Advantages and operation steps of fiber laser cutting machine

The core hub that controls the operation of the entire fiber laser cutting machine. It directs the operation of the entire system according to the needs of the imported vector images. It controls the laser power supply, provides power to the laser, and adjusts the output power of the laser according to requirements. Determine the direction of XYZ movement of the laser direction guide rail and the control of the cooling system according to the vector image of the imported system.

Laser tube is a device that emits laser light. The laser tube is generally composed of three parts: discharge space (discharge tube), water-cooled jacket (tube), and gas storage tube. After the laser tube emits the laser, the marked 1 reflects and reaches 2 and reflects again, and finally reflects 3 to reach the worktable to cut the required items.

Operation diagram of fiber laser cutting machine

First, we will cut the image, generate vector diagram under related software, such as CAD, matlab, and then open it with the operation software of fiber laser cutting machine The corresponding vector diagram, as shown in Figure 4, import the vector diagram into the main control machine, and then the main control machine controls the laser generator to generate laser light, which is reflected multiple times through the reflective lens, and guides the laser light to the worktable, which is controlled by the main control box. Below, the cutting head cuts the material placed on the worktable in a predetermined direction, and the worktable moves up and down, left and right under the action of the servo motor, to finally obtain the desired product. Finally, the cutting machine is reset and returned to the zero position.

The advantages of fiber laser cutting machine

Compared with other thermal cutting methods, laser cutting is generally characterized by fast cutting speed and high quality.

1) Good cutting quality Due to the small laser spot, high energy density, and fast cutting speed, laser cutting can achieve better cutting quality.

2) High cutting efficiency Due to the transmission characteristics of the laser, the fiber laser cutting machine is generally equipped with multiple CNC workbenches, and the entire cutting process can be fully controlled. During operation, only by changing the numerical control program, it can be applied to the cutting of parts of different shapes, which can be used for two-dimensional cutting and three-dimensional cutting.

3) Fast cutting speed Cutting 5mm thick polypropylene resin board, the cutting speed can reach 1200cm/min. And the material does not need to be clamped and fixed during laser cutting, which can save tooling fixtures and auxiliary time for loading and unloading.

4) High brightness of laser: The brightness of solid-state laser can be as high as 1011W/cm2Sr.

5) Laser cutting has a narrow slit, which can save raw materials; the slit has good verticality and a smooth surface; it can be used for part forming and welding without subsequent reprocessing and cleaning treatment; the cutting edge has no burrs and no Mechanical stress. The heat-affected zone is small, and there is basically no deformation; the aspect ratio of laser cutting is large. It can reach about 20:1 for metallic materials and more than 100:1 for non-metallic materials.

6) Laser cutting speed is fast, low noise, almost no pollution, low energy consumption, and there is no 'tool' wear problem in the cutting process. It can be used for a long time and is almost suitable for Taiwan All types of materials can be cut and engraved.

Development direction of fiber laser cutting machine technology

After decades of development, fiber laser cutting machine technology has become more mature, and the future development trend of fiber laser cutting machine is as follows:

, laser cutting will develop in the direction of digitization and intelligent energy. Using the development of intelligent technology, a highly intelligent multifunctional laser processing system has been developed [4].

Second, the development of laser cutting to a multi-functional laser processing center integrates the quality feedback after laser cutting, laser welding and heat treatment, etc., to give full play to the overall advantages of laser processing.

Thirdly, laser cutting will develop in the direction of higher efficiency, precision, and multi-function and high adaptability. The application range of fiber laser cutting robots will become larger and larger, involving more fields.

With the in-depth implementation of the 'Industry 4.0' and 'Made in China 2025' plan in the future, the manufacturing industry will undergo earth-shaking changes, and it will rely more and more on high-tech manufacturing. Laser processing is precisely the

Belonging to this category, due to the advantages of laser processing technology such as high efficiency and high precision, coupled with the application of future intelligent manufacturing technology, fiber laser cutting machine technology will play an increasingly important role in the national industrial system The role of.
