Manufacture of high-precision surfaces efficiently with the minimum time of finish of the workpiece is a primary objective of production engineers working in areas such as aerospace, transport and energy. The components that have complex shapes with very low finish tolerances are often required. The effects of component stress as a result of the manufacturing process are also a concern for the components which should be functional under extreme conditions of operation.

The machining process Extrude Hone ECM provides solutions that you will provide the results you need, when the accuracy, consistency, time and quality are fundamental.

Electrochemical machining is a method that has just the surface of the workpiece by means of Anodic dissolution of metal. The machining tool is the cathode (-) It operates with a CC current and the presence of an electrolyte fluid to create the Anodic reaction that removes material from the surface of the workpiece (+) one way needs.

As the ECM process works:

• Electrolyte solution transfers carry the gap between the cathode and the workpiece, what causes the transfer of electrons from the workpiece to remove surface material.
• The distance of separation between the cathode and the workpiece is the key to the process of material removal.
• The cathode form determines the final shape of the workpiece or printing (imaging) placed on the workpiece.
• The rate of material removal is dictated by the CC current applied.
• The amount of material removed is set by Faraday's Laws.
• The material removed during the process should be filtered out of the chain of electrolyte, in order to maintain the quality of the electrolyte at the interval between the cathode and the workpiece.
