Wire EDM Machining Process

Wire EDM machining follows a controlled, multi-stage process—from programming and setup to precision cutting and post-processing—ensuring accuracy, stability, and repeatability for hard and complex parts.

  • Drawing & Programming

    Prepare CAD drawings with machining contours, tolerances, and discharge compensation. Generate cutting paths using CAM software such as Mastercam or CAXA.

    01

  • Workpiece & Wire Selection

    Select suitable electrode wire based on material type and thickness. Pre-treat workpieces and drill wire start holes as required.

    02

  • Machine Setup & Calibration

    Fix the workpiece securely, align verticality and flatness, thread and tension the wire, and configure dielectric fluid conditions.

    03

  • EDM Cutting Process

    Perform rough cutting followed by multiple finishing passes. Slow-wire EDM enables higher accuracy and improved surface quality.

    04

  • Post-Processing & Inspection

    Remove recast layers, apply stress-relief treatment if required, and inspect dimensions and surface quality using precision measuring equipment.
