laser cutting machine

 The laser cutting machine is to use a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material quickly melts, vaporizes, ablates, or reaches the ignition point, while blowing away the molten material with the help of the high-speed airflow coaxial with the beam, thus realizing the workpiece cut. Laser cutting is one of the thermal cutting methods. The specific advantages of laser cutting compared to other thermal cutting methods can be summarized as follows.

Good cutting quality: Due to the small laser spot, high energy density, and fast cutting speed, laser cutting can obtain a better cutting quality. ① laser cutting kerf is thin and narrow, the two sides of the cut are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ± 0.05mm. ② the cut surface is clean and beautiful, and the surface roughness is only a few tens of microns, even laser cutting can be used as the last process, without mechanical processing, the parts can be used directly. ③ material after laser cutting, the width of the heat-affected zone is very small, the performance of the material near the cut is almost unaffected, and the workpiece deformation is small, the cutting accuracy is high, the geometry of the cut is good, and the cross-sectional shape of the cut presents a more regular rectangle.
