FIELD: electrochemical treatment of channel edges.
SUBSTANCE: proposed method includes anode dissolving of burrs on edges of cast part channel by means of electrode-tool performing the reciprocating motion along its axis; after reaching burrs, amplitude of oscillations is reduced till complete removal of burrs. Device proposed for realization of this method includes electrode-tool with body, working part and dielectric guide. Electrode-tool has through channel with check valve between end face of dielectric guide and body. Electrode-tool is connected with reciprocating motion drive and motion direction sensor. Length of working part of electrode-tool shall be no less than maximum length of burrs to reduce the electrode gap and to minimize zone of treatment.
EFFECT: enhanced efficiency.
