EDM Electrode Machining

Precision EDM Electrode Machining

Specialized CNC machining for the production of high-precision EDM electrodes. We process copper, graphite, and composite materials to create complex electrode geometries that will form the intricate details of your mold cavities and cores.

Electrode Materials & Geometry

Expertise in machining red copper, tungsten copper, and fine-grain graphite. Our CNC centers deliver the dimensional accuracy required for deep ribs, thin walls, and complex 3D surfaces, ensuring the electrode replicates perfectly during the EDM sparking process.

Tight Tolerances for EDM

Electrodes are machined to ultra-tight tolerances to compensate for spark gap and electrode wear. This precision ensures that the final molded part meets the exact specifications and surface finish requirements without extensive post-polishing.

Electrode Inspection & Verification

Each electrode undergoes rigorous inspection using CMM and optical measuring equipment. We verify the geometry, surface finish, and reference datums before the part moves to the EDM department, minimizing errors and ensuring a perfect burn.

Seamless Integration

Our electrode machining process is fully integrated with our EDM sinking services. This streamlined workflow ensures quick turnaround times and complete traceability from the raw electrode material to the finished mold component.
