Is the laser cutting machine harmful to human body? Generally speaking, there is no harm to the body, but it is impossible to say that there is absolutely no harm. Now there is a risk of radiation when using a mobile phone, so it is possible to do any work, isn't it? Laser cutting machine is much more environmentally friendly than plasma cutting and flame cutting. There is a large amount of dust, smoke and strong light when plasma cutting machine is cutting, which requires supporting dust removal device. The laser cutting machine produces less dust, light is not very strong, and noise is also very small. It is environmentally friendly.
Of course, the operators or customers who only contact the laser cutting machine usually like to look at the cutting head. If the laser cutting machine looks at the sparks generated by cutting for a long time, it will hurt the eyes and cause a tingling sensation. Generally, some laser cutting machine manufacturers will provide corresponding glasses to protect eyes. The laser cutting machine is highly intelligent and can be operated without people. It is unnecessary to look at the cutting head, but we should pay attention to the following points:
1. The laser is invisible, and the laser beam is invisible to the naked eye. If you open the hood during maintenance, you must pay attention. Don't accidentally touch the light path. It's not fun to meet.
2. The harmful elements (ZnSe) in the focusing lens of the laser cutting machine should not be frequently contacted with the lens. The discarded lens should be specially treated and should not be thrown around.
In a word, the laser cutting machine can not be said to have no harm to the human body, but it is much better than the flame cutting machine and the plasma cutting machine. As long as you pay attention to the defense during the work, it can be basically ignored.
The laser cutting machine has played a great auxiliary role in the processing of metal products, improving the work efficiency, cancelling the contract of human resources and production costs, but there will also be many small problems during the use of the cutting machine, such as edge burning. What are the reasons for this?
Cutting machine will produce a lot of heat when processing sheet metal parts. If the heat is not diffused in time, it will lead to the appearance of edge burning. The heat accumulation can be reduced by increasing the pressure of auxiliary gas, setting the conditions as high peak output and low frequency pulse conditions. When using air as auxiliary gas, it is the same as when using nitrogen, and overburning will not occur, but it is easy to form slag at the bottom. Therefore, it is necessary to set the conditions as high auxiliary gas pressure, high peak output, and low frequency pulse conditions.
When laser cutting machine is used to process small holes, the outside of the hole can be cooled. However, the small hole inside the single hole has a small space where heat can be diffused and the heat is too concentrated, resulting in over burning, slag hanging, etc. In addition, during thick plate cutting, the molten metal accumulated on the material surface during perforation and the heat accumulation will lead to the disorder of auxiliary air flow and excessive heat input, which will lead to over burning and edge burning.
