Abstract
A laser beam machining process and apparatus, applicable to laser beam perforation and cutting, in which a laser beam is directed onto a wall (4) of a component (6) to be machined from one side of the said wall and emerges on the other side thereof following the machining operation. According to the invention, a disk (16) which is opaque to the laser beam is placed on the other side of the wall on the path followed by the laser beam when it emerges and performs a rotary movement, so as to stop the emerging laser beam and in this way protect the walls (8) adjacent to the machined wall against the impacts of the emergent laser beam.
Claims6
Process for machining by laser beam, according to which the laser beam is directed onto a wall of a component to be machined from one side of said wall and emerges on the other side thereof after machining, said process being characterized in that a disk opaque to the laser beam is placed on said other side of the wall on a path followed by the laser beam when said laser beam emerges and is given a rotary movement, so as to stop an emergent laser beam which emerges from the wall to be machined and thus protect a wall located adjacent to the machined wall against impingement of said emergent laser beam.
Apparatus for machining by laser beam, comprising:
- means for creating the laser beam and directing it onto a wall of a component to be machined from one side of said wall, the laser beam emerging from the other side of said wall after machining,
- a disk opaque to the laser beam and placed on said other side of the wall on a path followed by the laser beam when the laser beam emerges from the wall being machined, and
- means for rotating the disk, so as to stop an emergent laser beam which emerges from the wall being machined and thus protect a wall located adjacent to the machined wall against impingement of the emergent laser beam.
