Fiber Laser ceramic ring is mounted on the laser cutting head above the nozzle, under the sensor. Fiber laser ceramic is responsible for transmitting and collecting the cutting signal emitted by the nozzle, in order to prevent the nozzle from colliding with the plate during operation, which will damage the cutting head.

The fiber laser nozzle is one of the most important parts of the fiber laser cutting machine.Its installed at the bottom of the laser head, the laser power and high-pressure airflow is emitted through the nozzle, which is related to the cutting quality and service life of laser cutting equipment. What are some tips we will give you to choose a suitable nozzle for your machine?

How laser nozzles affect cutting performance

1.Through the inner shape of the laser head nozzle, the airflow direction and the air pressure of the high-pressure airflow are to maintain the pressure between the workpiece and the Fiber Laser raytool nozzle.

2.The inner lens of the laser head is protected to prevent workpiece melt from splashing back into the laser head.

3.The capacitor signal is for the height adjustment system to ensure the stable operation of the height adjustment system.

Types of nozzles are:

They divide common laser cutting nozzles into single and double layers.

Single-layer nozzles are used for melting and cutting, they use nitrogen as an auxiliary gas, and are commonly used for cutting stainless steel, aluminum alloys, brass, etc.

The double-layer nozzle is usually used for oxidative cutting,where oxygen is used as the auxiliary gas, which is generally used for cutting carbon steel.

How to choose the caliber of the nozzle?

The laser cutting machine nozzle helps in expelling the gas faster as it prevents the molten stains from bouncing off effectively thus protecting the focusing mirror. Also, it controls the gas diffusion area and size, which affects the quality of the laser cutting machine.

For fiber laser ospri/WSX nozzle this reason the aperture size of the nozzle varies with the thickness of the material to be cut.

First, sheet cutting (below 3mm)

A nozzle with a 1mm aperture will be fine, while a nozzle with a 1.5mm aperture will be thicker, and easier to get stained in the corner.

Second, cutting thick plate (above 3mm)

A nozzle with a 1 mm aperture does not freeze when in use.

Because the cutting force is high, the relative heat dissipation time is long, and the relative cutting time increases, the gas diffusion area of ​​the nozzle with a 1mm aperture is small, so it is not stable, but its basic form can be used from.

The Laser nozzle with a 1.5 mm aperture has a larger gas diffusion area and a slower gas velocity, so it is more stable when cutting.

Third, cutting plates above 10mm. 

At present, nozzles with a diameter above 2mm or 2mm are usually selected.

However, the bigger the aperture of the nozzle, the less the protective effect on the focusing mirror.

Therefore,the Laser cutting nozzle proper selection of the aperture size of the nozzle of the laser cutting machine can carry out the product more effectively.
