[0002] Laser cutting machines have high operating precision and high processing efficiency, so they have been widely used. Under the irradiation of the laser beam, the surface of the material is quickly heated to the ignition temperature, and then a fierce combustion reaction occurs with oxygen, releasing a large amount of heat, forming small holes filled with steam inside the material, and the small holes are surrounded by molten metal walls. These steam and molten materials are carried away by the auxiliary airflow and float in the workshop, forming dust and smoke;

[0003] The hazards of smoke and dust are easily overlooked by operators. The high temperature generated by the laser acts on the processed materials, producing a large amount of steam and smoke.
