Electrochemical Machining (ECM)

概述

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.

日常示例

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

工业重要性

电化学加工被广泛用于航空发动机叶片、汽车发动机缸体及医疗器械的精密制造，其优势在于无切削力、无热变形、表面质量高。
