Electrochemical Machining (ECM)

Fe → Fe²⁺ + 2e⁻

Aperçu

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.
