(1) Good cutting quality

① The laser cutting incision is thin and narrow, with both sides of the cutting seam parallel and perpendicular to the surface;

② The cutting surface is smooth and beautiful, with a surface roughness of only a few tens of micrometers. Even laser cutting can be used as the final process, without the need for processing, and the parts can be directly used;

③ After laser cutting the material, the width of the heat affected zone is very small, and the performance of the material near the cutting seam is almost unaffected.

In addition, the workpiece deformation is small, the cutting accuracy is high, the geometric shape of the cutting seam is good, and the cross-sectional shape of the cutting seam is regular rectangular.

(2) High cutting efficiency. Due to the transmission characteristics of laser, laser cutting machines are generally equipped with

Prepare multiple CNC workbenches, and the entire cutting process can be CNC controlled. During the operation process, only by changing the NC program can it be suitable for cutting parts of different shapes. Not only can two-dimensional cutting be carried out, but three-dimensional cutting can also be achieved.

(3) Fast cutting speed.

(4) Non contact cutting: During laser cutting, the cutting torch does not come into contact with the workpiece and there is no tool wear. To process parts of different shapes, there is no need to change the "tool", just change the output parameters of the laser. Laser cutting technology has the advantages of low noise, low vibration, and no pollution.

(5) There are many types of cutting materials. Compared with oxyacetylene cutting and plasma cutting, laser cutting has a wide range of materials, including metal, non-metal, metal matrix and non Metal matrix composite, leather, wood and fiber. However, different materials exhibit different laser cutting adaptability due to their different thermophysical properties and laser absorption. Using CO2 laser, the laser cutting performance of various materials is shown in Table 2. Most laser cutting machines are controlled by CNC programs or made into cutting robots. Laser cutting, as a precision machining method, can cut almost all materials, including two-dimensional or three-dimensional cutting of metal sheets. In the field of automobile manufacturing, the cutting technology of spatial curves such as roof windows has been widely applied. Volkswagen uses a laser with a power of to cut complex body panels and various curved parts. In the field of aerospace, laser cutting and processing of aerospace parts, including engine flame tubes, titanium alloy thin-walled gearboxes, aircraft frames, titanium alloy skins, wing trusses, tail wall panels, helicopter main rotors, and aerospace shuttle ceramic insulation tiles, are also widely used in the field of non-metallic materials. Such as silicon nitride, ceramics, quartz, etc; Flexible materials such as cloth, paper, plastic sheets, rubber, etc.
