Laser is a type of light that, like other natural light, is generated by the transition of atoms (molecules or ions, etc.). But it is different from ordinary light because the laser only depends on Spontaneous emission for a very short time at the beginning, and the subsequent process is completely determined by stimulated emission, so the laser has a very pure color, almost no divergent directionality, extremely high luminous intensity and high coherence.
Laser cutting is achieved by applying 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 pulse laser, forming a beam of 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 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. Each high-energy laser pulse instantly sprays a small hole on the surface of the object. Under computer control, the laser processing head and the processed material move continuously relative to each other according to the pre drawn pattern, which will process the object into the desired shape.
The process parameters (cutting speed, laser power, gas pressure, etc.) and motion trajectory during slitting are controlled by the CNC system, and the slag at the slitting point is blown away by a certain pressure of auxiliary gas.
