Wire EDM Technology Overview: A Comprehensive Guide

Wire electrical discharge machining (wire EDM), also known as wire-cut EDM, is a precise, non-traditional machining process that utilises a thin wire electrode to erode hard, conductive materials. Unlike conventional machining methods that rely on mechanical forces, wire EDM employs a series of electrical sparks to remove material from the workpiece. This unique approach enables Wire EDM Technology to produce complex geometries, tight corners, and small internal features with exceptional accuracy and surface finish.
