ABSTRACT:
A fan jet nozzle for use with an ultra high pressure liquid-phase cleaning media for use in a deflashing apparatus includes a nozzle tip, which is made of a super hard material such as diamond, and is secured inside a nozzle holder through sintering. Upper and lower nozzle bores above and beneath the nozzle tip are processed to converge and communicate with each other inside the nozzle tip, resulting in a center nozzle hole having an elliptical shape. One of the upper and lower nozzle bores is processed into a circular cone shape, and the other one of the upper and lower nozzle bores is processed to have an arched longitudinal sectional shape and a cross sectional shape wherein its width increases toward a center thereof and decreases toward both sides thereof.
