  • Patent number: 9956662
    Abstract: Method and apparatus for sharpening a cutting tool. In some embodiments, an abrasive endless belt is rotated in tension along a neutral plane between spaced apart first and second rollers. A guide assembly has spaced apart first and second guide surfaces which collectively converge to an intervening base surface to form a guide channel. Upon insertion of a blade of a cutting tool into the guide channel, a selected side of the blade contactingly slides against at least a selected one of the first or second guide surfaces and a first portion of a cutting edge of the blade contactingly engages the base surface to serve as a plunge depth limit stop for the blade. The endless belt is contactingly deflected by a second portion of the cutting edge away from the neutral plane to sharpen the second portion while the first portion remains in contact with the base surface.

  • Patent number: 9266211
    Abstract: A smoothing method and a smoothing apparatus has been achieved, which make it possible to automate smoothing of welded members that was formerly carried out manually. The method according to the present invention uses a belt grinding apparatus, which includes an endless grinding belt and a press pad that presses the grinding belt against a welded area, and uses this belt grinding apparatus in two different modes after obtaining information on heights of surfaces of two welded members along a weld bead of the two welded members. The first mode corresponds to a bead removing step in which the grinding belt is pressed against a welded area by the press pad to reduce the height of the weld bead. At this time, the grinding belt is made to run at a fixed position, while the press pad is made to move toward and away from the welded area (the surface thereof).

  • Publication number: 20120244787
    Abstract: The polishing apparatus has a polishing unit capable of polishing a peripheral portion of the substrate to form a right-angled cross section. The polishing apparatus includes: a substrate holder that holds and rotates the substrate; guide rollers that support a polishing tape; and a polishing head having a pressing member that presses an edge of the polishing tape against the peripheral portion of the substrate from above. The guide rollers are arranged such that the polishing tape extends parallel to a tangential direction of the substrate and a polishing surface of the polishing tape is parallel to a surface of the substrate. The substrate holder includes: a holding stage that holds the substrate; and a supporting stage that supports a lower surface of the peripheral portion of the substrate in its entirety. The supporting stage rotates in unison with the holding stage.

  • Patent number: 8192249
    Abstract: A polishing system and associated methods are described for polishing a magnetic disk used in a disk drive system. The polishing system includes a polishing film that is used to polish the magnetic disk. The polishing system also includes an actuator operable to move the polishing film across a surface of the magnetic disk to polish the magnetic disk. The polishing system also includes a pad having at least one protrusion extending from a surface of the pad. The protrusion is configured to contact the polishing film and press the polishing film against the magnetic disk. The protrusion is operable to compress to about the surface of the pad when in contact with the polishing film. Once polishing is complete, the pad retracts from the polishing film and the protrusion extends from the pad, reducing the adhesion force between the pad and the polishing film.
