CI 400

The EMAG CI 400 Electrochemical Machining Unit is the Perfect Solution for the Production of Rotor Carriers

Rotor carriers are components of electric motor housings for hybrid vehicles and the quantities produced are continuing to increase. Electrochemical machining, or ECM, provides major benefits for the production of these parts.

Designed for the Production of Machining Pipe Carriers

Easier: Burr- and chip-free machining for high output quantities

Stability: Thermally neutral machining while simultaneously avoiding microscopic cracks and white layers

Faster: Machining several workpieces simultaneously with several active cathodes

Flexibility: The CI 400 is flexible enough to enable both soft and hard machining

What is ECM?

Electrochemical machining is a contact-free production process that chemically removes material from a component, and is particularly effective when working with hard materials. This process is perfect for everything from simple deburring all the way to manufacturing.

The ECM technology provides residue-free machining of metal parts without contacting the workpiece. This makes the technology ideal for machining thin-walled workpieces, such as rotor carriers. Since the tool never makes contact with the workpiece at any time during machining, there is absolutely no warping. ECM also creates surfaces that require no finishing after the process.
