Laser cutting refers to the energy released when the laser beam irradiates the surface of the workpiece to melt and evaporate the workpiece, which has achieved the purpose of cutting and carving. It uses the laser beam emitted from the laser generator to focus into high-power density laser beam irradiation conditions through the optical path system. The laser heat is absorbed by the workpiece material, and the workpiece temperature rises sharply. After reaching the boiling point, the material begins to vaporize and form holes. With the high-pressure gas flow, with the movement of the relative position between the beam and the workpiece, the material finally forms a slit.

Specific laser cutting details of laser cutting machine:
Laser cutting is realized by using high power density energy generated by laser focusing. Under the control of the computer, the controlled repetitive high-frequency pulse laser is output through the discharge of the pulse laser, forming a beam with a certain frequency and pulse width. The pulse laser beam is transmitted and reflected through the optical path, and focused on the surface of the processed object through the focusing lens group, forming a fine, high-energy density light spot. The focal spot is located near the surface to be processed, melting or vaporizing the processed material at an instant high temperature.
A high-energy laser pulse will instantly splash a small hole on the surface of the object. Under the control of the computer, the laser processing cutting head and the processed material will conduct continuous relative movement according to the pre-designed figure, so that the object will be processed into the desired shape.
