Electrochemical Deburring. This method is commonly used on small metal parts with a burr in areas that cannot be reached by other deburring methods. It is basically the reverse operation to plating. Instead of adding material, electrochemical deburring eliminates it. This process uses a tool with a shape similar to the edge being deburred.
