Laser cutting is a technology that uses a high-power laser beam to cut materials. In the process of laser cutting, due to the laser beam focused into a very small spot, the power density at the point of the beam will become very high. the material is quickly heated to the vaporization, it will form to holes after evaporation. As the beam moves, a very narrow (e.g., around 0.1mm) slit will be formed, so as to realize the cutting of materials.
Laser has the characteristics of small spot, extremely high energy density and fast cutting speed, so laser cutting could ensure the high cutting quality.
1. The laser cutting incision is very narrow. Cutting surface is perpendicular to other surface, the accuracy tolerance of cutting parts size can up to ±0.05mm.
2. Cutting surface is smooth and nice, and the roughness is only a few tens of microns. Parts through the process of laser cutting can be used directly, even without mechanical processing.
3. In the process of laser cutting, the heat affected zone (HAZ) of metal materials is very small, so it almost does not affect the material mechanical properties of the cutting seam on both sides. Product after laser cutting is with small deformation and high precision.
