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.
Claims21
A process of manufacturing a mechanical part, said process comprising the following steps:
- rough-polishing a semi finished part comprising titanium, wherein during said rough polishing, material between 0.1 mm and 0.8 mm thick is removed;
- and
- finish-polishing said rough-polished part, said finish-polishing being performed with an abrasive belt comprising super abrasive grains and mounted on a tangential contact wheel driven in rotation, wherein during said finish-polishing, material between 0.01 mm and 0.2 mm is removed.
