Features of fiber laser generator

• The MAX fiber laser has high electrical-optical conversion efficiency, and the conversion efficiency is more than 30%. The medium power fiber laser uses water cooling, which can greatly save power consumption during operation, save operating costs, and achieve the highest production efficiency;
• The laser only needs electrical energy during operation, and does not need extra gas to generate laser, and has the lowest operation and maintenance cost;
• The fiber laser adopts semiconductor modular and redundant design. There is no optical lens in the resonant cavity, which does not require startup time. It has the advantages of no adjustment, maintenance, and high stability. It reduces the cost of accessories and maintenance time. This is a traditional laser. incomparable;
• The output wavelength of the fiber laser is 1.07 um, which is 1/10 of the CO2 wavelength. The output beam quality is good, the power density is high, which is conducive to the absorption of metal materials, and has excellent cutting ability, so as to minimize the processing cost
• The optical transmission of the whole machine is through optical fiber transmission, and does not require complex light guide systems such as reflectors.

Gas and water system

• The gas path system of fiber laser cutting machine comprises two parts, one being cutting gases provided to cutting head which comprise compressed air, oxygen and nitrogen, and the other being auxiliary gas which is dry and clean compressed air
• The high-pressure nitrogen passes through the high-pressure pipe and is controlled by the high-pressure solenoid valve to directly enter the cutting head. At the same time, it is equipped with a manually adjustable high-pressure relief valve. The nitrogen pressure can be adjusted when cutting different plate thicknesses to save nitrogen consumption
• The cutting section is not required high quality, high-pressure air can be used for cutting, and the pipeline is shared with high-pressure nitrogen, and the three-way ball valve is used for switching, which is convenient and fast, and can save the cost of cutting auxiliary gas
• The waterway system includes two parts: a part of the cooling water comes out of the chiller, enters the laser, cools the laser through the radiator inside the laser, and returns to the chiller. This part belongs to the low temperature part; Enter the QBH through the laser and return to the chiller

Laser cutting head

Cutting head and follower
