And Burnishing Simultaneously Patents (Class 409/4)
  • Publication number: 20140050546
    Abstract: A method for cutting teeth in workpieces, wherein, in a roughing operation, a substantially uncut blank receives rough teeth using a cutting tool having cutting teeth. Operation teeth are produced, the tooth width of which is defined by the spacing between the flanks of the teeth and is greater than the target dimension. In a subsequent deburring operation, a chamfer is incorporated into the end face edge of the tooth flanks, accompanied by the removal of an end face burr. Lastly, in a smoothing operation, the tooth width of the teeth is brought to the target dimension by machining the tooth flanks.

  • Patent number: 8567039
    Abstract: The present invention relates to a machine tool and a corresponding process for machining a workpiece by means of one or more tools controlled by means of control data, the machine tool comprising at least 5 simultaneously controllable axes. A control device being suited to control the tool supported in a support means by means of the control data along a tool path to remove material from the workpiece clamped in a clamping means. The machine tool being suited to machine a first workpiece to provide the first workpiece with a first gearing, the first workpiece being a counter piece to a second workpiece having a second gearing.

  • Patent number: 8069566
    Abstract: An operating method improves the running behavior of gearwheels negatively noticed upon gearwheel testing and is performed by a burnishing device. The gearwheels that were rejected from the production process may be optimized rapidly and in a targeted way so that they may be returned back into the production process. The tooth flanks of a gearwheel to be machined are, in a first method step, mechanically freed of particles adhering to the surfaces of the tooth flanks or slight protrusions protruding therefrom using a first gearwheel machining tool having a machining wheel coated with an abrasive agent. Subsequently, in a second method step in a second gearwheel machining tool known as a burnishing machine, the gearwheel is chucked between gearwheel-shaped rolling tools, the so-called burnishing wheels, and rolled without material abrasion.
