Raytools Laser Cutting Nozzles

The nozzle is the final component in the cutting process path: it precisely directs the cutting gas (oxygen, nitrogen or compressed air), which cools the cutting zone, removes molten material and supports process stability during piercing. Nozzle selection influences edge quality and colour, the amount of dross, kerf width and the sensitivity of the process to variations in height and cutting speed. A nozzle diameter that is too small restricts gas flow and increases the risk of burning; an excessively large diameter reduces gas jet concentration and may increase kerf taper. The geometry of the nozzle face and the nozzle-to-material distance are equally important — maintaining the correct stand-off distance stabilises the height sensing system and helps ensure repeatable cutting along the entire workpiece.

When selecting a nozzle, check compatibility with the model of the Raytools laser head as well as the type and thickness of the material being processed. Carbon steel cut with oxygen generally requires a somewhat different nozzle diameter from stainless steel or aluminium cut with nitrogen or compressed air; smaller diameters are suitable for thin sheet where a more precise edge is required, while thicker material typically requires a larger diameter to provide sufficient gas flow and effective removal of molten material. Nozzle manufacturing quality is equally important: smooth, clean orifice edges and consistent nickel plating or brass construction help provide a stable, axial gas jet and reduce the risk of blockage.
