ZNK D28 Supersonic Pressurized Laser Nozzle

The D28 Supersonic Pressurized nozzle features an advanced internal channel design that accelerates assist gas to supersonic speeds, enabling faster cutting speeds and cleaner edges on thick materials. The 28mm diameter housing is compatible with major high-power cutting head systems.

Technical Specifications

Compatible Cutting Heads

• Trumpf high-power cutting heads
• Precitec HP series cutting heads
• Raytools high-power series
• Any cutting head with D28 nozzle seat for supersonic nozzle application

Application Scenarios

• High-speed carbon steel cutting (5–25mm)
• Thick stainless steel cutting (3–20mm)
• High-production-rate industrial cutting
• Shipbuilding and heavy equipment manufacturing

Installation Instructions

1. Ensure the laser machine is powered off and cutting head is cool
2. Remove the standard nozzle from the cutting head
3. Inspect the nozzle seat — ensure it is clean and undamaged
4. Install the D28 supersonic pressurized nozzle, ensuring proper thread engagement
5. Tighten firmly but avoid over-torquing to prevent thread damage
6. Set appropriate gas pressure — supersonic nozzles require higher assist gas pressure than standard nozzles (typically 10–20 bar for N2/O2)
7. Perform a test cut to fine-tune gas pressure and focus position
