What are the advantages of laser cutting compared to other thermal cutting methods?

Specifically summarized as follows:

⑴ Good cutting quality: Due to the small laser spot, high energy density, and fast cutting speed, laser cutting can achieve good cutting quality.

① The laser cutting incision is narrow, with both sides of the cutting seam parallel and perpendicular to the surface, and the dimensional accuracy of the cutting part can reach ± 0.05mm.

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 mechanical processing, and the components can be directly used.

③ After laser cutting, the width of the Heat-affected zone of the material is very small, and the performance of the material near the kerf is almost unaffected. Moreover, the deformation of the workpiece is small, the cutting accuracy is high, the geometry of the kerf is good, and the cross section of the kerf is rectangular. The comparison of laser cutting, oxyacetylene cutting, and plasma cutting methods is shown in Table 1. The cutting material is 6.2mm thick low-carbon steel plate.

⑵ High cutting efficiency. Due to the transmission characteristics of laser, laser cutting machines are generally equipped with multiple CNC workstations, and the entire cutting process can be fully CNC controlled. When operating, simply changing the CNC program can be used to cut parts of different shapes, which can perform both two-dimensional and three-dimensional cutting.

⑶ Fast cutting speed: Use a laser with a power of 1200W to cut 2mm thick low-carbon steel plates, with a cutting speed of up to 600cm/min; Cut 5mm thick polypropylene resin board with a cutting speed of up to 1200cm/min. The material does 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.
