ECM Process
Process description:
The workpiece forms the anode, and the electrode forms the cathode of a DC current circuit.
The electrode faces the surface of the workpiece to be processed. There is a small gap between workpiece and electrode, and the electrolytic solution flows through this gap during the ECM process. The solution bridges the gap, and permits the flow of electric current, due to its conductivity. The effect of DC current and the solution causes the electro-chemical conversion of the excess material into hydroxide, which is flushed away by the solution.
The advantages of the ECM process are:
Minimum process time
Maximum quality of the finished surface, independent of skill level of personnel
Longevity of tools
Capacity to reach difficult to access burs and contours
