Abstract

PURPOSE: To enable a hole-type nozzle to be produced efficiently and accurately which is free from notches on the edge thereof adjacent its exit and also from a warped or eliptical deformation of such edge and is improved in its emission features.
CONSTITUTION: For production of a nozzle, a stock material is worked to form a hole A for receiving a needle valve, a valve seat V, a suck hole S, a profile P and so on, whereafter a tip portion C of a nozzle N in which a nozzle hole H is to be formed is formed with a thickness or finishing allowance t additional to the final shape thereof shown in broken line. Then, a predetermined number of nozzle holes H of a predetermined diameter d are formed in the tip portion C by means of a drill D. Subsequently, the finishing allowance section t is removed in order to obtain the final shape of the nozzle N completed. According to this production method, notches, a warped deformation, and the like, of nozzle holes H caused to appear by whirling of the drill D or the like when the nozzle holes H are formed by the drill D can be removed upon and together with removal of the finishing allowance section t at the final step.
