Laser cutting machine-features
The advantages of laser cutting:
Advantage Ⅰ——High efficiency
Because of the transmission characteristics of the laser, the laser cutting machine is generally equipped with multiple CNC worktables, and the entire cutting process can be fully CNC. 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.
Advantage Ⅱ-fast speed
The laser with a power of 1200W can cut 2mm thick low carbon steel plate, and the cutting speed can reach 600cm/min; for 5mm thick polypropylene resin plate, the cutting speed can reach 1200cm/min. The material does not need to be clamped and fixed during laser cutting.
Advantage Ⅲ-good cutting quality
1: The laser cutting incision is narrow, the two sides of the incision are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.05mm.
2: The cutting surface is smooth and beautiful, and the surface roughness is only tens of microns. Even laser cutting can be used as the last process without mechanical processing, and the parts can be used directly.
Three: After the material is laser cut, the width of the heat-affected zone is very small, and the performance of the material near the slit is almost unaffected, and the workpiece is small in deformation, the cutting accuracy is high, the geometric shape of the slit is good, and the cross-sectional shape of the slit is relatively Regular rectangle. The comparison of laser cutting, oxyacetylene cutting and plasma cutting methods is shown in Table 1. The cutting material is a 6.2mm thick mild steel plate.
Advantage Ⅳ-Cutting non-contact
There is no direct contact between the torch and the workpiece during laser cutting, and there is no tool wear. Processing parts of different shapes does not need to change the "tool", just change the output parameters of the laser. The laser cutting process has low noise, low vibration and low pollution.
Advantage Ⅴ——More cutting materials
Compared with oxyacetylene cutting and plasma cutting, there are many types of laser cutting materials, including metal, non-metal, metal-based and non-metal-based composite materials, leather, wood and fiber.
