  • Machining methods using superabrasive tool
    Patent number: 7896728
    Abstract: A tool for use in an abrasive machining process has a body extending along a central longitudinal axis from a first end to a tip end. An abrasive material is located on the tip end. The body has a tip end protuberance. An abrasive material is located on the protuberance. A body lateral surface has, over a radial span of at least 20% of a radius of the protuberance, a continuously concave longitudinal profile diverging tipward.
    Type: Grant

  • Point superabrasive machining of nickel alloys
    Patent number: 7144307
    Abstract: A process for point superabrasive machining of a nickel based material comprising the steps of providing a tool having a grinding surface coated with a superabrasive material, orienting the tool relative to a surface of the nickel based material to be machined so that there is point contact between the surface to be machined and the grinding surface, and forming a part by removing material at the point contract by rotating the tool. The tool comprises an enlarged portion, a tip portion, and a first shaft portion extending from the enlarged portion to the tip portion, the first shaft portion and the tip portion being coated with an abrasive material, and the first shaft portion having a constant diameter.
