ZNK D28 H22 M14 Fiber Laser Cutting Nozzle
The ZNK D28 H22 M14 laser cutting nozzle is a precision consumable for fiber laser cutting heads. It focuses the assist-gas flow around the beam and shields the focus lens from spatter, helping deliver clean and stable cut edges. The dimensions are fixed by the model designation, so the part fits directly into any head using this mounting standard.
