  • Method Of Producing A Bearing Housing From A Worn Housing, And Fixture Implementing Such A Method
    Publication number: 20050120558
    Abstract: 14A method of producing a bearing housing from a worn housing extending along an axis and having an intermediate portion; four end portions located at opposite axial ends of the intermediate portion; and an inner shield, the ends of which are integral with the intermediate portion and one end portion. According to the method, the intermediate portion and the shield are detached from the end portions and replaced with a new shield and a new intermediate portion, whereas the end portions are used again; and, to weld the new intermediate portion to the salvaged end portions, a fixture is provided for ensuring the necessary parallelism, squareness, flatness, concentricity, and dimensions of the portions.

  • Method of detecting the position of an inner surface of a workpiece on a machine tool, and machine tool implementing such a method
    Patent number: 6647351
    Abstract: The position of the inner surface of a hollow metal workpiece on a machine tool is detected by connecting an operating member of the machine, preferably a tool, to a first terminal of an electric power source; connecting the inner surface to a second terminal of the power source; moving the operating member gradually towards the inner surface to detect the emission of a signal generated by an emitting device interposed between one of the terminals and the inner surface, and corresponding to a condition in which initial contact is established between the operating member and the inner surface; and determining the position of the operating member at the instant the signal is emitted.
