Fiber Laser Cutting Machine
The laser beam is focused by the lens in the cutting head and directed onto the workpieces by a nozzle. The cutting gas also flows through this nozzle. Depending on the application, oxygen, nitrogen or compressed air are used as the cutting gas.Middle Power Cutting,3m Round Pipe Cutting,1500W Laser Cutting,pallet fiber laser,pallet shuttle
Nitrogen cutting features:
The main advantages of nitrogen cutting is high cutting quality, widely used in cutting processing, but its disadvantage is high cost.
1) Cutting quality
According to the use of auxiliary gas, laser cutting machine can be divided into oxygen, nitrogen two cutting methods. Oxygen is involved in combustion during oxygen cutting, and the melting point is close to the boiling point. High temperature lead to severe reaction, can not guarantee smooth section; the other with the oxidation reaction, increased heat affected zone, the cutting quality is relatively poor, prone to slit width, cross-section twill, surface roughness and welding slag quality defects. Nitrogen cutting material completely rely on laser energy melting, nitrogen blowing out the slit and avoid inappropriate chemical reaction. The temperature of the melting point area is relatively low, with nitrogen cooling, protection, the reaction is stable, uniform, high-quality cutting. Smooth cross-section, low surface roughness, and no oxide layer.
