Nowadays, with continuous technological innovation, there are more types of laser cutting machines on the market. We know that different types of laser cutting machines have different advantages when cutting different materials. Let’s introduce you to three common laser cutting machines. What are the advantages of the machine.   At present, there are mainly three kinds of most common laser cutting machines, YAG solid laser cutting machine, fiber laser cutting machine and CO2 laser cutting machine. The advantages of these three laser cutting machines are as follows:   1. YAG solid-state laser cutting machines have the characteristics of low price and good stability, but the low energy efficiency is generally <3%. The output power of the current products is mostly below 600W, due to the small output energy , Mainly used for punching and spot welding and cutting of thin plates. Its green laser beam can be applied under pulse or continuous wave conditions. It has short wavelength and good light concentration. It is suitable for precision machining, especially for hole machining under pulse. It can also be used for cutting, welding and lithography, etc. . The wavelength of YAG solid laser cutting machine laser is not easy to be absorbed by non-metal, so it cannot cut non-metal materials. What YAG solid laser cutting machine needs to solve is to improve the stability and life of the power supply, that is, to develop a large-capacity, long-life optical pump Excitation light sources, such as the use of semiconductor light pumps, can greatly increase the energy efficiency. 2. Because it can transmit through the optical fiber, the degree of flexibility is unprecedentedly improved, the failure point is less, the maintenance is convenient, and the speed is extremely fast. The effect of wavelength is poor quality when cutting thick plates. The wavelength of fiber laser laser cutting machine is 1.06um, which is not easily absorbed by non-metal, so it cannot cut non-metal materials. The photoelectric conversion rate of fiber laser is as high as 25%, and the advantages of fiber laser in terms of electricity consumption and supporting cooling system are quite obvious. According to international safety standards, laser hazard levels are divided into four levels. Fiber lasers are the most harmful to the human body due to their short wavelength, which is the most harmful to the eyes. For safety reasons, fiber laser processing requires a completely enclosed environment. As an emerging laser technology, fiber laser cutting machine is far less popular than CO2 laser cutting machine.  3, CO2 laser cutting machine, can stably cut carbon steel within 20mm, stainless steel within 10mm, and aluminum alloy below 8mm. The CO2 laser has a wavelength of 10.6um, which is relatively easy to be absorbed by non-metals. It can cut non-metal materials such as wood, acrylic, PP, and organic glass with high quality, but the photoelectric conversion rate of the CO2 laser is only about 10%. The CO2 laser cutting machine is equipped with a nozzle for blowing oxygen, compressed air or inert gas N2 at the beam exit to improve the cutting speed and the smoothness of the cut. In order to improve the stability and life of the power supply, the discharge stability of the high-power laser must be solved for the CO2 gas laser. According to international safety standards, the laser hazard level is divided into 4 levels, and the CO2 laser is the least hazardous level.   Wuhan Gaoneng Laser Equipment Manufacturing Co., Ltd. is a high-tech enterprise integrating Ru0026D, production and sales of professional laser complete sets of equipment.
