ZNK D28 H22.5 M11 Fiber Laser Cutting Nozzle
The ZNK D28 H22.5 M11 laser cutting nozzle is a precision consumable for fiber laser cutting heads. It shapes and directs the assist-gas flow around the focused beam, protecting the focus lens from spatter and helping produce clean, stable cut edges. The dimensions are fixed by the model designation for a straightforward, repeatable fit.
