Abstract

A laser processing machine has a processing area and a laser processing device. A workpiece can be processed by the laser processing device at a processing location via emission of laser radiation to generate a processing product. An environment of the processing area is shielded against the laser radiation by a protective housing. The processing product can be moved in a discharge direction to pass a boundary of the protective housing that is flexible in the discharge direction. A product rest, arranged below the processing location in the vertical direction and extending in the discharge direction, functions to store the processing product. In the vertical direction below the processing location, the protective housing extends in the discharge direction, forming an extension with which the protective housing extends over the product rest. The boundary limits the extension in the discharge direction and is arranged above the product rest.

Dependent claims

A laser processing machine comprising:

a processing area having a protective housing;
a laser processing device arranged in the processing area and by which a workpiece arranged in the processing area can be processed at a processing location to produce a processing product with an emission of laser radiation, wherein an environment of the processing area is shielded against the laser radiation by the protective housing, and wherein the processing product is movable in a discharge direction to be discharged from the protective housing to pass a boundary of the protective housing that is flexible in the discharge direction;
and
a product rest configured to store the processing product, wherein the product rest is arranged in a vertical direction below the processing location and extends in the discharge direction,
wherein, vertically below the processing location, the protective housing is enlarged with an extension being formed in the discharge direction and extends with the extension over the product rest, and
wherein the boundary of the protective housing is arranged at an end of the extension of the protective housing in the discharge direction and in a vertical direction above the product rest.
