FIELD: process engineering.
SUBSTANCE: invention relates to electrophysical and electrochemical processing of bores and may be used in combined electroerosion-chemical machining of cooling bores in turbine bores. Proposed method comprises feeding cathode tool along axis for electrolyte to be fed there through. Note here that tubular cathode tool is revolved and axially fed an variable rate.
EFFECT: higher quality of machining, expanded process performances.
