Abstract

The tool electrode for spark-erosive machining of workpieces, in particular, for spark-erosive sinking, includes a main body (8) which is movable towards the work-piece. The main body has a coating (10) of an electrically conductive material. The installation for spark-erosive machining in a working medium has a feed unit and a sinking electrode fixed to a holder. It is characterised by the fact that there is at least one further electrode, and that workpieces are adjustable against the electrodes by means of the feed unit. Also claimed are an apparatus and method for producing tool electrodes.
