D28 M11 H15 Double Layer Fiber Laser Cutting Nozzle

D28 M11 H15 Double Layer Fiber Laser Cutting Nozzle

The D28-C-15-D double layer fiber laser cutting nozzle is designed for use with compatible fiber laser cutting heads and CNC fiber laser cutting machines.

Featuring a 28 mm outer diameter, M11 threaded connection and 15 mm overall height, the nozzle provides a precise mechanical interface with the cutting head and supports controlled assist-gas delivery during the laser cutting process.

The double layer structure is suitable for fiber laser cutting applications where stable gas flow, nozzle concentricity and consistent cutting performance are important. Precision machining of the nozzle opening and internal geometry helps maintain proper gas distribution around the laser cutting zone.

This nozzle series is available in multiple aperture sizes from Ø1.0 mm to Ø4.0 mm, including the less common Ø1.25 mm specification, allowing users to select the appropriate nozzle according to laser power, sheet material, material thickness, assist gas and cutting parameters.

The D28-C-15-D can be used as a replacement fiber laser consumable for compatible cutting head configurations in industrial sheet metal processing.

Technical Specifications

Available Nozzle Aperture Sizes

Selection Note: The correct nozzle aperture should be selected according to laser power, material type, sheet thickness, assist gas, cutting head configuration and actual cutting parameters.

Typical Applications

The D28 M11 H15 double layer fiber laser nozzle is suitable for compatible laser cutting systems used in industrial sheet metal fabrication.

Typical applications include:

• Stainless steel laser cutting
• Carbon steel laser cutting
• Mild steel sheet cutting
• Galvanized steel cutting
• Aluminum sheet processing
• CNC fiber laser cutting
• Sheet metal fabrication
• Industrial metal processing
• Laser cutting machine maintenance

Depending on the laser cutting system and process requirements, different nozzle apertures may be used with oxygen, nitrogen or compressed air as the assist gas.

How to Select the Correct Laser Nozzle

Selecting the correct fiber laser nozzle requires matching both the nozzle dimensions and the actual cutting process.

Outer Diameter
Confirm that the cutting head uses a D28 / 28 mm nozzle configuration.

Thread Specification
Verify that the required nozzle connection is M11.

Overall Height
Confirm that the corresponding nozzle height is 15 mm.

Nozzle Aperture
Choose the nozzle opening according to material thickness, laser power, assist gas and cutting parameters.

Material Type
Carbon steel, stainless steel, aluminum and other materials may require different nozzle sizes and gas-flow settings.

Assist Gas
Oxygen, nitrogen and compressed air have different pressure and flow requirements.

Cutting Parameters
Laser power, focal position, cutting speed and gas pressure should be considered together when selecting the nozzle.

If the exact nozzle specification is unknown, the existing nozzle model, dimensions, markings, product photos or cutting head model can be used for identification.

Product Advantages

Stable Assist-Gas Delivery
Precision internal geometry helps support controlled gas flow during fiber laser cutting.

Accurate M11 Thread
The threaded connection is precision-machined for stable installation and convenient replacement.

Wide Aperture Selection
Multiple aperture options allow the same nozzle series to cover different sheet materials, thicknesses and cutting conditions.

Double Layer Construction
The double layer design is suitable for fiber laser cutting processes where gas-flow stability and consistent operation are important.

Reliable Dimensional Accuracy
Controlled outer diameter, height, thread and aperture dimensions help provide repeatable installation.

Suitable as a Replacement Consumable
Designed for routine replacement and maintenance of compatible fiber laser cutting heads.

Manufacturing & Quality Control

Fiber laser cutting nozzles require good dimensional accuracy because nozzle geometry can influence assist-gas flow, beam alignment and cutting stability.

Quality control focuses on:

• Nozzle aperture accuracy
• Aperture concentricity
• M11 thread accuracy
• 28 mm outer diameter consistency
• 15 mm overall height accuracy
• Internal gas passage geometry
• Surface finish
• Batch-to-batch dimensional consistency

Each nozzle specification is manufactured to support reliable installation and stable cutting performance in compatible fiber laser cutting head applications.

Ordering Information

If the exact nozzle model is unknown, customers can provide the existing nozzle markings, dimensions, cutting head model, product photos or physical sample for identification.
