Typical Applications
The D28 M11 H15 double layer laser cutting nozzle is designed for compatible fiber laser cutting systems used in sheet metal processing and fabrication.
Typical applications include:
- Stainless steel laser cutting
- Carbon steel laser cutting
- Mild steel sheet cutting
- Galvanized steel cutting
- Aluminum sheet cutting
- Sheet metal fabrication
- High-speed fiber laser cutting
- CNC fiber laser cutting applications
Depending on the laser cutting system and process parameters, different nozzle apertures can be selected for cutting processes using oxygen, nitrogen or compressed air as the assist gas.
How to Select the Correct Laser Nozzle
Choosing the correct fiber laser cutting nozzle is important for maintaining stable assist-gas flow and consistent cutting performance.
The following factors should be considered when selecting the nozzle aperture:
Laser Power
Different laser power levels and cutting processes may require different nozzle aperture sizes.
Material Type
Carbon steel, stainless steel, aluminum and other materials may require different assist gases and cutting parameters.
Sheet Thickness
Thin-sheet high-speed cutting and thicker plate cutting may require different nozzle diameters and gas-flow conditions.
Assist Gas
Oxygen, nitrogen and compressed air have different pressure and flow requirements during laser cutting.
Cutting Parameters
Nozzle size should be matched with the cutting head configuration, cutting speed, focal position, gas pressure and other process parameters.
For applications where the correct nozzle specification is uncertain, the existing nozzle model, dimensions, laser cutting head model or product sample can be used for identification.
Product Advantages
Stable Assist-Gas Delivery
Precision-machined nozzle geometry supports controlled assist-gas flow around the laser cutting zone.
Accurate Dimensions
The D28 outer diameter, M11 thread and H15 overall height are precisely controlled for reliable installation in compatible cutting heads.
Multiple Aperture Options
A wide range of nozzle diameters allows one nozzle series to cover different laser powers, materials, sheet thicknesses and cutting conditions.
Suitable for High-Speed Cutting
The double layer configuration is designed for fiber laser cutting applications where stable gas flow and consistent cutting performance are required.
Convenient Maintenance
The threaded design makes nozzle inspection and replacement simple during routine laser cutting machine maintenance.
Manufacturing & Quality Control
Dimensional accuracy is particularly important for fiber laser cutting nozzles because nozzle geometry, aperture concentricity and thread accuracy can influence assist-gas distribution and cutting stability.
Quality control focuses on:
- Nozzle aperture accuracy
- Aperture concentricity
- M11 thread accuracy
- Outer dimensional consistency
- Internal gas passage geometry
- Surface finish
- Batch-to-batch dimensional consistency
Each nozzle specification is manufactured to provide reliable installation and consistent performance in compatible fiber laser cutting head applications.
