The radiation brought by the laser cutting machine cannot be underestimated, especially the blinding damage to the human eye. So how do we protect ourselves from radiation damage from laser cutting machines?


1. Eyes


When first contacting a laser cutting machine, people often like to stare at the cutting head. If you stare at the sparks from the cut for a long time, it can cause a stinging sensation in the eyes. In addition, during the processing of the laser cutting machine, the emitted laser can make the energy highly concentrated in space and time, 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 higher than the incident energy on the cornea. The density is increased by 104 to 105; coupled with the good monochromaticity of the laser, the chromatic aberration in the fundus is small, so that very low laser energy irradiation can cause damage to the cornea or retina.


2. Skin


When the laser irradiates the skin, if its energy (power) is too large, it can cause skin damage, and prolonged exposure may cause burns and scars. This type of damage can be repaired by tissue, although the function is reduced, but it does not affect the overall functional structure, and it is much lighter than the damage to the eye, but it must also be paid attention to.


3. Respiratory system


The high temperature generated by the laser cooperates with the gas to complete various processing, and at the same time, a large amount of dust is generated, especially when processing some special metal materials, the generated smoke contains a large amount of chemical components. The dust is suspended in the air and is harmful to the human body when inhaled.


How to avoid the damage caused by the fiber laser cutting machine?


1. Necessary laser cutting machine protective equipment, wear protective glasses to prevent laser damage to human eyes. Others in the work area should not look directly at the laser while cutting.


2. Operators should pay attention to eating more foods rich in vitamin AC and protein such as carrots, bean sprouts, tomatoes, lean meat, animal livers, etc. as appropriate, and often drink green tea, etc., because these foods can help humans better maintain their eyes. So that the human body can better protect the human body under the condition of laser cutting machine radiation.


3. There must be a matching dust removal device, try to operate in an environment with unobstructed air, and wear a mask as much as possible.


4. When arranging the cutting site, paint the site and walls of the working environment with dark colors to reduce radiation.


5. Do not touch the finished parts immediately to avoid burns from residual heat.
