What Is CNC EDM Machining?
Usinagem 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. Ao contrário da usinagem 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.
Na sua essência, Usinagem de descarga elétrica works by creating a series of tiny sparks (each lasting just microseconds) in a dielectric fluid (Por exemplo, 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. Tecnologia 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.

Processo: The CNC EDM Machining Steps
O CNC EDM Process follows a structured sequence of steps to ensure accuracy, eficiência, e consistência. Below is a step-by-step overview of our Processo de usinagem:
- Projeto & Programação: Primeiro, we convert your 3D CAD model (Por exemplo, Stl, ETAPA) into a CNC program. This program defines the electrode’s path, spark parameters (Por exemplo, tensão, atual), 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 peças complexas, multiple electrodes may be used for roughing (fast material removal) e acabamento (precision shaping).
- Configuração da peça de trabalho: 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.
- Execução de usinagem: 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.
Inspeção de qualidade: Após a usinagem, the part is cleaned and inspected using tools like coordinate measuring machines (Cmms) to verify dimensions and tolerances.
