A method of electrochemical processing comprises the steps as follows: maintaining a variable gap between a processing electrode and a work-piece, having a value equal to a minimum permissible gap corresponding to processing conditions; with the gap value reaching a critical value, moving the processing electrode to obtain a gap approximately equal to or less than the critical value; applying a train of voltage pulses; and changing the length of each pulse and/or the space interval between pulses. When the space interval becomes equal to a value commensurate with the time of withdrawal of the processing electorode, a single voltage pulse is applied. An apparatus for chemical processing comprises two pickups to sense the gas content of the interelectrode space, open of said pickups being coupled to the drive means control unit, a pickup to sense the state of contact of the processing electrode and the workpiece, a processing duty decoder coupled to a program control unit to control the movement of the processing electrode. The apparatus also comprises a control signal decoder to decode control signals characteristic of the required gap, a gap value program control unit, and a control unit to control the operating duties of the voltage source.
