What Is CNC EDM Machining?

CNC EDM -Bearbeitung (Computer Numerical Control Electrical Discharge Machining) is a non-contact manufacturing process that shapes metal parts by using controlled electrical discharges (sparks) between an electrode and the workpiece. Im Gegensatz zur herkömmlichen Bearbeitung (which relies on physical cutting tools), EDM removes material through thermal erosion—making it ideal for hard, spröde, or complex materials that are difficult to machine with conventional methods.​

Im Kern, Elektrische Entladungsbearbeitung works by creating a series of tiny sparks (each lasting just microseconds) in a dielectric fluid (Z.B., deionized water or oil). These sparks generate extreme heat (up to 8,000–12,000°C), melting and vaporizing small amounts of material from the workpiece to form the desired shape. CNC -Technologie automates this process, using pre-programmed computer software to control the electrode’s movement with exceptional accuracy—ensuring consistent, repeatable results for high-volume or custom parts.

Verfahren: The CNC EDM Machining Steps

Der CNC EDM Process follows a structured sequence of steps to ensure accuracy, Effizienz, und Konsistenz. Below is a step-by-step overview of our Bearbeitungsvorgang:

  1. Design & Programmierung: Erste, we convert your 3D CAD model (Z.B., Stl, SCHRITT) into a CNC program. This program defines the electrode’s path, spark parameters (Z.B., Stromspannung, aktuell), and dielectric fluid settings—tailored to your part’s material and design.​
  1. Electrode Preparation: We fabricate the electrode (from graphite or copper) to match the inverse shape of your desired part. Für komplexe Teile, multiple electrodes may be used for roughing (schneller Materialabtrag) und fertig (precision shaping).
  1. Werkstück Setup: The workpiece is secured in a fixture on the EDM machine’s table. The dielectric fluid (deionized water for most metals) is filled into the machining tank to insulate the electrode and workpiece, and to flush away melted material.​
  1. Bearbeitungsausführung: The CNC system moves the electrode toward the workpiece until a spark gap (typically 0.01–0.1mm) is achieved. Sparks discharge between the electrode and workpiece, eroding material until the part matches the CAD design.​

Qualitätsinspektion: Nach der Bearbeitung, the part is cleaned and inspected using tools like coordinate measuring machines (Cmm) to verify dimensions and tolerances.

Vorteile: Why Choose CNC EDM Machining?

CNC EDM -Bearbeitung offers unique Vorteile that set it apart from traditional machining methods. Unten sind der Schlüssel Advantages of CNC EDM:

  • No Physical Tool Wear: Since EDM uses sparks (keine Werkzeuge schneiden) to remove material, there’s no tool degradation—ensuring consistent precision across large production runs.​
  • Ideal für komplexe Formen: EDM can machine undercuts, tiefe Hohlräume, and 3D contours that are impossible with milling or turning. This is especially valuable for mold and die manufacturing.​
  • Works with Hard Materials: It processes metals with hardness up to 65 HRC (Z.B., Werkzeugstahl, Wolfram -Carbid) without damaging the workpiece—eliminating the need for pre-softening heat treatments.​
  • Überlegene Präzision: Mit Präzisionsvorteile like ±0.001mm tolerance, EDM is ideal for micro-components and critical parts (Z.B., Medizinische Implantate).

Kostenvorteile: For small-batch or custom parts, EDM reduces tooling costs (Sie müssen keine benutzerdefinierten Schneidwerkzeuge benötigen) and shortens lead times—saving you time and money.
