  • Method for a removal of cathode depositions by means of bipolar pulses
    Patent number: 6620307
    Abstract: A method for on-line removal of cathode depositions during electrochemical process. The process control unit (30) is arranged to alternate the unipolar machining voltage pulses U1 with the voltage pulses of opposite polarity U2 to the work piece (2) and the cathode (3). The process control unit comprises an arrangement to determine the amount of cathode depositions on-line based on the operational parameter. Only in case the operational parameter exceeds the allowable level, the process control unit (30) alternates the unipolar machining voltage pulses U1 with the voltage pulses of opposite polarity U2. In this case the cathode wear is minimized.
