What is the difference between laser cutting machine and plasma cutting machine

At present, the most popular cutting technologies on the market are laser cutting machines and plasma cutting machines. However, many companies that need cutting equipment will get confused when choosing. What is the difference between a plasma cutting machine and a laser cutting machine? First of all, we have to get it Know the cutting principles of these two cutting machines. 

Principle of laser cutting machine: 　　

The energy released when the laser beam irradiates the surface of the work piece melts and evaporates the work piece, so as to achieve the purpose of cutting. The laser has directivity without divergence, with extremely high luminous intensity, high coherence, high intensity and high directivity, so that the cutting speed is high, the precision is high, the cutting quality is good, and the cutting gap is narrow; the laser cutting heat affected zone is small , The deformation is extremely small, safe, clean, and pollution-free during cutting, which greatly improves the working environment of the operator. 　　

Principle of plasma cutting: 　　

Using the heat of the high-temperature plasma arc to locally melt and evaporate the metal at the incision of the work piece, and then use the momentum of the high-speed plasma to remove the molten metal to form the incision processing method. 　　From the working principle, we can find that the laser cutting does not damage the processed work piece, while the plasma cutting work piece will have large or small damage, especially if there is a problem with the plasma cutting machine gun nozzle during the cutting process, the plate will have obvious defects. And because the laser beam can be focused into a small spot, the cutting seam to the work piece is very narrow, and the cutting seam of plasma cutting is larger than that of laser cutting machine. 　　

In addition, the laser cutting machine has high cutting accuracy, the laser cutting positioning accuracy is 0.05mm, and the repeat positioning accuracy is 0.02mm, while the plasma cutting is lower than the laser cutting machine. And the speed of laser cutting machine is much faster than that of plasma cutting machine. 　　

Knowing these, I believe everyone has a general understanding of the two cutting machines. In conclusion, the laser cutting machine must be a booster for the future industrial development, and HE Laser will help you move forward!
