Abstract:
1. A laser head for a laser processing machine comprising: a housing defining a conical beam space and an axis of a laser beam; a cup-shaped nozzle head mounted on the housing having an opening aligned with the conical beam space; a nozzle disk mounted for rotational movement around a nozzle disk axis relative to the nozzle head, wherein the nozzle disk comprises at least two nozzles and rotation of the nozzle disk selectively positions the at least two nozzles between the conical beam space and a nozzle head opening; and, an eccentric disk rotatably mounted relative to the nozzle head around an eccentric disk axis, wherein the eccentric disk carries the nozzle disk axis in a position spaced from the eccentric disk axis and rotation of the eccentric disk relative to the nozzle head laterally moves the nozzle disk axis and thereby, the nozzle disk.
