Is laser radiation and harmful to human body? Is laser cutting machine harmful to people? In fact, laser does not do much harm to human body, but it is impossible to say that there is no harm at all. Electronic products and mechanical equipment will have a little radiation. Even our daily mobile phones have radiation hazards, so it is impossible to work completely harmless.

Laser cutting machine processing than the previous flame cutting and plasma cutting to environmental protection, plasma cutting machine processing will have a large amount of dust, smoke, strong light, plasma cutting machine must be equipped with dust and smoke removal equipment, and laser cutting machine processing will not have so much dust and smoke, light is relatively weak, noise is also very small. Of course, even if the light is very small, it can not be fixed on the sparks produced by cutting. If you look at it for a long time, it will cause certain damage to the eyes and will show obvious tingling feeling. Generally, the manufacturers of laser cutting machine equipment will be equipped with corresponding goggles. Laser cutting machine is a high intelligent equipment produced in civilized society. It is operated by computer without staring at the cutting head. But there are also a few precautions to remind you.

1. The laser is invisible to the naked eye. If you open the protective cover of the machine during maintenance, you must pay attention not to touch the light path, or close the equipment before maintenance.
2. The focus lens of laser cutting machine contains elements harmful to human body (ZnSe). Do not touch the lens frequently, and the damaged lens should not be thrown around. It needs special treatment.
3. For different cutting materials, the required equipment will be different. If cutting aluminum, the laser head must be equipped with a protection device, otherwise it will be prone to failure, because aluminum is a high reflective material. If it’s cutting aluminum alloy, it’s better to equip dust suction equipment, because the cutting dust will float in the air, and the human body will inhale too much dust, which will be harmful to the human body. Stainless steel and iron will be fine. Of course, it’s better to equip dust suction equipment. There will be some dust more or less when cutting, no matter what material it is.

In a word, the laser cutting machine will not directly cause great harm to the human body, of course, it can not be said that there is no harm, but compared with plasma and flame cutting, it is much better. As long as you pay attention to protection and operate in strict accordance with the manufacturer’s instructions, those injuries can be ignored.
