CNC plasma cutting machine: CNC plasma arc cutting is a processing method that uses the heat of a high temperature plasma arc to melt (and evaporate) the metal part at the cut of the workpiece, and uses the momentum of high-speed plasma to exclude the molten metal to form the cut.
Advantage:
1. Wide cutting area, can cut all metal plates;
2. The cutting speed is fast and the efficiency is high, the cutting speed can reach more than 10m / min;
3. The cutting precision is higher than flame cutting, underwater cutting without deformation, fine plasma cutting is more accurate.
Disadvantages:
1. It is difficult to cut steel plates over 20mm, which requires a plasma power source with high power and high cost.
2. When cutting thick plates, the cut is V-shaped.
Plasma cutting under water can eliminate the noise, dust, harmful gas and arc light generated during cutting, and effectively improve the environment in the workplace. The use of fine plasma cutting has made the cutting quality close to the level of laser cutting. At present, with the maturity of high-power plasma cutting technology, the cutting thickness has exceeded 150mm, which also broadens the cutting range of CNC plasma cutting machines.
