ECM

Historically, the power of a car’s engine was dependent on the number and size of cylinders – today, that’s a thing of the past! Electronic engine control, turbochargers or compressors are responsible for the overall performance. The turbocharger has a particularly important role—a Swiss invention dating back to 1925, the turbocharger was used to considerably increase engine power. What distinguishes this component, why is it increasingly important and what are the benefits of using electrochemical machining? —Five interesting facts about turbochargers:

Electro-chemical machining (ECM) is a fascinating production method, because the technology involves virtually no workpiece contact: A direct current, or pulse, is used to polarize the workpiece positively, to create an anode, and the tool negatively, for the cathode. An electrolyte solution flows between the two, and metal ions detach from the workpiece. The components are not exposed to any mechanical or thermal stress during the process.
