Laser cutting machine is a device that uses a laser beam to cut materials. Its working principle is to focus a laser beam to generate high temperature on the surface of the material, thereby cutting the material into the desired shape. Laser cutting machines are usually composed of lasers, focusing systems, cutting and control systems, etc. The laser generates a laser beam, and the focusing system focuses the laser beam on the surface of the material, cutting the material into the desired shape. The control system controls the movement and cutting process of the laser beam. Laser cutting machines are widely used for cutting materials such as metals, plastics, and glass, with advantages such as high precision and fast speed.
