## Abstract

This invention concerns a machine for working metals using an electron beam, characterized in that the gun and the enclosures occupy a fixed position in relation to one another, the gun being connected to each of the enclosures through a duct provided with a sealing valve a stage for electromagnetic deflection of the beam being provided between the gun and the ducts so as to deflect the beam successively towards the enclosures through the ducts.

## Claims

### Claim 1

Machine for working metals using an electron beam, comprising an electron gun and a plurality of enclosures associated with means for creating a vacuum, these enclosures containing workpieces to be worked on to which the beam produced by the gun is directed, said machine characterised in that the gun and the enclosures occupy a fixed position in relation to one another, the gun being connected to each of the enclosures through separate ducts provided with a sealing valve, a stage for electromagnetic deflection of the beam being provided between the gun and the ducts so as to deflect the beam successively towards the enclosures through the ducts.

### Claim 2 (depends on 1)

Machine according to claim 1, characterized in that each duct is provided with a beam-deflecting device at its junction with the enclosure.

### Claim 3

A machine for working metals, using an electron beam and comprising;
an electron gun,
a plurality of enclosures, each having means for providing a vacuum,
said enclosures containing work pieces to be worked on to which the beam produced by the gun is directed,
said gun and enclosures occupying a fixed position in relation to one another,
separate ducts for interconnecting the gun with each of the enclosures,
and electromagnetic deflection means for providing deflection of the beam between the gun and the ducts so as to deflect the beam selectively to each duct and associated enclosure.

### Claim 4 (depends on 3)

A machine according to claim 3 wherein each duct is provided with a beam deflecting device at its junction with the enclosure.

### Claim 5 (depends on 3)

A machine according to claim 3 further comprising a sealing valve associated with each respective duct.

### Claim 6 (depends on 3)

A machine according to claim 3 wherein said duct is fixedly connected to each of the enclosures through separate ducts.

### Claim 7

A method for working means using an electron beam comprising the steps of;
providing an electron gun,
providing a plurality of enclosures,
positioning the electron gun in fixed position relative to said enclosures which are also fixed in position,
connecting said gun through ducts to each respective enclosure,
and deflecting the beam between the gun and the ducts to deflect the beam from one enclosure to another.
