FIELD: electrochemical finishing of injectors of liquid-propellant rocket engines manufactured from current- conducting materials. SUBSTANCE: enhanced efficiency of technological process of manufacture of injectors and reduced cost of their production are achieved first of all by feed of current-conducting liquid without conveying current to tool-cathode, by recording of its flow rate through each machined hole, by detection of hole with maximum flow rate and by plugging holes. After it current is fed and holes located behind hole with maximum flow rate are opened in sequence and current-conducting liquid is pumped through each hole till flow rate equal to flow rate through hole with maximum flow rate is achieved in each hole. EFFECT: enhanced efficiency of technological process and reduced cost of production of injectors. 1 dwg
