Advantages of laser processing

Laser cutting uses a focused high-power-density laser beam to illuminate a workpiece, causing the material to be irradiated to rapidly melt, vaporize, ablate, or reach a flash point. At the same time, the molten material is blown off by a high-speed airflow coaxial with the beam, thereby cutting the workpiece. Laser cutting is one of the hot cutting methods. Compared with other thermal cutting methods, laser cutting has several advantages.

1. Good cutting quality. Laser cutting can achieve better cutting quality due to small laser spot, high energy density and fast cutting speed. The laser cutting slit is narrow, the slits are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.05mm.

2. Smooth and beautiful cutting surface. The surface roughness is only a few tens of micrometers, and even laser cutting can be used as the last process. No machining is required, and the parts can be used directly.

3. After laser cutting, the width of the heat-affected zone is small, the performance of the material near the slit is almost unaffected, and the deformation of the workpiece is small, the cutting precision is high, the geometry of the slit is good, and the shape of the slit cross-section is relatively regular.

High cutting efficiency. Due to the transmission characteristics of the laser, the laser cutting machine is generally equipped with multiple CNC working tables, and the whole cutting process can realize numerical control. During operation, it is only necessary to change the numerical control program to suit for different shapes parts, which can perform 2d cutting and 3d cutting.
