Does a laser cutter harm the body? Generally, it is not harmful to the body, but it is impossible to say that it is absolutely harmless. Nowadays there is a danger of being exposed to cell phones, so any work done can cause harm, can't it? Laser cutting machines are more environmentally friendly than plasma and flame cutting. Plasma cutters produce a lot of dust, smoke and glare when cutting. This requires a matching dust removal device. Laser cutting machine produces less dust when cutting, the light is not strong, the noise is small and environmentally friendly.

Does fiber laser cutting machine have radiation? What harm does it do to the human body?

 Of course, operators or customers who are new to laser cutting machines like to stare at the cutting head. If you see the sparks from the cutting for a long time, it is harmful to your eyes and has a stinging sensation. Generally, some laser cutter manufacturers will provide appropriate goggles. Laser cutting machines are very smart and can be operated unattended without staring at the cutting head, but a word of caution:

 1. The laser is invisible and the laser beam is not visible to the naked eye. Please be careful if you open the hood during maintenance. Do not touch the light path. 

 2, the laser cutting machine focusing lens in the harmful elements (ZnSe), do not often touch the lens, the end-of-life lens should be special treatment, do not throw away.

 In short, the laser cutter can not be said to be harmless, but it is much better than the flame cutter and plasma cutter. As long as you pay attention to the defense, you can basically ignore it.
