ABSTRACT:
A method for producing a hole in a body, especially an injection hole in a fuel injector is disclosed. The hole (L) is first produced by a percussion boring process or a trepanation boring process using a laser. The percussion boring process lasts less than 3 seconds. The trepanation boring process lasts less than 10 seconds. After percussion boring or trepanation boring a smoothing step is carried out by forcing a medium that is mixed with abrasive particles under pressure through the hole until any roughnesses of surfaces (F) of the body that form the hole (L) are substantially removed.
