Beschreibung
Zusammenfassung:	FIELD: manufacture of precision complex-shape machine parts and shaping tools of high-strength steels and alloys. SUBSTANCE: working member of tool-electrode is made of metallic foil in the form of membrane secured to holder in center and along circular periphery. Said membrane has central opening and shaping members around it. Holder has openings for supplying electrolyte to working zone and annular duct. Lateral surface of said duct is coated with insulation material. In central portion of holder above mentioned duct forms abutment for pressure screw designed for securing circular membrane. The last is arranged in such a way that it closes annular duct by means of shaping members and it is secured to end flat surface of holder normally relative to its axis. Openings for supplying electrolyte to working zone are inclined relative to holder axis and they are communicated with annular duct. EFFECT: uniform hydrodynamic condition along the whole worked surface, enhanced accuracy of working. 2 dwg
