Nukon NK Nozzles Chromed

Product Overview

These nozzles feature a hard chromium plating layer applied to high-grade brass or steel substrates, creating a wear-resistant surface that withstands abrasive gases and metal splatters. Available in various orifice sizes (typically 2.5mm–4mm), they optimize gas flow dynamics—whether using nitrogen, oxygen, or compressed air—to ensure clean, burr-free cuts in metal processing. Designed for compatibility with Nukon laser cutting heads, these nozzles reduce downtime by extending maintenance intervals and improving overall process stability .

Product Features

Chromed Surface Durability: The chromium plating provides a hardness of 65–70 HRC, resisting corrosion and wear from high-velocity gas flow and molten metal contact, extending service life by up to 30% compared to uncoated nozzles.

Precision Orifice Design: Each nozzle’s orifice is machined to tight tolerances (±0.02mm), ensuring consistent gas pressure distribution and a stable laser-material interaction zone .

Optimized Gas Flow: The internal geometry minimizes turbulence, delivering a focused gas jet that removes molten material efficiently, reducing dross formation in carbon steel and stainless steel cutting.

Easy Installation: Standardized threading and dimensions ensure quick replacement, minimizing machine downtime during maintenance.

Product Applications

These nozzles excel in various laser cutting scenarios:

Carbon Steel Cutting: Using oxygen as an assist gas to achieve fast, clean cuts in 3–12mm thick sheets.

Stainless Steel Processing: Compatible with nitrogen gas to prevent oxidation, ideal for food-grade or decorative stainless steel components.

Aluminum Alloys: Optimized gas flow reduces reflection-induced nozzle damage when cutting aluminum up to 6mm thick.

High-Volume Production: Their durability makes them suitable for 24/7 manufacturing environments, such as automotive part production lines.

FAQ

Q: What orifice size should I choose for my application?

A: Smaller orifices (2.5mm) work best for thin materials (<3mm) and precision cuts, while larger sizes (4mm) are better for thick materials (>8mm) requiring higher gas flow .

Q: How often should the nozzles be cleaned or replaced?

A: Clean daily to remove debris; replace every 40–80 hours of operation, depending on material type. Cutting abrasive materials may require more frequent replacement .

Q: Can they be used with all assist gases?

A: Yes, they are compatible with oxygen, nitrogen, and compressed air. However, avoid using corrosive gases (e.g., chlorine) as they may damage the chrome plating.

Q: Are they compatible with non-Nukon laser heads?

A: They fit most standard laser heads with matching thread sizes (e.g., M12, M16). Check your machine’s nozzle specifications for compatibility.
