Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting machine with high safety. Background Art

[0002] As we all know, laser cutting machine is a machine that uses high-energy intensive laser beam to cut or engrave materials. It focuses the laser beam on the surface of the workpiece to generate a high-temperature and high-energy-density heat source, which causes the material to partially melt, gasify or burn, thereby achieving cutting, engraving or punching of the material. Laser cutting machines are widely used in metal processing, wood processing, textile cutting, automobile manufacturing, electronic device manufacturing and other fields. They have the advantages of high precision, high efficiency and non-contact processing, and have become an indispensable and important tool in modern manufacturing.
