The selection and use of the nozzle of the optical fiber laser cutting machine is very important, which is directly related to the cutting effect, so how should we choose?
First, it is recommended to select Φ Nozzle with 1mm aperture, fine cutting, selection Φ When the nozzle with 1.5mm aperture is cut, it will be rough, and the corner cutting area is easy to be stained.
Secondly, when cutting the middle plate 3-10mm, select Φ When using a nozzle with an aperture of 1mm, the laser power is high, 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; Instead, choose Φ The nozzle with 1.5mm aperture has a large gas diffusion area and a slow gas flow rate, so it is relatively stable during cutting and has a good cutting effect.
Finally, when cutting thick plates with a diameter of more than 10 mm, nozzles with a diameter of 2 mm or more are generally selected. The larger the nozzle diameter is, the smaller the protection effect on the focusing mirror is. A reasonable selection of the size of the nozzle diameter of the laser cutting machine can effectively perform laser cutting of plates and improve production efficiency.
In general, it is very important to correctly select the nozzle aperture size of the laser cutting machine. The operating engineer should change the nozzle aperture size in real time according to the thickness of the cutting material. The nozzle must be carefully selected before use.
