Laser cutting machine is a device that uses high-energy laser beams to cut materials. Its working principle is to use the high energy of the laser beam to heat the material to the melting point or gasification point, and then blow away the melted or vaporized material through high-pressure gas to achieve cutting. Laser cutting machines have the advantages of high precision, fast speed, and good cutting quality, and are widely used for cutting materials such as metals, plastics, glass, ceramics, etc.
