Zusammenfassung:	FIELD: mutually opposite finish grinding at applying electric current by means of periphery of metallic or abrasive electrically conducting grinding wheel. SUBSTANCE: electrolyte is fed to grinding zone by pulses opposite relative to wheel motion direction at side of non-worked surface of blank under pressure. Value of said pressure exceeds pressure created by mutually opposite rotation of wheel by angle providing flowing of electrolyte around wheel at side of worked surface during time period until outlet of wheel from working zone. Said time period defines pulse duration for supplying electrolyte. Pauses between electrolyte supply are controlled according to time of complete removal of electrolyte contaminated with working products during above mentioned pulse. EFFECT: enhanced accuracy of grinding due to equalizing properties of electrolyte in working zone and due to elimination of hydraulic wedge on worked surface. 1 dwg
