I: Generally speaking, it is harmless to the body. It is impossible to say that there is absolutely no harm, and it is possible to do any work. Laser cutting is much more environmentally friendly than plasma cutting and flame cutting. There is a lot of dust, smoke and strong light when the plasma cutting machine cuts, which requires a supporting dust removal device. The laser cutting machine produces less dust, less light and less noise when cutting. More environmentally friendly. Of course, operators who only touch the laser cutting machine usually like to stare at the cutting head. If you look at the sparks generated by cutting for a long time, it will hurt your eyes and sting. Generally, some laser cutting machine manufacturers will be equipped with corresponding glasses to protect their eyes. The laser cutting machine is highly intelligent and can be operated unmanned without staring at the cutting head. But remind the landlord to pay attention to the following points: 1) laser is invisible light, 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 element (ZnSe) in the focusing lens of the laser cutting machine should not come into contact with the lens frequently, and the discarded lens should be specially treated and not thrown about. 3) I don't know what the landlord is processing. If it is carbon steel or stainless steel, it is not a big problem. If a large number of aluminum alloys are processed, the cut dust will be suspended in the air, which is harmful to human body after inhalation. There is also a strong reflection when cutting aluminum plates, and the cutting head needs a protective device, otherwise it is easy to break down. In short, the quality requirements of laser cutting machine operators are higher than those of flame cutting machine and plasma cutting machine operators, but as long as they learn, they will be very relaxed. Ⅱ: As a brand-new processing method, laser cutting machine has been widely used in leather, textile and garment industries because of its advantages of accurate, fast, simple operation and high degree of automation. Nowadays, it is also widely used in metal processing. Compared with the traditional cutting method, the laser cutting machine not only has low price and low consumption, but also has the characteristics of safe operation and simple maintenance because laser processing has no mechanical pressure on the workpiece, so the effect, accuracy and cutting speed of the cut products are very good. In recent years, the laser cutting machine has developed rapidly and has gradually replaced the traditional technology. Wuhan Jinyun Laser has developed very well, and now it has been listed.
