In recent years, fiber laser cutting machines have become a new favorite in the metal material processing industry. The improvement of cutting technology has greatly promoted the transformation and upgrading of domestic industrial technology. Metal laser cutting machine equipment has gradually been widely used, which has produced varying degrees of influence. Before operating laser cutting, employees must take corresponding pre-job training and self-protection measures, especially eye protection.
Importance of Protection
From the working principle of laser cutting, the damage to the human body is mainly concentrated on the eyes and skin, and necessary protective measures are taken to minimize the damage.
Usually, when you are new to laser cutters, you like to stare at the cutting head. If you look at the sparks from the cut for a long time, it will sting the eyes and feel stinging. During laser cutting machining, the characteristics of laser emission 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 104 to 105 times higher than the incident energy density on the cornea. It may cause damage to the cornea or retina. Therefore, goggles must be worn when operating laser cutting.
When the laser irradiates the skin, if its energy (power) is too large, it will cause skin damage. Of course, damage can be repaired by tissue. Although the function is reduced, it does not affect the overall functional structure. Burns and scarring may occur if exposed to prolonged exposure. , Although the damage is smaller than the eye, it also needs attention. It is recommended to wear protective clothing when production conditions permit.
The high temperature generated by the laser and the gas are used to complete various processing, and at the same time, a large amount of dust will be generated, especially when processing some special metal materials, the generated smoke contains a large amount of chemical components, and the dust will be suspended in the air. Harmful to human body. To reduce the inhalation of harmful dust, a mask should be worn when operating laser cutting.
Recommended protective measures
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.
Operators should pay attention to eat 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 better help humans maintain their eyes and make the human body better . In the case of laser cutting machine radiation, it can better protect the human body.
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.
When arranging the cutting site, try to paint the site and walls of the working environment with dark colors to reduce radiation.
Do not touch the finished parts immediately to avoid burns from residual heat.
