Laser cutting machine, as a class of high precision sheet metal processing, and the processing method, has been widely used and sheet metal processing, kitchen utensils and appliances, elevators, elevator, automotive, aviation, machinery manufacturing and other fields, is known as the third industrial revolution after the steam engine, computer, work in laser cutting of the original, the use of laser cutting machine or there are many need to pay attention to the places, the harm of human body, for example, the harm of human body are mainly concentrated in to eyes and skin, and take the necessary protective measures can effectively prevent the use of personnel of physical harm.
1, the eye injuries in laser damage, the serious injury of the body in the eyes. Laser wavelength in the visible and near-infrared light, eye refractive medium absorption rate is low, high transmission rate and refractive media focus ability, The concentrated force) To be strong. High strength of the visible and near-infrared light enters the eye through the human eye refractive media, accumulate the light on the retina. A lot of light in the retina in the moments together, cause retinal photoreceptor cell layer temperature rise rapidly, so losing light-sensitive photoreceptor cells solidification degeneration necrosis. Laser cutting machine operators need to wear goggles when using the laser cutting machine, goggles belongs to the resin material, with selling sunglasses in the same way, the market can effectively reflect the laser beam diffuse reflection.
2, skin damage
the body due to the physiological structure has very sensitive skin touch, pain, temperature, and other functions, constitute a complete protective layer. And the skin is composed of multiple level of organization, in each layer has different cells. When the laser according to the skin, as its energy ( Power) When too much can cause skin damage, of course, by the tissue repair damage ovens, although function declined, but does not affect the overall function structure, and the damage to the eyes. But it must be caused take seriously. For skin damage, it is recommended that the operator to wear long sleeve clothes, prevent laser direct cause skin burns to the skin.
