Introduction: before using CO2 laser, optical path adjustment is required. The optical path will directly affect the cutting effect of workpiece, so manual adjustment of optical path and regular maintenance are required.
1. Operation requirements and maintenance
Before using CO2 laser, optical path adjustment is required. The optical path will directly affect the cutting effect of workpiece, so manual adjustment of optical path and regular maintenance are required. YAG solid state laser has obvious thermal lensing effect and needs constant maintenance. Optical fiber laser fiber transmission, no adjustment, no maintenance, high stability, easy to operate.
2. Cutting speed and effect
The cutting speed of fiber laser is 2-3 times that of CO2 laser with the same power. It has prominent advantages in the cutting process of metal plates. It has excellent performance in the other two laser cutting machines with good cutting quality, small gaps and neat edges.
3. Material applicability and application industry
CO2 laser is more widely applicable to materials, while fiber laser is more applicable to metal materials including aluminum, copper and other high reflection materials, which is more in line with the processing requirements of sheet metal manufacturing, 3C home appliance industry and new energy industry.
4. Energy consumption and comprehensive cost
Fiber laser photoelectric conversion rate of more than 30%, with power CO2 laser cutting machine photoelectric conversion rate of about 10% ~ 15%, solid laser photoelectric conversion rate of 3%. The power consumption of fiber laser is only 20-30% of that of CO2 laser with the same power, and the comprehensive cost is lower. Through the comparison, it can be seen that the fiber laser cutting machine in the same conditions of higher efficiency, better cutting effect, maintenance free, but in the purchase cost is slightly higher, large and medium-sized enterprises can give priority to optical fiber equipment.
