Laser Cutting Nozzle Tip Dia. 28, Height 15, M11 Fiber Laser precitec fiber laser nozzle Raytools

Description

Laser nozzle is a small part of the laser cutting machine, but it plays a very important role, the laser nozzle will have a great impact on the laser beam, the nozzle size allows only the beam through, can effectively avoid the work of possible problems. We provide variety sizes and types nozzles with large quantity in stock. Single and double layer, different apertures, for 1064nm fiber laser and also have types for Co2 laser machine.

The nozzle of the laser cutting machine can assist the rapid ejection of gas, which can effectively prevent debris and other debris from rebounding upward, thereby protecting the focusing lens and it can control the area and size of gas diffusion, which will affect the cutting of the laser cutting machine quality. How to choose the nozzle of fiber laser cutting machine?

1. Nozzle size:
Select the nozzle size according to the thickness of the metal sheet cut by the user. The aperture of the nozzle controls the gas flow and the shape of the gas field, which is very important for the cutting quality. Generally, when a laser cutting machine is applied to cut a thin plate of less than 3mm, it is recommended to use a nozzle with a diameter of 1mm, and a thickness of more than 3mm is recommend selecting a nozzle with a diameter of 1.5mm. For cutting metal plates of more than 10mm, generally select the nozzle with a diameter of 2mm or more is.

2. Nozzle material:
Good nozzle, the material must have high conductivity and good thermal conductivity. Generally, the nozzle made of copper is better than brass, which can ensure a good capacitance signal.

3. Nozzle processing accuracy:
A good laser head nozzle should have a concentric of 0.03mm, and a nozzle with a size below 1.0mm should have a concentric of 0. 02mm. High-precision concentric nozzles can not only reduce the early debugging during processing, but also effectively prevent high-energy lasers from hitting the inner wall of the laser head, thereby avoiding damage to the laser head.

4. Smoothness and anti-oxidation treatment of the nozzle surface:
The smooth surface and good anti-oxidation treatment can effectively reduce the adhesion of the melt during the cutting process and prolong the service life of the nozzle.
