Since 1970, CO2 laser machine has long development and is always used to cut metal sheet. But rapid development of fiber laser machine is changing the process of metal sheet cutting.
So which one is suitable for you?
FIBER LASER CUTTING MACHINE
Fiber laser light is created by banks of diodes. The light is channeled through fiber optic cable. The amplified light, on exiting the fiber cable is collimated or straightened and then focused by a lens on the material to be cut.
- No mirrors or moving parts in the beam generating source.
- Lower maintenance and operating costs.
- Lower electricity consumption. On average, consumption of 3kW fiber laser machine is up to one third of the consumption of a 4kW CO2 laser machine.
- Able to cut reflective material without fear of damaging the machine.
- Higher speeds when cutting thin material under 5mm thickness.
- Longer service intervals.
- High safety required. Because laser light can pass straight through the retina
CO2 LASER CUTTING MACHINE
The CO2 is gas molecular laser. Electricity is run through the gas to produce light. With a transparent mirror on one end and a reflective mirror on the other end, the produced beam is emitted through the transparent mirror. The beam is reflected through beam path mirrors and focused by the cutting head onto the material to be cut.
- Cutting speed in a straight line is faster than a fiber laser cutting machine, especially in materials above 5mm thickness.
- If only need to cut thicker material, CO2 laser cutting machine is faster.
- CO 2激光切割机的表面质量在切割较厚的材料时更好，因为CO2激光切割机的光斑尺寸比光纤激光切割机宽。
- 切割厚度超过5mm的材料时，每个零件的成本将降低。
- CO2激光切割机更适合切割非金属材料，如织物，皮革，亚克力，塑料等。切割反射材料时，激光头内部的光学部件会损坏，因为大部分光束会被材料反射
- There is no risk of irreparable damage to the retina.
总之：
光纤激光切割机是切割5mm厚度以下材料的最佳选择
CO2激光切割机更灵活，切割5mm以上的材料时切割质量更好。
