Abstract

Electroerosion machine for the treatment of turbine rotor vanes consisting of a mobile working head and a container which receives the article to be treated which is immersed in liquid oil at the point of treatment. The article is carried by shafts on support bearings which can be displaced longitudinally alongside the container and can be immobilised in different positions. The machine can thus treat articles of different sizes without changing the container since the articles on the bearings can be moved into the most favourable position with respect to the working head. A system of seals is provided to prevent leakage of oil at the points where the shafts pass through the container walls.
