How Do I Choose a Fiber Laser Nozzle in a Cutting Machine?

Fiber Laser Spares is the best company in India. Fiber laser parts have very good quality nozzles. The fiber laser nozzle of the laser cutting machine helps to expel the gas rapidly, which effectively prevents other debris from moving upward, which can damage the focusing lens. The nozzle protects the through and it controls the area and size of the gas diffusion, which affects the cutting quality of the laser cutting machine.

 

1. Types of Nozzles

The common laser cutting nozzles we supply are divided into single and double layers. They use single layer nozzles for melting and cutting, i.e. nitrogen is used as auxiliary gas, and they are commonly used for cutting stainless steel, aluminum alloy, brass etc. Double-layer nozzles are used for oxidative cutting and they use oxygen as an auxiliary the gas, which is commonly used to cut carbon steel.

 

2. Nozzle Size Selection

The diameter of the nozzle determines the size of the gas flow in the incision, the gas diffusion area and the gas flow rate, which greatly affects the melt removal and cutting stability.

 

The stronger the melt removal ability of the spray, the more laser power is used and the fiber laser raytool nozzle is sized according to the thickness of the metal sheet.

In principle, the thicker the plate, the greater the use of the nozzle, the higher the setting pressure of the proportional valve, the lower the flow rate, and the pressure is the normal section effect.

 

3. Choice of different power nozzles

 

(1) laser power≤6000w

Carbon steel cutting, laser nozzle diameter is generally double layer S1.0-5.0E;

The use of a WPCT single layer nozzle simplifies the specifications of cutting stainless steel.

 

(2) laser power 6000w

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

The use of a WPCT single layer nozzle simplifies the specifications of cutting stainless steel.
