What are the advantages of fiber laser in cutting applications

Superwave Laser Technology Co.,Ltd | Updated: Jun 14, 2018

Low cost and high efficiency fiber laser cutting advantages highlight
(1) operation requirements and maintenance
CO2 laser requires optical path adjustment, and the effect of optical path adjustment will affect the cutting quality. Therefore, the operator needs to have certain skills and needs to maintain the external optical path. The thermal lens effect of YAG solid laser is obvious and needs constant maintenance. Optical fiber laser transmission, no adjustment, no maintenance, high stability, easy operation.
(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, the cutting gap is small, the cutting edge is smooth.
(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 optical 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%. Optical fiber laser consumes only 20-30% of the power of CO2 laser with the same power, and the comprehensive cost is lower.
The optical fiber laser cutting is more precise, the focus can reach 25um, the thermal influence area is small, the cutting seam is small, the workpiece deformation 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.
