  • Automated polishing process for mechanical parts in titanium or titanium alloy
    Patent number: 7029367
    Abstract: The present invention pertains to an automated polishing process for semi-finished mechanical parts in titanium or titanium alloy, using a machine with abrasive belt mounted on a tangential contact wheel driven in rotation at a determined speed and applied at a determined pressure, the wheel travelling with respect to the part's surface at a determined rate, characterized by the fact that the abrasive belt consists of superabrasive grains in industrial diamond or cubic boron nitride. The process is applied to geometric conforming of jet engine fan or compressor blades.
    Type: Grant
