  • Patent number: 10632539
    Abstract: A device for the fine machining of a circumferential workpiece surface arranged eccentrically relative to an axis of a workpiece. The device comprises a pressure mechanism configured to press a fine-machining tool against the circumferential workpiece surface. The device also includes a drive unit configured to drive an active section of the pressure mechanism via a first drive and a second drive. The first drive drives the active section in a movement plane that runs crosswise to the workpiece axis along a first movement trajectory. The second drive drives the active section along a second movement trajectory that is at an angle to the first movement trajectory.

  • Patent number: 10058971
    Abstract: A device for finishing a workpiece includes two pressing elements and a holding apparatus for holding the pressing elements. A finishing band is pressable against a workpiece surface to be finished. A flexurally resilient intermediate element is disposed so as to transmit a pressing force to the finishing band by means of a force-receiving surface and by means of a force-transmitting surface. The intermediate element or a plurality of them is configured to transmit pressing forces, which are offset relative to one another in a circumferential direction of the workpiece surface, to the finishing band. The force-transmitting surfaces of the intermediate element or the plurality of them are oriented in a substantially V-shaped manner relative to one another, and are substantially planar in an undeformed initial state and have a curvature in a same direction as the workpiece surface when there is a pressing force.
