What are the advantages of fiber lasers in cutting applications

As one of the core components of high-end manufacturing equipment, fiber lasers are in line with the background of industrial manufacturing transformation and meet the requirements of difficult and changing multi-dimensional processing applications. The advantages of fiber laser material processing make it popular in the market, and it efficiently solves the pain points of high production cost and low production efficiency, so there is a huge market space.


Take the laser cutting application as an example, compare the processing characteristics of fiber laser cutting machine, CO2 laser cutting machine, and YAG solid laser cutting machine to see the advantages and development potential of fiber laser in laser cutting application.

Low-cost and high-efficiency fiber laser cutting has outstanding advantages


(1) Operational requirements and maintenance

The CO2 laser needs to adjust the optical path, and the effect of the optical path adjustment will affect the cutting quality. Therefore, the operator needs to have certain technical requirements and need to maintain the external optical path; the YAG solid-state laser has an obvious thermal lens effect and requires frequent maintenance.

The fiber laser fiber transmission is free of adjustment, maintenance, high stability, and easier to operate.


(2) Cutting speed and effect

The cutting speed of the fiber laser is 2-3 times that of the CO2 laser of the same power, especially in the cutting of thin metal plates, the cutting speed of the fiber laser cutting machine has obvious advantages in the three types of laser cutting machines. Fiber laser cutting machine has better beam quality, smaller cutting gap and smoother cutting edge.


(3) Material suitability and application industry

Fiber lasers are more in line with the processing requirements of sheet metal manufacturing, 3C home appliance industry, and new energy industry.


(4) Energy consumption level and comprehensive cost

The photoelectric conversion rate of fiber laser is more than 30%, the photoelectric conversion rate of the same power CO2 laser cutting machine is about 10-15%, and the photoelectric conversion rate of solid laser is 3%. The power consumption of fiber laser is only 20-30% of the same power CO2 laser, and the overall cost is lower.


Fiber laser cutting is more precise, the focus can be up to 25um, the heat affected zone is small, the slit is small, and the deformation of the workpiece is small. As a flexible processing method, Dineng laser cutting machine can be combined with an automatic control system to realize automatic tracking, automatic edge finding, and automatic nesting, which greatly improves production efficiency. It is widely used in metal cutting, has better performance, and can be better Meet the requirements of fine cutting processing.
