Electrochemical Machining (ECM)


ECM, a specialized process with many applications

Since the sixties, Köppern has been a full-service contract manufacturer for ECM-processed workpieces, from unmachined parts to finished products. We have modern ECM die-sinking machines available that can process workpieces each weighing anything from 20 g to 15,000 kg.

With its many applications, including machine and plant engineering, gas turbine or aerospace technology, ECM has become a well-established manufacturing process.

Electrochemical Machining (ECM)

Electrochemical machining has proved to be superior to other forms of processing, particularly when it comes to ‘exotic’ materials where cracks must be avoided and a high surface quality is required, as for example in the aerospace industry.

The forming of high-alloy materials, such as nickel-based or titanium alloys, or powder-metallurgical/hardened materials, is also unproblematic. The machining process produces a flash-free, high-grade surface quality without thermal stress, as the processing temperature is below 90°C.
