|ECM Developments provides a specialist electrochemical machining capability to aerospace, automotive, defence, nuclear, oil and gas, medical and other industries.
|Electrochemical Machining is a rapid, highly cost-effective machining process that eliminates heat and mechanical stress during machining. The ECM tool (cathode) is positioned close to the work piece (anode) and a low-voltage, high-amperage direct current is passed between them via an electrolyte flowing through the anode-cathode gap.
Material is removed by anodic dissolution and is carried away by the electrolyte. Two dimensional tolerances can be held to ±0.025 mm and three dimensional tolerances can be held to ±0.050 mm. Surface finishes of 0.2 to 0.4 microns can be produced in a single pass.
Electrochemical machining can be used as a metal removal or de-burring process on virtually any metal, no matter how hard or difficult to conventionally machine it is. Metal removal rates during ECM are consistent, irrespective of metal type, condition or hardness.
