  • Patent number: 11980957
    Abstract: The present invention shows an apparatus for a chamfer machining of a toothed workpiece comprising a workpiece spindle having a workpiece holder rotatably supported about an axis of rotation for holding the workpiece, a tool spindle having a tool holder rotatably supported about an axis of rotation for holding a finger mill, wherein the tool spindle is travelable relative to the workpiece holder via at least one linear axis of the apparatus, and a control having a machining function that rotates the workpiece held in the workpiece holder by controlling the workpiece spindle for the chamfer machining of a toothed workpiece while a finger mill held in the tool holder engages at the edge to be machined. It is characterized in that the machining function varies the rotational speed of the workpiece during the chamfer machining.

  • Patent number: 11268800
    Abstract: The present application discloses a method for calibrating a measuring probe in a gear cutting machine by using a workpiece received in a workpiece holder of the gear cutting machine, wherein the measuring probe includes a measuring probe tip which is movably arranged on a measuring probe base, wherein the deflection of the measuring probe tip relative the measuring probe base can be determined via at least one sensor of the measuring probe, and wherein the measuring probe is traversable relative to the workpiece holder via at least two axes of movement of the gear cutting machine. The method comprises rotating the workpiece via an axis of rotation of the workpiece holder and traversing the measuring probe via the at least two axes of movement of the gear cutting machine such that in the case of a perfect calibration the touch point of the measuring probe tip on the tooth flank would remain unchanged.
