METHOD OF GENERATING CURRENT PULSES IN ELECTROCHEMICAL WORKING

摘要

FIELD: process engineering.;SUBSTANCE: invention relates to machine building and may be used in spark erosion machining, electrochemical machining and combined erosion-chemical machining. Proposed method comprises placing processed part and electrode-tool made from high-temperature superconductivity ceramic oxide in liquid nitrogen, cooling them down unless superconductivity development, feeding constant current to said electrode-tool and machined part to adjust pulse repetition rate by current regulator.;EFFECT: reduced duration of machining.;2 dwg, 1 ex
