Laser cutting is achieved by using the high-power density energy generated by laser focusing. Under the control of a computer, the laser is discharged through pulses to output a controlled repetitive high-frequency pulsed laser, forming a beam of light with a certain frequency and pulse width. The pulsed laser beam is transmitted and reflected through the optical path and focused on the surface of the processed object through a focusing lens group, forming fine, high-energy density light spots. The focal spots are located near the surface to be processed and melt or vaporize the processed material at high temperatures in an instant.

A 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 irradiates the surface of the workpiece, causing it to reach its melting or boiling point, while the high-pressure gas coaxial with the beam blows away the melted or vaporized metal.

As the beam of light moves relative to the workpiece, it ultimately forms a cutting seam in the material, thereby achieving the purpose of cutting.
