1. Operation requirements and maintenance
The CO2 laser needs to adjust the optical path before use. The condition of the optical path will directly affect the cutting effect of the workpiece, so the optical path needs to be manually adjusted and maintained regularly. The YAG solid laser has obvious thermal lens effect and requires regular maintenance. The fiber laser has optical fiber transmission and does not require adjustment. , Maintenance-free, highly stable and 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. Its advantages are particularly prominent in the cutting process of metal sheets. It has excellent performance among the other two laser cutting machines. It has good cutting quality, small gaps and neat edges. .
3. Material applicability and application industries
CO2 lasers are more suitable for a wide range of materials, while fiber lasers are suitable for metal materials including aluminum, copper and other highly reflective materials, which are more in line with the processing requirements of sheet metal manufacturing, 3C home appliance industry, and new energy industry.
4. Energy consumption level and comprehensive cost
The photoelectric conversion rate of fiber laser is more than 30%, the photoelectric conversion rate of CO2 laser cutting machine with the same power is about 10% to 15%, and the photoelectric conversion rate of solid laser is 3%. The power consumption of fiber lasers is only 20-30% of that of CO2 lasers with the same power, and the overall cost is lower. Through comparison, it can be seen that fiber laser cutting machines have higher working efficiency under the same conditions, better cutting effects, and are maintenance-free, but the purchase cost is slightly higher. Large and medium-sized enterprises can give priority to fiber optic equipment.
