Fiber laser cutting is a hot cutting method which makes use of the focused high power density laser beam as the main heat source to iiluminate the workpiece, cause the irradiation materials rapidly melting, evaporation and ablation or reach the ignition point.
At the same time with the aid of high-speed airflow which coaxial with the laser beam to blow away molten material, so as to realize the cutting of the workpiece.
With the mature and perfect technology of high power fiber laser generator in recent years, its application field is expanding continuously, and the fiber laser cutting machine has become the hot spot of industry research and development.

Laser cutting power & speed
The fiber laser cutting has a great influence on cutting thickness, cutting speed, cutting width and cutting quality.
Generally speaking, the large the laser power, the thicker the cutting board and the faster-cutting speed.
Under certain plate thickness and cutting speed, there is an optimal range of laser power
The roughness of the cutting surface is the smallest in this range.
The surface roughness of the workpiece increases when it deviates from the optimal power range
Low processing efficiency and increase cost.

Advantages of fiber laser cutting 

1.Superior performance on metal materials

  • Boost in cutting speed when cutting thin material (eg. 1mm in thickness, a fiber laser can cut 3 times faster than that of a traditional laser).
  • Stunning cutting performance (high precision, narrow cutting seam,smooth cutting surface, etc).
  • Typically suitable for thin and thick metal materials by different power.

2. Less investment and more returns

  • High electro-optic conversion efficiency(25%-40%), low power consumption.
  • No routine laser maintenance needed, low maintenance cost.
  • Fiber laser generator lifetime 100,000+ hrs of continual running.
  • Rigid machine body structure, 10+ years lifespan.

3. User friendly, convenient operation

  • Suitable for feature processing all kinds of workpiece graphics,easily arranged, modified, giving the best material utilization and the fast cutting speeds.

4. Safety and environmental friendly

  • Auxiliary cutting gas(N2, O2), minimal pollution, low noise, protection design, electricity safety.
