Many people have heard of laser engraving machines. As an efficient metal and non-metal processing equipment, laser engraving machines have the advantages of good cutting quality and cost savings, which has attracted a lot of attention. Many users are worried that laser engraving machines have radiation. Do laser engraving machines really have radiation? Will this radiation harm our bodies?
Laser engraving machines emit radiation, but the radiation emitted by laser equipment is different from the radiation we are familiar with, so the radiation from laser equipment will not cause harm to the human body.
How is laser generated?
Laser is a type of light emitted by atomic radiation. When an atom transfers from a high energy level to a low energy level, it releases energy and radiation in the form of light. Ordinary light sources come from the spontaneous emission of atoms, while lasers only rely on spontaneous emission for a very short period of time initially. Afterwards, the process is entirely determined by stimulated radiation. Stimulated radiation is the main source of laser light. Compared with ordinary light sources, lasers have good monochromaticity, high brightness, and good directionality. It has a very pure color, almost no divergent directionality, high luminous intensity, and high correlation.
Working principle of laser engraving machine
The laser is produced by the equipment system through pulse discharge, outputting controlled high-frequency pulse lasers to form a beam of light with a certain frequency and pulse width. The formed laser beam is transmitted and reflected through the optical path, forming a high-density light spot that is focused on the surface of the processed object and irradiated onto the surface of the metal workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away molten or vaporized metal, forming smooth cutting seams and completing material cutting.
Laser engraving machine safety protection
Through the above introduction, we understand the principle of laser production. Although laser equipment does not cause harm to the human body during operation, it is important to wear laser goggles correctly. During the processing of laser engraving machines, the laser beam is not visible, but due to its high focusing energy, it will produce high brightness when cutting objects. Wearing laser goggles correctly can effectively protect our glasses from strong light damage caused by laser engraving machines.
