Method for providing deep cavities in electrically conductive material, especially in automobile industry, involves mechanical processing and subsequent electrochemical processing

摘要

Manufacturing method for providing deep cavities in workpieces involves a first step in which the cavity is mechanically processed, and a second step in which the cavity is worked by electrochemical processing. A pulsed electrochemical processing procedure is used. An independent claim is included for an electrode for electrochemical processing of borings in electrically conductive material.
