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.
Claims7
A vacuum machining facility incorporating a first large chamber including a longitudinal gap having a V-shaped cross section which determines a leakproof area around the machining line of the parts to be machined;
- a flexible strip to plug this gap;
- a second leakproof chamber which houses a machining tool, this second chamber including an orifice located close to the gap;
- sealing systems located around the orifice between both chambers, a drive unit to move the said second chamber on the first chamber and along the gap;
- a system designed to move the plugging strip away from the gap close to the orifice, this arrangement being featured by the fact that the strip is fully housed inside the gap, its upper face being level with the outer face of the first chamber.
