Zusammenfassung:A double nozzle for a laser processing head includes an inner body portion having an interior surface defining a bore for passing a laser beam, a first interface surface near a distal end of the inner body portion, the first interface surface including a plurality of channels, and an exterior surface near a proximal end of the inner body portion and shaped to engage the laser processing head. Each channel includes interior and exterior linear edges in a cross-section that passes though a central longitudinal axis of the double nozzle. The double nozzle also includes an outer body portion connected to the inner body portion. The outer body portion defines a jet surface, which together with the plurality of channels defines a corresponding plurality of auxiliary fluid flow paths about the bore and between the inner body portion and the outer body portion.
