Is It Harmful to The Human Hody to Use a Laser Cutting Machine?

Jul 07, 2022

Is it harmful to the human body to use a laser cutting machine?

Many people have heard of laser cutting machines. As high-efficiency metal processing equipment, laser cutting machines have the advantages of good cutting quality and cost savings, and have received widespread attention. Many users worry that laser cutting machines have radiation. Does laser cutting machines really have radiation? Will this radiation cause harm to our body?

Does laser cutting produce radiation?

Laser cutting machines have radiation, but the radiation emitted by laser equipment is different from the radiation we are familiar with, so the radiation of laser equipment will not cause harm to the human body.

How is the laser produced?

Laser light is stimulated by atoms, and when atoms transition from a high energy level to a low energy level, energy is released and radiated in the form of light. Ordinary light sources originate from the spontaneous radiation of atoms, while lasers only rely on spontaneous radiation for a very short period of time at first, and the subsequent process is completely determined by stimulated radiation, which is the main light source of lasers. Compared with ordinary light sources, lasers Good monochromaticity, high brightness and good directionality. With very pure color, almost no divergence of directionality, very high luminous intensity and high coherence.

Working principle of laser cutting machine

The fiber laser is controlled by the equipment system to discharge through pulses, and outputs a pulsed laser with controlled repetition of high frequency to form a beam of 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 light spot, which is focused on the surface of the processed object and irradiated to the surface of the metal workpiece, so that the workpiece reaches the melting point or boiling point, and the high-pressure gas coaxial with the beam is at the same time. The material is cut by blowing away molten or vaporized metal to create a smooth kerf. This is how a metal laser cutter works.

Laser cutting machine safety protection

Through the above introduction, we understand the principle of laser generation. Although the radiation generated by the laser equipment during operation will not cause harm to the human body, it is still necessary to wear laser goggles correctly during the operation. Although the laser beam is invisible during the processing of the laser cuter, due to its The focusing energy is high, which will produce high-brightness light when cutting objects. Wearing laser goggles correctly during operation can effectively protect our glasses from the strong light generated by the laser cutting machine.
