    Abstract: A high speed polishing device useful for polishing a large number of miniature components, such as multi-layer electronic components, is disclosed. In various embodiments of the present invention, a vertical planetary ball mill or other barrel polishing device is modified to rotate polishing containers having a modified interior cavity structure. This interior cavity provides a smooth, gradually curved interior sidewall that improves circulation within the container during high-speed vertical polishing rotation. The improved circulation results in polishing for a larger number of components placed within the container and in less time than existing polishing container structures. In further embodiments, the containers are rotated around a generally tilted axis positioned at an angle between entirely vertical and horizontal positions. Rotation about a tilted axis further reduces collisions and increases relative polishing movement within the container.

The first abrasive is then removed and a second abrasive is added to the vessel. The inner vessel is then rotated, again at high speed, with the second abrasive. The resulting tools have reduced surface anomalies.

  • Patent number: 6821191
    Abstract: An apparatus and process of surface finishing golf balls prior to painting is provided. The apparatus and process make use of nylon loops as a finishing material that is used to abrade the surface of adjacent moving golf balls. Optionally, the abrading process between the nylon loops and the surface of the golf balls may be carried out in the presence of a continuous stream of water. As water is removed from the processing equipment, the removed water carries with it abraded material. The process provides for improved adhesion of the paint to the surface of the golf ball.

  • Patent number: 6764384
    Abstract: An arrangement and method for precision machining of rotationally symmetrical, disk or ring-shaped components. The arrangement includes a container which is open at the top and mounted such that it is able to vibrate. An unbalanced rotor causes the container to vibrate in a rotation-induced manner and has a drive. The container is filled with an abrasive substance including a multitude of abrasive bodies and a liquid. A device for fixing the component is also arranged in the container which has a rotationally symmetrical shape and is arranged in line with a vertical axis. The container also includes a rigid fixing device for horizontally positioning the component.

  • Patent number: 6705010
    Abstract: A method of reducing the force required to insert an elastomeric seal in a cavity of a metallic member includes tumbling the member in a tumbling machine with media to decrease the surface roughness of the member. Preferably, the tumbling step includes decreasing the surface roughness of the metallic member at least a portion of the member defining an entrance to the cavity. The method is particularly useful for reducing the force required to insert fuel injectors having top O-rings into fuel rail cups.

  • Publication number: 20040038627
    Abstract: A method of removing parting line flash from a molded golf ball by use of low temperature cryogenic deflashing apparatus is disclosed. The cryogenic deflashing apparatus incorporates a rotating basket wherein the golf balls are placed and therein agitate them such that each ball will be evenly exposed to a recirculating blasting media. The low temperature environment causes the very thin gauge (0.003″) parting line flash to become embrittled relative to the ball and is deflashed by the blasting media, which comprises plastic pellitized shot.
