Abstract

See full text

The present invention relates to a method for the production of drill holes in difficult to machine materials, in which a removal of material takes place in order to produce a drill hole by electrochemical erosion of material by an electrode that is moved in the longitudinal direction of the drill hole being produced in the direction onto the material to be processed at a feed rate, wherein the drilling has at least two steps, wherein, in the first step, the electrochemical processing takes place, and wherein, in a second step, the further processing of the drill hole to the final diameter takes place by machining processing or by erosion or by an electrochemical processing.
