Laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through an optical path system. The laser beam is irradiated onto the surface of the workpiece, causing it to reach its melting or boiling point, while high-pressure gas coaxial with the beam blows away the melted or vaporized metal or non-metal materials.

As the position of the beam relative to the workpiece moves, a cutting seam is ultimately formed in the material, thereby achieving the purpose of cutting.
