PCT No. PCT/EP95/04020 Sec. 371 Date Jun. 30, 1997 Sec. 102(e) Date Jun. 30, 1997 PCT Filed Oct. 12, 1995 PCT Pub. No. WO96/12586 PCT Pub. Date May 2, 1996A process for electrochemical treating flow channels of metal workpieces uses a tool extending into the workpieces and an electrolyte flow between the tool and the flow channel. Either volume flow of the electrolyte, or pressure of the electrolyte, or both, are measured in a reference sample workpiece calibrated previously with test oil under high pressure and the determined electrolyte value is stored as a nominal value and used for a subsequent series treatment of the workpieces. This value is used as a regulating variable for termination of the treatment. The pressure of the electrolyte during the electrochemical series treatment of the workpieces is maintained at about 100 bars.
