Why does the laser cutting machine instead of plasma cutting machine

CNC plasma cutting machine is a kind of commonly used thermal cutting equipment, its principle is the use of high temperature plasma arc cutting calories make partial melting of the metal artifacts slit, at the same time, with the aid of high-speed plasma momentum to exclude the molten metal, and make them form the incision. Compared with the CNC laser cutting machine, plasma cutting of maintenance cost and manufacturing cost far more, so now it is the trend of 'fall' step by step.
CNC laser cutting machine is the combination of the numerical control technology and laser technology, it is a kind of advanced cutting equipment metal processing industry. It is in the process of machining, do not need to open mold, also do not need to adjust the light path, as long as the design on the computer need to cut the pattern, then press the key, cutting can easily cut out of the workpiece to be cut. And the cut surface is very smooth, no burr.
