What is the difference between fiber laser cutting machine and YAG laser cutting machine?

The technology of fiber laser cutting machine is higher than that of YAG laser cutting machine that the cutting quality is good and the efficiency is high. But the price is much higher than YAG's.

YAG laser cutting machine has low cost and can cut highly reflective materials, such as aluminum, copper and other non-ferrous metal materials that cannot be cut by fiber laser cutting machines. However, YAG laser cutting machine is a low-power laser cutting machine, which can only cut sheet materials below 8mm. The fiber laser cutting machine can achieve very high power in a very small package.

The resonant cavity of the fiber laser cutting machine has no optical lens so that it does not need any adjustment or maintenance.

The cutting speed of the fiber laser cutting machine is 4 to 5 times faster than that of YAG laser cutting machine. Therefore, it is available for mass production.

The photoelectric conversion efficiency of the fiber laser cutting machine is about 10 times higher than that of YAG laser cutting machine.

What is the difference between CO₂ laser cutting machine and fiber laser cutting machine?

Fiber laser cutting machines have gradually replaced CO₂ laser cutting machines and traditional processing methods.

CO₂ laser cutting machine generates the laser beam, which is transmitted through the reflector. However, fiber laser cutting machines are transmitted through diodes and fiber optic cables.

The appearance of fiber laser cutting machine is more compact due to the different laser transmission structure, thereby saving workshop space.

Due to complete solid-state digital module and single design, fiber laser cutting machine has higher electro-optical conversion efficiency. The actual utilization rate of each power supply unit of CO₂ laser cutting machine is about 8% to 10%, while fiber laser cutting machine is about 25% to 30%. It increases the energy efficiency to more than 86%.

Fiber laser cutting machine has the characteristics of short wavelength, which improves the absorption of the cutting material to the beam. It enables to cut materials like brass, copper and non-conductive materials.

Due to the purity of the CO₂ gas, the resonant cavity of the CO₂ laser cutting machine will be polluted and needs to be cleaned regularly. The reflect mirror needs to be maintained and calibrated. Fiber laser cutting machine is environmental-friendly.

What are the cutting advantages of fiber laser cutting machine?

The positioning accuracy of the fiber laser cutting machine is 0.05mm and the repeat position is 0.03mm.

The fiber laser cutting machine has a narrow slit. The laser beam is focused into a small spot so that it can reach a high-power density.

The cutting surface of the fiber laser cutting machine is smooth that there are no burrs.

The cutting speed can reach 10m per min, which is much faster than others.

The fiber laser cutting machine has good cutting quality. The cutting edge is little affected by heat without thermal deformation of the workpiece. The collapse of the material formed during punching and shearing is completely avoided.
