Does laser cutting generate radiation?
The laser cutting machine has radiation, but the radiation emitted by the laser equipment is different from the radiation we are familiar with at ordinary times, so the radiation of the laser equipment will not cause harm to human body.
How is laser produced?
Laser is the light radiated by atoms. When atoms transition from high energy level to low energy level, they will release energy and radiate it in the form of light. Ordinary light sources are derived from spontaneous emission of atoms, while laser only depends on spontaneous emission in a very short time at first, and the subsequent process is completely determined by stimulated radiation. Stimulated radiation is the main light source of laser. Compared with ordinary light sources, laser has good monochromaticity, high brightness and good directivity. It has very pure color, almost no divergent directivity, extremely high luminous intensity and high coherence.
Working principle of laser cutting machine
Controlled by the equipment system, the fiber laser discharges through pulses, and outputs a controlled repetitive high-frequency pulse laser to form a beam with a certain frequency and pulse width. The formed laser beam is transmitted and reflected through the optical path and passes through the focusing lens group to form a high-density spot, which is focused on the surface of the processed object and irradiates the surface of the metal workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal to form a smooth slit, so as to complete the cutting of the material.
Safety protection of laser cutting machine
Through the above introduction, we understand the generation principle of laser. Although the radiation generated by the laser equipment in the operation process will not cause harm to human body, we should still pay attention to wearing laser goggles correctly in the operation process. Although the laser beam is invisible in the processing process of the laser cutting machine, due to its high focusing energy, it will produce high brightness light when cutting objects, and wear laser goggles correctly during operation, It can effectively protect our glasses from the strong light generated by the laser cutting machine.
