How big is the laser cutting machine radiation

This kind of radiation of the laser cutting machine is very small, just a slight amount of no effect at all. During the processing of the fiber laser cutting machine, the characteristics of the laser emitted can make the energy highly concentrated in space and time. The refractive medium of the eye is focused on the retina to form an image, and the energy density on the retina is increased by 104~105 compared with the incident energy density on the cornea; the laser has good monochromaticity and small chromatic aberration in the fundus. The above-mentioned characteristics result in extremely low laser energy irradiation that can cause damage to the cornea or retina.

During the cutting process of the laser cutting machine, the light beam is focused on a small focal point through the lens of the cutting head, achieving high power density at the focal point, and the cutting head is fixed on the z-axis. At this time, the hot star input by the beam far exceeds a part of the heat reflected, conducted or diffused by the material, and the material is quickly heated to the melting and vaporization temperature. At the same time, a high-speed airflow of molten and vaporized material is blown from the coaxial or non-coaxial side to form holes through which the material is cut. With the relative movement of the focus and the material, a continuous narrow gap is formed in the hole to complete the cutting of the material.

During the processing of laser cutting machine, according to the characteristics of the emitted laser, the energy can be highly concentrated in space and time, and the refractive medium of the eye can be focused on the retina to form an image. The energy density on the retina is 104~105 higher than the incident energy density on the cornea, and the monochromaticity is good, and the chromatic aberration on the fundus is small. According to the above characteristics, extremely low laser energy irradiation can cause damage to the cornea and retina.

As you know, operating in the machining industry is very risky. The mechanical noise, dust, dust and operation errors generated by the processing can cause slight or heavy personal injury to the operators. In order to avoid personal threats to operators, the following suggestions encourage operators to perform standardized operations.

　　 1. During the processing of the laser cutting machine, the characteristics of the emitted laser light can make the energy highly concentrated in space and time, and the refraction medium of the eye is focused on the retina to form an image. The energy density on the retina is increased by 104 to 105 than the incident energy density on the cornea. The monochromaticity is good, and the chromatic aberration of the fundus is small. The above characteristics can cause cornea and retina damage.

　　 2. To reduce the radiation of the laser cutting machine, you need to use laser protective glasses. It is specially designed for equipment and can effectively reduce radiation. Therefore, the operator does not need to worry when using it, and can safely cut the workpiece. In addition, there are various types of laser protective glasses, such as composite type, absorption type, reflection type, and diffraction type.

　　 3. Reducing the radiation of the laser cutting machine workers can protect themselves, such as eating more radiation-resistant food to effectively resist radiation. Workers in contact with cutting machines generally like to stare at the cutting head. Watching the sparks from cutting for a long time will hurt the eyes and sting. The laser cutting machine is highly intelligent and can be operated unmanned, without the operator staring at the cutting head. When cutting with a plasma cutting machine, there is a lot of dust, dense smoke, and strong light, and a dust removal device is required. When cutting objects, the laser cutting machine produces less dust, not too strong light, low noise, and environmental protection.
