: December 9, 2014
    Assignee: J.G. Weisser Söhne GmbH & Co. KG

  • Device for machining rotationally symmetrical surfaces of a workpiece
    Patent number: 8186251
    Abstract: To produce rotationally symmetrical surfaces of a workpiece (10), the rotationally driven workpiece (10) is subjected to rotational machining. For this purpose, a tool is used (12), whose blade (16) is advanced in a circular arc motion (f). The blade (16) takes the form of a coaxial helix in relation to the rotational axis (A1) of the tool.
