Because laser cutting is easy to use and its safety has been improved, it is widely used, such as tube fiber laser cutting machine, a classification of laser cutting machine, which is also widely used, such as some metal pipes. If you want to improve the working efficiency of the tube fiber laser cutting machine, you need to do the following.
1. The influence of focus position adjustment on cutting quality Since the laser power density has a great influence on the cutting speed, the choice of lens focal length is an important issue. After the laser beam is focused, the spot size is proportional to the focal length of the lens. After the beam is focused by the short focal length lens, the spot size is very large.
is small, the power density is very high at the focal point, which is very beneficial for material cutting.
2. The influence of the auxiliary gas pressure on the cutting quality. Under normal circumstances, the cutting of materials requires the use of auxiliary gas. The problem mainly involves the type and pressure of the auxiliary gas. Usually, the auxiliary gas is ejected coaxially with the laser beam to protect the lens from contamination and blow away the slag at the bottom of the cutting area.
3. The influence of laser output power on the quality of cutting damage For continuous wave output lasers, the size of the laser power and the quality of the mode will have an important impact on the cutting. In actual operation, a higher power is often set to obtain a higher cutting speed, or to cut thicker materials. But the beam pattern is sometimes more important, and when the output power is increased, the pattern often becomes slightly worse. It can often be found that higher power density is obtained at the focal point under the condition of less than high power, and better cutting quality is obtained.
