Generally speaking, it is not harmful to the body. (It is impossible to say that there is absolutely no harm. There is a possibility of harm in any work)

Laser cutting is much more environmentally friendly than plasma cutting and flame cutting.

When cutting with a plasma cutting machine, there is a lot of dust, thick smoke and strong light, which requires a matching dust removal device.

The laser cutting machine produces less dust when cutting, the light is not very strong, and the noise is very small. More environmentally friendly.

Of course, most operators who are new to laser cutting machines like to stare at the cutting head. Staring at the sparks generated by cutting for a long time can cause damage to the eyes and cause a stinging sensation. Generally, some laser cutting machine manufacturers will provide corresponding eye protection glasses. The laser cutting machine is highly intelligent and can be operated unmanned without having to stare at the cutting head.

But the author is reminded to pay attention to a few points:

1) Laser is invisible light, and the laser beam is invisible to the naked eye. If you open the hood for maintenance, you must pay attention. Don't accidentally touch the light path. It's not fun to run into.

2) The harmful element (ZnSe) in the focusing lens of the laser cutting machine should not be in frequent contact with the lens. The scrapped lens should be disposed of specially and should not be thrown away.

3) I don’t know what materials the poster is processing. It's not a big problem if it's carbon steel or stainless steel. If aluminum alloys are processed in large quantities, the cutting dust will be suspended in the air and be harmful to the human body if inhaled. There is also a strong reflection when cutting aluminum plates, so the cutting head needs a protective device, otherwise it is easy to malfunction.

In short, laser cutting machine operators have higher quality requirements than flame cutting machine and plasma cutting machine operators, but as long as you learn it, it will be very easy.
