Description

Technical Field

[0001] The utility model relates to a laser cutting workbench. Background Art

[0002] Laser cutting is the use of a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize or reach the ignition point, and at the same time using a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. It is one of the thermal cutting methods for cutting workpieces.

[0003] During laser cutting, the workpiece needs to be placed on a workbench and supported by densely arranged spikes on the workbench to facilitate the discharge of molten material during the laser cutting process.
