ABSTRACT:
A nozzle for a cutting torch has three coaxial parts. An inner nozzle part includes an axial cutting duct, and machined longitudinal ducts for a fuel-gas/oxygen mixture which are open on the outside. The inner nozzle part is inserted into an outer nozzle part which radially delimits the longitudinal ducts. An annular mixer part is on a head region of the nozzle, radially delimiting the longitudinal ducts at the attachment to the outer nozzle part. The mixer part has radial bores which open as fuel gas passages into the longitudinal ducts which supply heating oxygen. The longitudinal ducts are through-machined from the mouth of the fuel gas passages to tapered regions of the inner and outer nozzle parts.
