Zhongxiang Steel Plate Cutting-Laser Cutting Parts Material Processing

Compared with other thermal cutting methods, laser cutting is generally characterized by fast cutting speed and high quality. The specific summary is as follows.
⑴ Good cutting quality
Due to the small laser spot, high energy density and fast cutting speed, laser cutting can achieve better cutting quality.
① The laser cutting incision is narrow, both sides of the slit are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can be achieved.
② The cutting surface is smooth and beautiful, with a surface roughness of only tens of microns. Even laser cutting can be used as the last process without mechanical processing, and the parts can be used directly.

③ After the material is laser cut, the width of the heat-affected zone is very small, and the performance of the material near the cutting seam is almost unaffected. The deformation of the workpiece is small, the cutting precision is high, and the geometry of the cutting seam is good. The cross-sectional shape of the slit is a relatively regular rectangle. The comparison of laser cutting, oxyacetylene cutting and plasma cutting methods is shown in the table
⑵
The cutting material is low carbon steel plate.
⑵ High cutting efficiency Due to the transmission characteristics of laser, laser cutting machines are generally equipped with multiple CNC worktables, and the entire cutting process can be fully CNC controlled. During operation, just by changing the CNC program, it can be used for cutting parts of different shapes, and can perform both two-dimensional and three-dimensional cutting.
⑶ Fast cutting speed
Use a laser with a power of 0 to cut thick mild steel plates at a cutting speed of up to 1/2. For cutting thick polypropylene resin plates, the cutting speed can reach 1/2. Materials do not need to be clamped and fixed during laser cutting, which not only saves tooling fixtures, but also saves auxiliary time for loading and unloading materials.
⑷ Non-contact cutting
During laser cutting, there is no contact between the cutting torch and 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. The laser cutting process has low noise, small vibration and no pollution.
⑸ There are many types of cutting materials
Compared with oxyacetylene cutting and plasma cutting, there are many types of laser cutting materials, including metals, non-metals, metal-based and non-metal-based composite materials, leather, wood and fiber wait. However, different materials have different adaptability to laser cutting due to their different thermophysical properties and laser absorption rates.
