Laser Cutting

- Jul 10, 2020-

① The laser cutting incision is thin and narrow, both sides of the slit are parallel and perpendicular to the surface. The dimensional accuracy of the cutting 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 machining, and the parts can be used directly.

③ After laser cutting, the width of the heat affected zone is very small, and the properties of the material near the slit are almost unaffected. Moreover, the deformation of the workpiece is small, the cutting accuracy is high, the geometry of the slit is good, and the cross-section shape of the slit is regular rectangle. The comparison of laser cutting, oxyacetylene cutting and plasma cutting is shown in Table 1. The cutting material is 6.2mm thick low carbon steel plate.
