AIRLESS SPRAY NOZZLE AND METHOD OF MANUFACTURE Abstract of the Disclosure An airless spray nozzle comprising a nozzle adapter and a hard, abrasive resistant nozzle tip. The nozzle tip is sealingly brazed within an axial passage of the adapter and is mechanically locked against hydraulic pressure ejection from the adapter by lips formed on the adapter and swaged over the tip. The nozzle adapter is manufactured by a series of machining steps which includes trepanning a recess into the front face of the adapter and then subsequently straddle milling the front face to simultaneously form protective ears on the front face of the nozzle and the lips for mechanically locking the tip into the adapter. After assembly of the nozzle and tip, an outlet orifice is machined into the tip by passing a cutter grinder wheel between the spaced ears and the spaced lips on the front face of the adapter.
