ELECTROCHEMICAL DEBURRING (ECM) Extrude Hone

ELECTROCHEMICAL DEBURRING (ECM) Electrochemical deburring is a method that finishes the workpiece surfaces by means of anodic metal dissolution. The deburring tool is the cathode (-) that acts under DC current and in the presence of an electrolyte fluid to create the anodic reaction that removes workpiece (+) surface material in a precise manner.
