Laser light is a kind of light, which, like other natural light, is produced by the transition of atoms (molecules or ions, etc.). But it is different from ordinary light in that the laser only relies on spontaneous radiation in the first very short time, and the subsequent process is completely determined by the excitation radiation, so the laser has a very pure color, almost no divergent directionality, and extremely high luminous intensity and high coherence.
Laser cutting is achieved by applying high power density energy generated by laser focusing. Under the control of the computer, the laser is discharged through the pulse, so as to output the controlled repetitive high-frequency pulse laser to form a beam with a certain frequency and a certain pulse width. The pulse laser beam is transmitted and reflected by the optical path and focused on the On the surface of the processed object, tiny, high-energy-density light spots are formed, and the focal spot is located near the surface to be processed, melting or vaporizing the processed material at an instantaneous high temperature. Each high-energy laser pulse instantly sputters a small hole on the surface of the object. Under the control of the computer, the laser processing head and the material to be processed perform continuous relative motion according to the pre-drawn graphics, so that the object will be processed. desired shape.
The process parameters (cutting speed, laser power, gas pressure, etc.) and movement trajectory during slit are controlled by the numerical control system, and the slag at the slit is blown off by auxiliary gas with a certain pressure.

How to judge the cutting quality of laser cutting machine

Different cutting materials will also affect the accuracy of the laser cutting machine. Under the same circumstances, the precision of cutting stainless steel and cutting aluminum will be very different, the cutting precision of stainless steel will be higher, and the cutting surface will be smoother.

What are the laser cutting machine processes?

During the laser gasification cutting process, the surface temperature of the material rises to the boiling point temperature so fast that it is enough to avoid melting caused by heat conduction, so part of the material is vaporized into steam and disappears, and part of the material is ejected from the bottom of the slit by the auxiliary gas The flow blows away. Very high laser powers are required in this case.
