Abstract

The invention relates to a device for electrochemical dimensional machining and is used in electrochemical and electrophysical metal working processes. The invention can also be used for supplying an operating current during electrochemical dimensional machining. The aim of the invention is to enlarge the technological performance of the electrochemical dimensional machining process; to ensure the stability thereof; to upgrade accuracy; to increase performance in a machined area; to reduce the energy consumption for electrochemical machining; and to improve ecological safety. The result is obtained by using an battery of accumulators with gas recombination for supplying the operating current.
