ABSTRACT:
An apparatus for the working of materials in a vacuum by means of an electron beam. A vacuum machining facility incorporating a first chamber which includes a longitudinal gap which determines a vacuum tight area around the machining line of the parts to be machined, a flexible sealing strip to plug the gap and a second leakproof chamber which houses an electron gun. The second chamber abutting the first chamber, includes an orifice located close to the gap through which the electron beam passes. The second chamber is movable on the first chamber along the gap. An apparatus is included which moves the plugging strip out of and to the side of the gap in the proximity of the orifice, the plugging strip being fully housed inside the gap except in the region close to the orifice.
