What Is CNC EDM Machining?
Mecanizado CNC EDM (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. A diferencia del mecanizado tradicional (which relies on physical cutting tools), EDM removes material through thermal erosion—making it ideal for hard, frágil, or complex materials that are difficult to machine with conventional methods.
En su núcleo, Mecanizado de descarga eléctrica works by creating a series of tiny sparks (each lasting just microseconds) in a dielectric fluid (P.EJ., 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. Tecnología CNC 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.

Proceso: The CNC EDM Machining Steps
El CNC EDM Process follows a structured sequence of steps to ensure accuracy, eficiencia, y consistencia. Below is a step-by-step overview of our Proceso de mecanizado:
- Diseño & Programación: Primero, we convert your 3D CAD model (P.EJ., Stl, PASO) into a CNC program. This program defines the electrode’s path, spark parameters (P.EJ., Voltaje, actual), and dielectric fluid settings—tailored to your part’s material and design.
- Electrode Preparation: We fabricate the electrode (from graphite or copper) to match the inverse shape of your desired part. Para piezas complejas, multiple electrodes may be used for roughing (fast material removal) y acabado (precision shaping).
- Configuración de la pieza de trabajo: 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.
- Ejecución de mecanizado: 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.
Inspección de calidad: Después de mecanizado, the part is cleaned and inspected using tools like coordinate measuring machines (CMMS) to verify dimensions and tolerances.
