FIELD: metallurgy.
SUBSTANCE: invention relates to electrochemical processing of metals and can be used for finishing of 3D complex surfaces. EDM electrode comprises body with hollow box fixed thereon in symmetry about vertical axis. Dummy of hardened non-metallic material resisting the electrolyte is secured thereon. Metal mesh-free screen to be connected to power supply negative terminal is mounted on outer surface of said dummy. Studs and adjusting screws are fitted at body bed to set clearance between said dummy and part blank. Note here that said dummy is made over the inner surface of master that makes the part blank with due allowance for clearance for electrolyte feed and screen wire diameter.
EFFECT: lower metal input in production of EDM electrode, efficient electrochemical processing.
