The advantages of fiber lasers in cutting applications

Jessica 2017-06-23 13:42:50
(1) operation requirements and maintenance
  The CO2 laser needs to be adjusted by the light path, and the effect of the adjustment of the optical path will affect the cutting quality. Therefore, the operator needs to have certain skill requirements and need to maintain the external light road. The thermal lens effect of YAG solid laser is obvious and needs to be maintained frequently. Optical fiber laser optical fiber transmission, no adjustment, maintenance, high stability, easier 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, cutting gap 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 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 the solid laser is 3%.The fiber laser consumes only 20 to 30% of the power of the CO2 laser, and the overall cost is lower.
  Optical fiber laser cutting is more precise, the focus can reach up to 25um, the heat affected area is small, the cut is small and the work piece 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.
