  1. Introduction

    The fiber laser cutting machine is a laser cutting machine which uses the fiber laser generator as the light source.

    Fiber laser is a new development of the international fiber laser output high energy density, and gathered on the surface of the workpiece, so that the workpiece is exposed to the ultra-fine focus of the area of instantaneous melting and gasification, through the CNC mechanical system moving spot irradiation to achieve automatic cutting. Compared with the large-scale gas lasers and solid-state lasers have obvious advantages, has gradually developed into high-precision laser processing, laser radar systems, space technology, laser medicine and other fields of important candidates.

    Fiber laser Cutting machine It can do plane cutting, also can do bevel cutting processing, and edge neat, smooth, suitable for metal plates and other high-precision cutting processing, coupled with the mechanical arm can be three-dimensional cutting instead of the original imported five-axis laser. Compared to ordinary carbon dioxide laser cutting machine to save space and gas consumption, photoelectric conversion rate is high, is a new product of energy saving and environmental protection, is also one of the leading technology products in the world.

    Fiber laser Cutting machine is more advantageous than CO2 laser cutting machine:

    1 Excellent beam quality: focus spot smaller, cutting lines more fine, more efficient, better processing quality;

    2 extremely high cutting speed: it is twice times of the same power CO2 laser cutting machine;

    3 Very high Stability: the use of the world's top imported fiber lasers, stable performance, the key components of the service life of up to 100,000 hours;

    4 High Electro-optic conversion efficiency: Optical fiber laser cutting machine photoelectric conversion efficiency of about 30%, is CO2 laser cutting machine 3 times times, energy saving and environmental protection;

    5 extremely low cost of use: The whole machine consumes only for similar CO2 laser cutting machine $number;

    6 Very low maintenance cost: No laser working gas, optical fiber transmission, no reflection lens, can save a lot of maintenance costs;

    7 Product operation and maintenance convenience: optical fiber transmission, no need to adjust the light path;

    8 Ultra-strong flexible light effect: compact size, tight structure, easy to flexible processing requirements.

    Of course, compared with carbon dioxide laser cutting machine, fiber cutting range is relatively narrow. Because the wavelength of the reason, it can only cut metal materials, non-metallic is not easily absorbed by it, thus affecting its cutting range.

    Advantages compared with YAG laser cutting machine:

    1 cutting speed: Fiber laser cutting machine speed is 4-5 times the YAG, suitable for a large number of processing and production

    2 Use Cost: Fiber laser cutting machine cost less than YAG solid laser cutting

    3 Photoelectric conversion Efficiency: The photoelectric conversion efficiency of fiber laser cutting machine is about 10 times times of that of YAG

    The corresponding fiber laser price is higher, so the fiber laser cutting machine price higher than the YAG laser cutting confidential a lot, but more than carbon dioxide laser cutting confidential much lower. But the rate of sexual comparison is indeed the highest among the three.
