The nozzle of the laser cutting machine can assist the rapid ejection of gas, and it can control the area and size of gas diffusion, which will affect the cutting quality of the laser cutting machine. When metal cutting, how to choose the nozzle of fiber laser cutting machine to get higher cutting quality?

 

1. Nozzle size selection

The user selects the nozzle size according to the thickness of the cut metal sheet.

Generally, when a laser cutting machine is apply to cut a thin plate of less than 3mm, it is recommend to use a nozzle with a diameter of 1.5mm, and a thickness of more than 3mm is recommend to select a nozzle with a diameter of 2mm. For cutting metal plates of more than 10mm, generally select the  nozzle with a diameter of 3mm or more is.

 

2. Choice of different power nozzles

(1) Laser power≤6000w

Cutting carbon steel, the nozzle diameter is generally double layer S1.0-5.0E;

Cutting stainless steel, the nozzle diameter is generally single layer S1.0-5.0E.

 

(2) Laser power ≥6000w

Cutting carbon steel, 10-25mm carbon steel bright surface cutting, the diameter of the cutting nozzle is generally double-layer high-speed E-type S1.2~1.8E; single-layer fan diameter is generally D1.2-1.8;

Cutting stainless steel, the nozzle diameter is generally single layer S1.0-5.0E.

 

When cutting different metal materials, it is very important to choose the right nozzle. I hope this post can help you better operate the fiber laser cutting machine.
