METHOD OF ELECTROCHEMICAL PROCESSING TO SIZES (VERSIONS) Russian patent published in 2011 - IPC B23H3/00 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming and may be used in electrochemical processing to sizes. Proposed method comprises setting one of electrodes translating and feeding operating voltage pulses thereto, synchronizing pulse feed start with electrodes rendezvous phase, and checking electrolyte flow rate and pulse voltage. In compliance with first version, operating voltage pulses fed represents square unipolar pulses or half-wave unipolar sine pulses with pulse repetition rate of 0.2 kHz to 20 kHz and on-off time ratio of 2. In compliance with second version, operating voltage pulses are produced by superimposing voltage sine 0.5-15 kHz-constant-frequency oscillations on constant voltage. Note here that ratio between AC voltage amplitude and DC voltage is kept constant in the range of 0.1-0.9.

EFFECT: higher accuracy and simplified process.
