  • Patent number: 11097364
    Abstract: The invention relates to a method and a machine tool for hard finishing toothed gearing, particularly internally toothed portions (3), in which method a toothed hard finishing tool (W) which rotates about its axis of rotation is brought into rolling machining engagement with the machined toothed gearing in one pass or in a plurality of passes of differing radial infeed depth under an advance motion with a direction component parallel to the axis of rotation (C) of the machined toothed gearing and under a non-null axis crossing angle, and material is removed from the machined toothed gearing with a tooth flank region (4a) of the machine tool gearing with tooth thickness increasing in the tooth trace direction from the end face (5) facing the machined toothed gearing.
    Type: Grant

  • Patent number: 9796031
    Abstract: The invention concerns a method for the machining of toothed workpieces, in particular for the plastic reshaping of the tooth edges at the ends of the teeth through a meshing tooth engagement with a tool that is rotatable with free-running mobility about its axis of rotation, in particular a chamfering tool, wherein between the machining of one workpiece and the next, the tool is subjected to a traverse movement, whereby the tool is caused to perform a rotary movement so that, if a tool region (6a, 6b) that is designed for the initial engagement with the work pieces is not suitably positioned, it is brought into a position that is suitable for the machining of the next work piece, wherein the rotary movement is effected by coupling the rotary movement at least in sections to the traverse movement.

  • Patent number: 8821216
    Abstract: A method and a device for removing secondary burrs raised on the tooth flanks of a work piece wheel by a chamfering of the end tooth edges of said work piece wheel provides a tool wheel that rotationally meshes with the work piece wheel. Said tool wheel has cutting edges on its tooth flanks (5, 6) and their cutting motion, caused by the meshing, removes the secondary burrs by cutting.

  • Patent number: 8684637
    Abstract: An arrangement for the non-rotational connection between a toothed tool wheel for the machining of end peripheral areas of tooth flanks, having an axis of rotation, and a tool holding fixture that can be rotationally driven around an axis of rotation. Said arrangement has an elastic means with a restoring force against which the direction of the axis of rotation of the tool wheel can be displaced relative to the direction of the axis of rotation of the tool holding fixture.

  • Patent number: 8182313
    Abstract: A carriage arrangement for a machine tool, which can be adjusted similar to a compound slide, has an increased rigidity against a machining force being taken up by said arrangement in that according to the invention a first carriage (1) can be adjusted relative to a machine base (4) along a first trajectory that is tilted toward the direction of force, and a second carriage loaded with the machining force can be adjusted at the first carriage along a second trajectory that is orthogonal to the direction of force (FIG. 1).
