FIELD: process engineering.
SUBSTANCE: invention relates o metal processing using mechanical and electrochemical processing of hard metal, for example, tungsten, cast iron etc. Proposed electrode-tool comprises set of aligned disks arranged off-center. Besides, electrode-tool incorporates extra disk arranged relative to rotational axis of electrode-tool without eccentricity and between said disks for permanent contact therewith.
EFFECT: higher quality of machined surface.
