Abstract
The invention relates to a method for manufacturing hollow spaces (5) in metallic workpieces (1), especially in fuel injectors for diesel engines with at least one main bore (3) and at least one supply bore (4), especially for fuel supply, wherein at least one electrode (2) is introduced into the main bore (3) and the hollow space (5) and/or the connection to the supply bore (4) is formed by means of an electrolytic erosion process. It is the object of the invention to provide a method by which the use of an additional washing process can be eliminated. The object upon which the invention is based is solved in that the supply bore (4) is flushed at least temporarily with electrolyte.
