Advantage of fiber laser in laser cutting
- Jul 18, 2017 -


As one of the core devices of high-end laser equipment, fiber laser fits kinds of industrial manufacturing, high degree and large changes applications.

The fiber laser is wildly used and with big market in kinds of industries, for the high efficiency and low cost. Compare with other CO2 laser cutting and YAG laser cutting, the fiber laser cutting with following advantage:

 (1) Low operational requirements and maintenance cost

CO2 lasers need to adjust the optical path, for it will affect the cutting quality, so the operator must have a certain skill requirements, and also need external optical path maintenance; YAG solid laser need maintenance often; but fiber laser with free adjustment, maintenance-free, high stability, easier operation.

(2) Cutting speed and effect

Fiber laser cutting speed is 2-3 times the same power CO2 laser, especially in the metal sheet cutting; fiber laser cutting machine with the highest speed among all kinds of cutter. Fiber laser cutting machine with good beam quality, the cutting with small gap, and smooth edge.

(3) Material applicability and application industry

CO2 lasers are more widely apply with kinds of materials, and fiber lasers main used for metal materials, including aluminum, copper and other high-reflective material.

(4) Energy consumption and comprehensive costs

Fiber laser conversion rate is more than 30%, but the CO2 laser with same power with the conversion rate of only about 10% to 15%, solid-state laser photoelectric conversion rate is3%. Fiber laser power consumption is only 20-30% of the same power CO2 laser, the combined cost is lower.

Cutting with fiber laser is more precision, focusing focus up to 25um, small heat affected area, small slits, and small deformation of work piece. As a flexible processing method, fiber lasers can be combined with automatic control system to achieve automatic tracking, automatic search edge, automatic nesting material, greatly enhance the production efficiency, its metal sheet cutting widely used, the performance is better, can better meet the fine Cutting processing requirements. Fiber lasers have replaced a considerable portion of CO2 lasers and YAG solid-state lasers in the field of sheet metal cutting applications, and future breakthroughs in high-power fiber lasers will likely accelerate this alternative.
