The invention has a turnback roll which can transfer and guide a polishing tap in a tangential direction of a pressure contacting roll, a vertical oscillation mechanism which linearly oscillates the pressure contacting roll in a tangential direction of a ball groove while being orthogonal to a rotating axis line, and a horizontal oscillation mechanism which linearly oscillates the pressure contacting roll in a direction of a rotating axis line toward both inner side surfaces of the ball groove. The ball groove can be securely polished by the polishing tape on the basis of the continuous or intermittent transfer of the polishing tape and the linear oscillating motion of the ball groove. It is possible to improve a polishing precision, it is possible to improve a surface roughness of the ball groove and it is possible to improve a polishing workability of the ball groove.

The present invention provides an apparatus and method for processing a component surface by abrading the component surface using an abrasive surface. The apparatus comprises an abrasive surface which is rotatable about an axis extending parallel to said component surface. A support is provided for moving the abrasive surface or the component surface along a computer-generated toolpath and for applying a force between the abrasive surface and the component surface. The support increases the force between the abrasive surface and the component surface from a minimum force to a maximum force as the distance along the toolpath increases to maintain constant material removal from the component surface.

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).

A device for recontouring a gas turbine blade includes: a holding device having at least one cutting tool; and a guide configured to guide the cutting tool along a leading edge of the gas turbine blade. The cutting tool is configured to remove material from the gas turbine blade using a rotational movement about an axis of rotation. The axis of rotation forms an angle together with a chord of the gas turbine blade in a profile section plane, which extends perpendicularly to a radial extent of the gas turbine blade, and the angle is less than 45?.

Wheel cleaning systems and methods are described for removing corrosion from a wheel rim. An enclosure comprises a plurality of walls that define a work area, and houses a turntable that can hold a wheel rim. The turntable is driven by a motor to rotate the wheel about an axis. The enclosure may have a transparent shield or window to allow a user to view the wheel during the cleaning process and be protected from sparks and other debris. The enclosure may be fully enclosed with gloved openings, or contain one or more open sections to allow the user to maneuver a tool (e.g., a grinder) in multiple positions within the enclosure, and clean the wheel rim. The system further comprises an exhaust unit that draws out small particles and airborne debris from within the enclosure, and produced during a cleaning process.
