Abstract
The invention relates to a process and an apparatus for the electrochemical etching of grooves of very small width, in particular smaller than 1.0 mm, into a workpiece. Etching is performed with a wire electrode or a rod electrode extending across the etching direction. In order that the electrolyte liquid introduced into the work gap does not flow away uncontrolled, but fills out the work gap over the entire working length of the electrode, a baffle acting behind the rear of the electrode is provided. This ensures that the flow of the electrolyte takes place essentially in the work gap and in the longitudinal direction.
