Fiber laser, wavelength 1064ns, good beam quality, high power density, very conducive to the absorption of metal materials, with excellent cutting ability. The laser beam is focused into a very small spot, so that the focal point to achieve a high power density, the material is quickly heated to the degree of vaporization, the kerf width is generally 0.05-0.20mm, positioning accuracy 0.05mm, repeat positioning accuracy 0.03mm, cutting speed up to 10m / min. high conversion efficiency, conversion efficiency of 30% or more, can significantly Save the power consumption when working.
