How to protect yourself during the use of the laser cutting machine?

       The role of laser in the processing and manufacturing industry is becoming more and more important and more common, but will such a high-tech technology cause potential harm to the human body? Especially large equipment like laser cutting machine?


       In this regard, many people tend to be daunted when using laser products, and it is even difficult to put laser products into mass production.


       From the fundamental level, the laser cutting machine is generally not harmful to the human body.


       Although the laser cutting machine does not cause any harm to the human body in essence, if it is used improperly during use, it will also cause certain damage to the human body:



1. Eye damage


       When working with a laser cutting machine, workers often like to stare at the cutting head. If they stare at the cutting sparks for a long time, it will cause damage to the eyes and produce a tingling sensation. During the processing of the laser cutting machine, the emitted laser light can concentrate the energy and focus on the retina through the refractive medium of the eye to form an image, so that the energy density on the retina is significantly higher than the incident energy density on the cornea. The upper laser has good monochromaticity and small chromatic aberration in the fundus, so it will cause damage to the cornea or retina.


2. Skin damage


       When the laser hits the skin, if its energy (power) is too large, it can cause skin damage. The damage can be repaired by the tissue, and the function is reduced, but it does not affect the overall functional structure. If the skin is irradiated for a long time, it may cause burns and scars.


3. Respiratory system injury


       When the laser is processing some special metal materials, the high temperature generated by the laser will combine with the gas and produce a large amount of dust. Most of these fumes contain a large amount of chemical components, and the dust will also be suspended in the air. Careless inhalation can cause damage to the human respiratory system. .


      So how should we avoid the damage caused by fiber laser cutting machine?



       1. Necessary protective equipment for the laser cutting machine should be prepared, and protective goggles should be worn to prevent laser damage to human eyes. Other people in the work area should not look directly at the laser during cutting.


       2. Operators should pay attention to eating carrots, bean sprouts, tomatoes, lean meat, animal liver and other foods rich in vitamin AC and protein, which can better protect the eyes.


      3. Corresponding dust removal devices should be equipped, and try to operate in an unobstructed air environment, and wear masks.


      4. When arranging the cutting site, the site and walls of the working environment should be painted dark to reduce radiation.


      5. Do not touch the cut parts immediately after processing to avoid burns due to residual temperature.


      6. Since the laser beam is an invisible beam, do not touch the light path during use to avoid damage to the body.


      7. There are harmful elements (ZnSe) in the focusing lens of the laser cutting machine. Do not touch the lens frequently, and take special treatment after the lens is scrapped. Do not throw it away.
