An axially elongate dental machining portion includes a machining region machinable by a dental machining device, and a fixing region for fixing the machining portion to a holder of the machining device. In the fixing region is a fixing projection oriented transversely relative to the longitudinal axis. In a condition of the machining portion mounted in the holder, the fixing projection bears against a holding nose provided in complementary relationship on the holder. The machining region has a machinable surface which has a maximum spacing relative to the longitudinal axis, measured normal to the longitudinal axis, and the fixing projection has a maximum spacing relative to the longitudinal axis, measured normal relative to the longitudinal axis, that is greater than the maximum spacing of the surface relative to the longitudinal axis.

When a rare earth magnet block is cut or ground by a cutting or grinding tool, a jig is used for holding the magnet block in place. The jig comprises a base, a pair of metal support members disposed on opposite sides of the base and provided with grooves, and rubber rods received in the support member grooves such that the rubber rod partially protrudes from the groove and abuts on the groove bottom. The magnet block is rested on the base and clamped between the rubber rods. The volume of the groove is larger than the volume of the rubber rod.

A manual method and apparatus for removing scratches from automotive paint finishes by using a diamond abrasive compound applied to a handheld polishing disk/pad which effectively “scrubs” away the scratches. First, a first soft polishing pad is attached to a handgrip; second, an amount of a first diamond abrasive polishing paste is applied to the first soft polishing pad; next one manually polishes the metal trim or paint finish in situ without removing the metal trim from the vehicle by rubbing the metal trim or paint finish with the first soft polishing pad bearing the first diamond abrasive polishing paste. Thereafter, one removes the first soft pad from the hand grip and replaces it with a second soft polishing pad and applies an amount of a second diamond abrasive paste to the second soft polishing pad, the second diamond abrasive paste having a finer grit than the first diamond abrasive paste. One then manually polishes the metal trim or paint finish in situ by rubbing the metal trim or paint finish with the second soft polishing pad bearing the second diamond abrasive polishing paste. A third, yet finer, diamond abrasive compound can be used in conjunction with a third soft polishing pad. The apparatus comprises a soft hand grip, a plurality of soft polishing pads for attachment to the hand grip and for polishing with abrasive paste, and a plurality of containers of diamond abrasive paste of varying grits to be applied to the soft polishing pads.

The super finishing stone has such a shape that a width of an abrasive surface in a direction perpendicular to a radial direction becomes gradually narrower from outside to inside in the radial direction, when the raceway surface and the abrasive surface in contact with the raceway surface are seen at a plurality of sections perpendicular to the radial direction of the object to be worked, so that the abrasive surface and the raceway surface in contact with the raceway surface may intersect with each other at a constant angle at opposite side edges of the abrasive surface.

A method and an apparatus for polishing a curved edge of a molded part. A surface of the curved edge is abraded by contacting a polishing surface of a first polishing wheel to the curved edge repeatedly in a first direction concurrent with a rotational spinning direction of the first polishing wheel. The abraded surface of the curved edge is polished by contacting a polishing surface of a second polishing wheel to the curved edge in the first direction and in a second direction opposite to the first direction. The polishing surfaces of the first and second polishing wheels are shaped to conform to a portion of the surface of the curved edge of the molded part. The polishing wheel is maintained at a constant rotational speed by a controller when contacting the curved edge. The polished surface of the curved edge is visually smoothly uniform in reflective appearance.

The present invention relates to a method for surface treatment of a wind turbine rotor blade (1) comprising a leading edge and a trailing edge separating substantially opposing first and second surfaces of said rotor blade. The method comprises the steps of providing a wind turbine rotor blade, supporting said rotor blade at least at a root end and at a distal position along a longitudinal axis of the rotor blade and providing moveably arranged first and second surface treatment devices (24, 25) adapted to provide surfac treatment of the first and second surfaces of the rotor blade, respectively, wherein the first and second surface treatment devices are moved in opposite directions and towards the leading and trailing edges, respectively, during surface treatment of the first and second surfaces of the rotor blade.

A method for generating openings in a metal foil includes at least the following steps: a) providing a planar metal foil, b) generating at least one bend in the metal foil, and c) generating at least one opening in the region of the at least one bend through the use of a cutting production process. Grinding tools are preferably used. A method for producing a honeycomb body, an exhaust gas treatment unit for mobile internal combustion engines having a honeycomb body and being produced by the method, as well as a motor vehicle, are also described.
摘要:
An attachment for an oscillatory sanding or abrading device has a pair of flexible support members for supporting the sanding or abrading material. The initial radius of curvature of the flexible support member may be adjusted by a pneumatic adjustment mechanism. An opposing pair of generally cylindrical bladders are disposed proximate end portions of the flexible support member, the bladders being releasably attached between the underside of the abrading device and the support member. Adjustment of the initial radius of curvature of the flexible support is accomplished by selectively inflating one or both of the bladders. The radius of curvature of the flexible support member during the sanding process is then a function of the applied pressure or inflation of the bladders. The device allows for virtually infinitely varying adjustments of the curvature of the flexible sheet and the attached abrading sheet.
