Laser cutting machine nozzle height refers to the distance between the nozzle outlet and the workpiece surface. The role of the nozzle is that the auxiliary gas is rapidly emitted, which can effectively prevent the debris such as melting from bouncing up, and then protect the focusing mirror; The high pressure gas can blow away the slag produced by cutting and improve the cutting efficiency.

What will happen if the nozzle height of the laser cutting machine is not suitable?

The nozzle of the laser cutting machine is too low, and the nozzle is easy to collide with the workpiece surface; Too high will reduce the concentration and pressure of the auxiliary gas, resulting in a reduction in cutting quality.

Laser cutting machine plate thickness and nozzle aperture selection?

Cut the thin plate below 3mm, choose a nozzle with a diameter of 1.5mm aperture, the corner will be easier to contain stains; Choose a nozzle with a diameter of 1mm aperture will be thinner and the cutting effect is better.

When cutting a thick plate of more than 3mm, the nozzle with a diameter of Φ1.5mm is selected for large gas diffusion area and slow gas flow rate, so it is relatively stable when cutting. If the nozzle with a diameter of 1mm is used, the gas diffusion area is small, so it is not stable, because the cutting power is high, the relative heat dissipation time is longer, and the nozzle with a diameter of 1mm is not stable when used. The relative cutting time has also increased, but it is still basically usable.

When cutting plates more than 10mm, the nozzle with a diameter of 2mm or more is generally selected.

Laser cutting machine nozzle use precautions?

1. The melting stains on the nozzle should be cleaned up in time so as not to affect the cutting quality.

2. The nozzle should be carefully placed, should not be damaged, so as to avoid deformation.

3. The nozzle should be accurate when manufacturing, and need to be installed correctly.

4. If the conditions are changed during the cutting process due to the poor quality of the nozzle, the nozzle should be replaced in time.
