  • Patent number: 9174316
    Abstract: A workpiece is fixed by a retracting mechanical chuck mounted on a spindle head of a five-axis control machining center. The apparent outer diameter of the workpiece is increased by a jig. Clamp surfaces of the jaws and a support surface of the jig are formed on the machining center. A cutting tool is mounted on a spindle by an automatic tool exchanger. The workpiece is rotated about an axis to grind an end surface of the workpiece to approximately a predetermined target shape, which is a spherical surface. A grinder is then mounted on the spindle by the automatic tool exchanger, and the grinder is set relative to the workpiece by five-axis control such that the inclination angle, the offset amount, etc. satisfy a predetermined relationship according to the desired grinding. The grinder is then fed in the Z-axis direction to form the spherical surface by grinding.

  • Patent number: 9039489
    Abstract: An automated method for reconditioning a plurality of digital discs within a reconditioning apparatus is disclosed. The method comprises holding the digital discs in a load area, and then transferring each of the digital discs from the load area to at least one workstation with a disc transfer mechanism. The method also comprises reconditioning each of the digital discs transferred to the workstation with at least one worktool operable to remove a portion of the protective coating of each of the digital discs without removal of the data underlying the protective coating. The method further comprises transferring each of the digital discs from the workstation to an unload area with the disc transfer mechanism, and then holding the digital discs in the unload area for manual retrieval. Advantageously, the digital discs may be automatically reconditioned within the reconditioning apparatus without manual manipulation of the digital discs during the reconditioning process.

    Abstract: The method is for sharpening a blade. An automatic sharpening apparatus is provided that has a holder. A blade is placed into the holder. A grinding-wheel driving motor, in operative engagement with a wheel on a spindle, rotates a grinding wheel. A grinding assembly motor moves the grinding wheel in an x-direction towards the blade. A linear motor moves the grinding wheel from a first position to a second position in a z-direction without moving the grinding-wheel driving motor. The rotating grinding wheel engages the blade. The grinding wheel sharpens the blade.
