ABSTRACT:
An airless spray coating nozzle is made by cutting interpenetrating grooves into opposite sides of a nozzle tip blank. The groove on the pressurized or entrance side of the tip has a bottom portion which is wedge-shaped in cross section. The groove on the unpressurized or exit side of the tip has a bottom portion which is trapezoidal in cross section. Both grooves are cut into the nozzle tip with a grinding wheel after the tip has been hardened.
