Electrochemical Machining



Electrochemical Machining - Process

Based on Faraday's law, the removal of metal by electrolysis is actually an anodic dissolution.
The workpiece or deburring is connected to the positive pole (+) of a current generator.
An electrode, the tool is placed in front of the area to be treated. It is connected to the negative pole (-) of the current generator.
The gap, area left free between the pair part / tool is filled with a conductive liquid electrolyte. It is composed of water containing sodium nitrate (NaNO3) or sodium chloride (NaCl).
The removed material is converted to metal hydroxides, removed by filtration.
It therefore applies to all types of metal parts, for machining or deburring operations, for production of small, medium and large series.
Advantages :
  • Selective machining and deburring : the tool is designed to deburr  the required area only;
  • Reproducible machining and deburring : according to the Faraday's law, the amount of material removed is proportional to the current consumed during the cycle time;
  • Machining and deburring without  any mechanical or thermic stress on the workpiece;
  • Reduced machining  time;
  • Polishing of the machined or deburred areas;
  • Removal of incipient cracks;
  • No tool wear due to process.
