Electrochemical Machining (ECM)

Fe → Fe2+ + 2e

Descripción general

Electrochemical machining dissolves metal from a workpiece (anode) in a controlled pattern using a shaped cathode tool and flowing electrolyte (typically NaCl or NaNO₃ solution). Material removal rates of 0.5–15 mm³/s are achieved without tool wear, heat-affected zones, or mechanical stress. The process mirrors the shape of the tool electrode.

Ejemplo cotidiano

Turbine blades for jet engines are precision-shaped by ECM to achieve complex airfoil profiles impossible to machine conventionally.

Importancia industrial

El mecanizado electroquímico se aplica en aeroespacial, implantes médicos y fabricación de matrices y moldes para mecanizar aleaciones duras y geometrías complejas.
