Abstract: A pressure shoe (1) includes a press surface (2) for directly pressing finishing tape onto a radial circumferential surface (3) of a rotating workpiece section (4) during a finishing process. A plurality of expansion elements (5) is formed in the pressure shoe (1). Each of expansion elements (5) are expandable individually and independently of one another radially while deforming the press surface (2) in a direction of the circumferential surface (3) of the workpiece section (4), so that during the finishing process, the shape of the circumferential surface (3) of the workpiece section can be influenced in a targeted manner via different expansion of the expansion elements (5) distributed over the press surface (2).

Abstract: A pressing device (1) for pressing finishing tape against circumferential surfaces (2) of substantially cylindrical work piece sections (3) in a finishing process includes at least one elastically bendable pressing element (5) that is substantially inelastic in the longitudinal direction. A support element (6) has two bearings (7), which are arranged at a distance from each other. The pressing element (5) is fastened to the two bearings, and the two bearings are arranged in such a manner that finishing tape is pressed against a circumferential surface (2) by the pressing element (5) across a contact angle (4) using a pressing force. The pressing device (1) is adjustable in order to process work piece sections (3) of different diameters. The pressing element may be a toothed belt (5) having tooth-like ribs (8), and the toothed belt (5) is interlockingly mounted in the support element (6) using the tooth-like ribs (8).

Abstract: A device for producing a curved surface (2) of a work piece (1) includes a tool (3) and a tool holder for receiving the tool (3), the tool holder being drivable for rotation about a tool axis (4). At least one work piece holder accommodates a work piece (1). The work piece holder is drivable for rotation about a work piece axis (5). The tool axis (4) and the work piece axis (5) are positionable at an angle relative to one another. The tool axis (4) and the work piece axis (5) are positionable at an angle relative to one another. A work piece holder support (6) receives a plurality of work piece holders, the work piece holders being rotatably drivable relative to the work piece holder support (6).

Abstract: In a method for end processing a surface of a shaft-like workpiece, the following steps are performed in the following series, and the workpiece rotates about an axis of rotation: a) finishing the surface with a first finishing tool, b) machining the surface with a scoring tool, whereby the scoring tool produces at least one groove running in a circumferential direction, whereby the at least one groove produces 3 to 12 profiled gorges on a reference segment which reference segment has a length that is predetermined by a measuring method for roughness determination and which is extending on the surface parallel to the axis of rotation, each of said profiled gorges having a depth and width, whereby the ratio of the depth and width of each profiled gorge is greater than 2 and a distance between adjacent profiled gorges is substantially the same, c) machining the surface with the first finishing tool or a second finishing tool.

Abstract: A radially inwardly open raceway formed in a nut centered on a nut axis is machined by of oscillating the nut about the nut axis while pressing a tool secured in a holder radially outwardly into the raceway of the nut. The holder is moved parallel to the nut axis and oscillated about a tool axis perpendicular to the nut axis synchronously with the oscillation of the nut about the nut axis. Springs brace the tool against the holder parallel to the nut axis such that the tool can move limitedly in the holder against spring bias parallel to the tool axis.

Abstract: A method for the finishing treatment of work pieces, uses a processing device including a tool spindle for a processing tool and a numerically controlled (NC) feeding device. The force of the contact pressure applied to the work piece on the side of the work piece is measured and the measured force values are supplied to the numerical control (NC), which determines and fixes the feed rate at which the processing tool is advanced against the work piece. The finishing treatment is carried out in a force-controlled operating mode, in which the feed rate is controlled depending on the force of the contact pressure acting on the processing tool. A processing device is employed whose tool spindle is movably supported in the direction of the feeding movement on leaf springs on the feeding device. The processing device includes a force-measuring device effective between the tool spindle and the feeding device and operating substantially free of deformation.
