Laser cutting is making use of focused high-power laser beam irradiation of the workpiece, so that the material is rapidly 

melting, vaporization, ablation or reach the point of ignition, meanwhile ，with the help of the high-speed air blown to blown away the molten material, so that to achieve cut off the  workpieces.
Compared to CNC punch, Laser cutting with the advantage of truncated smooth and  high efficiency.
