  • Patent number: 11883928
    Abstract: A mechanism for polishing includes a polishing member, an eccentric member coupled to the polishing member, and a driving member coupled to the eccentric member. The driving member drives the eccentric member to rotate to move the polishing member to reciprocate in the one-dimensional direction, so that when a relative position between the polishing mechanism and the workpiece is fixed, the polishing member polishes a workpiece by translating a polishing surface. A method for the polishing process, applied by a polishing device, is also disclosed. By using the polishing mechanism, the entirety of the polishable surface of the workpiece can be covered, and collapsed edges of the workpiece are avoided.

    Abstract: This invention relates generally to an improved rotor for a pneumatic abrading or polishing tool, such as an orbital abrading or polishing tool, and more particularly to such a rotor having a wear-resistant vane slot. A power abrading or polishing tool, such as a pneumatic orbital abrading or polishing tool, includes a motor having a rotor that transmits a rotational force to a carrier part having an abrading or polishing head attached thereto. The rotor is contained in a motor housing which includes an inlet passage and one or more exhaust passages. Compressed air or other suitable gas enters the motor housing through the inlet passage and causes the rotor to rotate within the motor housing. As the rotor rotates, vanes slide in and out of slots in the rotor, creating sealed chambers or compartments between adjacent vanes. As the compressed gas expands within these compartments, it pushes on the vanes, causing the rotor to rotate and the vanes to slide in and out of their vane slots.

    Abstract: A superfinishing method of a tapered roller bearing, including the steps of: rotating an outer ring of the tapered roller bearing about a center axis thereof; inserting a straight-shaped superfinishing stone from a front face of outer ring; and slidingly contacting a leading end face of the superfinishing stone with a taper-shaped raceway surface formed in an inner peripheral surface of the outer ring to thereby superfinish the raceway surface. The superfinishing stone is inclined outwardly of the front face of outer ring with respect to a vertical line of the raceway surface.

  • Patent number: 6506106
    Abstract: Apparatus for sharpening a razor blade with a motor actuated sharpening member mounted in a housing with a slot for receiving the razor head and a cradle assembly for engaging the distal end of the razor handle to hold the razor head in the slot. A carriage assembly holds the sharpening member opposite to the slot with its sharpening surface engaging the cutting edge of a razor blade secured in the razor head. A drive assembly driven by a motor operated by a timing circuit causes repetitive movement of the sharpening surface for a predetermined period of time.

  • Publication number: 20010024927
    Abstract: An apparatus for the in situ superfinishing of crankshaft thrust bearing surfaces includes an oscillator, an oscillation arm connected to the oscillator such that the oscillation arm is reciprocable by the oscillator, a caliper disposed on the oscillation arm remote from the oscillator, and at least two abrasive pads disposed on the caliper. The oscillation arm facilitates the extension of the arm into the engine to cause the abrasive pads to engage the bearing and to abrasively superfinish the surfaces of the bearing. A method for the in situ superfinishing of the surfaces of the bearing includes operably locating a superfinishing apparatus adjacent the engine, extending the abrasive pads into the engine, causing the abrasive pads to engage the surfaces to be superfinished, and oscillating the abrasive pads in contact with the surfaces to be superfinished.

  • Patent number: 6200413
    Abstract: A system and method for polishing spherical shaped devices is disclosed. The system includes a carrier and an enclosure. The carrier has two projections so that when a device is placed between the projections, it contacts the carrier at two contact points. The enclosure matingly engages with the carrier so that it also contacts each device at two contact points. A movement system, such as a motor, provides relative movement between the carrier and the enclosure so that the four contact points polish each device. Also, the relative movement moves each device so that the device's entire outer surface is polished by the apparatus.

  • Patent number: 6193590
    Abstract: Magnetic recording media are provided having separately textured data and read/write head landing zones. Separating these zones on the recording surface allows independent optimization of the topology to maximize both recording characteristics and mechanical durability. The landing or contact start stop zone has an average surface roughness greater than that of the data zone. Preferably, a transition zone extends between the contact start stop zone and the data zone, the transition zone varying between the two in average surface roughness. Preferably, the contact start stop zone is textured first, followed by the data zone, thereby ensuring uniform stiction performance. Texture machines for producing such zone texturing and texturing methods are also provided.

  • Patent number: 6113753
    Abstract: A method is provided for processing a metal foil sheet to produce magnetic recording media. The method comprises providing an elongate metal foil sheet having a first side and a second side. The sheet is advanced through a plurality of processing stations in equal unit length segments such that each segment receives the same treatment to form a magnetic recording medium from each segment. Method are also provided to prepare the foil surfaces by polishing, texturing, cleaning, and stress relieving, to coat the prepared surfaces with at least one metal layer, to finish the coated layers by buffing, burnishing, and lubricating, and to form disk units from the prepared, coated and finished surfaces.
