What are the advantages of fiber laser in cutting application?

Superwave Laser Technology Co.,Ltd | Updated: May 06, 2018

In laser cutting applications, for example, compare the optical fiber laser cutting machine, CO2 laser cutting machine, the processing characteristics of YAG solid laser cutting machine, to spy out the advantages of fiber laser in the laser cutting application and development potential.

The advantages of low cost and high efficiency fiber laser cutting are highlighted.
(1) operation requirements and maintenance.
The CO2 laser needs to be adjusted by optical path, and the effect of optical path adjustment will affect the cutting quality. Therefore, the operator must have certain skill requirements and need to maintain the external light road. The thermal lens effect of YAG solid laser is obvious and needs constant maintenance. Optical fiber laser fiber transmission, avoid adjustment, maintenance, high stability, easy to operate.
(2) cutting speed and effect.
Fiber laser cutting speed is the same power CO2 laser 2-3 times, especially in sheet metal cutting, fiber laser cutting machine cutting speed has obvious advantages in the three kinds of laser cutting machine. Optical fiber laser cutting machine beam quality is good, cutting edge small, cutting edge level.
(3) material applicability and application industry.
More material broad applicability, CO2 laser and fiber laser for metal materials including aluminum, copper such as the applicability of the reflective material, more in line with sheet metal manufacturing, 3 c electrical appliances industry, new energy industry processing requirements.
(4) energy consumption and comprehensive cost.
The photoelectric conversion rate of the optical fiber laser is over 30%, the photoelectric conversion rate of the same power CO2 laser cutting machine is about 10%~15%, and the photoelectric conversion rate of the solid laser is 3%. Fiber laser power consumption is only 20 to 30% of the same power CO2 laser, and the overall cost is lower.
Optical fiber laser cutting is more precise, the focus can reach 25um, the heat affected area is small, the cutting is small, and the workpiece is small. As a kind of flexible manufacturing mode, fiber laser can be combined with automatic control system, realize the automatic tracking, automatic edge, automatic nesting, greatly enhance the production efficiency, it is widely used in sheet metal cutting, a more excellent performance, can better meet the requirements of precision cutting process. At present in the sheet metal cutting applications, fiber laser has replaced quite a number of CO2 laser and YAG solid state laser, the future development of high power fiber laser breakthrough could speed up the alternative trend.
