Correct selection and use of fiber laser cutting machine nozzle is very important

The selection and use of fiber laser cutting machine nozzles are very important, and it is directly related to the cutting effect, so how do we choose?

First of all, when cutting thin plates below 3mm, it is recommended to choose a Φ1mm aperture nozzle. The cutting is relatively fine. When a Φ1.5mm aperture nozzle is selected, the cutting will be thicker, and the corner cutting is prone to stains.

Secondly, when cutting the middle plate of 3-10mm, when choosing the Φ1mm aperture nozzle, the laser power is higher, the cutting is unstable, the gas diffusion area is small, and the heat dissipation time is long, resulting in a longer cutting time, but it can still be used; choose Φ1. The nozzle with a 5mm aperture has a large gas diffusion area and a slow gas flow rate, so it is relatively stable during cutting and can have a better cutting effect.

Finally, when cutting thick plates of 10mm or more, nozzles with diameters of 2mm and above are generally selected. The larger the nozzle diameter, the smaller the protection of the focusing lens. A reasonable choice of the nozzle hole size of the laser cutting machine can effectively perform laser cutting of the plate and improve Productivity.

In general, the correct selection of the nozzle aperture size of the laser cutting machine is very important. The operation engineer should change the nozzle aperture size in real time according to the thickness of the cutting material, and the nozzle must be carefully selected before use.
