Knowledge of nozzles for the fiber laser cutters

We all know that nozzles is one of the important parts of the fiber laser cutters.

For the nozzles , there totally two types, single nozzle and double nozzle.

For the different equipment with different power, it need different type nozzles.

This passage will give some detailed introduction to the nozzles. hope to bring some help.

1.The different nozzles for the fiber laser cutter

First of all, the main difference for the nozzles lie as below:

The air flow of the single nozzle is concentrated, for the double nozzle, it  could bypass.

Some customers may think that the nozzle selection is related with the material thickness.

However this may misunderstanding.

The nozzle selection is concerned with the material.

For the stainless steel and some high-anti material, we equip with the single nozzle.

We know that cutting stainless steel using the Nitrogen gas.

The bigger the air flow,the quicker the cutting speed.

So for the stainless steel cutting, we equip with the single nozzle, the air flow may concentrate.

So achieving the best cutting outcome.

As for the double nozzle, we equip with it for the carbon steel cutting.

For the carbon steel, we must use the oxygen gas to cut.

Double nozzles could achieve the bypassing outcome.

There need the small air flow to cut the carbon steel to achieve the better cutting outcome.

The thicker the material, the smaller the air flow, which is different with the stainless steel cutting.

2.The different size for the nozzles about the fiber laser cutters

For the nozzles on the fiber laser cutters, there are different size of the nozzle.

There are 1.2,2.0 as well as 3.0  size for the nozzles.

The bigger of the nozzles size, the much of the volume of the gas.

For the thick material, we equip with the big size nozzle.

The nozzle is an important part of the cutting head on the fiber laser cutters.
