Gas and pressure for fiber laser cutting machine

Gas and pressure for fiber laser cutting machine.

When the fiber laser cutting machine running, need different cutting gases according to the material.

The choice of gas and pressure has a great impact on the quality of fiber laser cutting machines.

Effect on cutting quality:

Firstly.The cutting gas helps to dissipate heat and assist combustion, and blows off the melt to obtain a better quality cut section.

Secondly.When the pressure of the cutting gas is insufficient,the melting will occur during cutting. And the cutting speed cannot meet the production efficiency.

Thirdly.When the pressure of the cutting gas is too high, the cutting surface is rough, and the slit is wide. At the same time,can not make a good cutting section.

The effect of cutting gas pressure:

Firstly. When the gas pressure is too low, the laser does not easily penetrate the cut sheet,resulting in low productivity.

Secondly.When the gas pressure is too high, the penetration point is to form a large melting point, which affects the quality of the cutting.

Thirdly.When laser drilling, generally, a higher gas pressure is for the thin plate member, and a specific punching method is for the thick plate member, thereby eliminating the disadvantage of the low air pressure to protect the lens.

Finally.When the laser cutting machine cuts ordinary carbon steel, the thicker the material, the lower the pressure of the cutting gas. When cutting stainless steel, the cutting gas pressure increases relatively with the thickness of the material. In short, the choice of cutting gas and pressure during laser cutting must be adjusted according to the actual situation during cutting. In specific applications, different cutting parameters should be selected according to the specific conditions.
