[0002] The fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as a light source. It can focus the laser beam on the surface of the workpiece, causing the area on the workpiece irradiated by the ultra-fine focal spot to instantly melt and vaporize to achieve the cutting effect.

If the scraps are not cleaned in time, they will accumulate on the workbench, affecting the normal use of the fiber laser cutting machine. Therefore, they need to be recycled and reused. However, the existing fiber laser cutting machines cannot screen the dust and scraps when discharging materials, and staff need to perform manual screening later, which has low work efficiency; and the discharging mechanism is not easy to remove from the workbench.
