28mm Double Style Laser Nozzle

The laser nozzle is vital in laser cutting, managing distance, directing gas flow, creating high pressure for faster cutting, removing slag, and protecting lenses. It impacts cutting quality directly.

Types of nozzles include:

Single-layer: Uses nitrogen for melting cutting of stainless steel and aluminum alloy.

Double-layer: Uses oxygen for oxidative cutting of carbon steel.

Aperture size affects cutting quality:

Small aperture: Best for thin plates, finer surface but may leave slag at corners.

Large aperture: Suitable for thick plates, stable cutting but less lens protection, risking damage from sparks.

Coaxiality between the nozzle outlet and laser beam is critical, especially for thick workpieces, ensuring better cutting results.
