EDM, or Electrical Discharge Machining, is a highly specialized manufacturing process used for precision machining of conductive materials. This process uses electrical discharges, or sparks, to erode material from the workpiece. EDM is particularly effective for hard materials that are challenging to machine using traditional methods, making it invaluable for creating intricate molds, dies, and complex components.

The process involves an electrode and the workpiece submerged in a dielectric fluid. The electrode delivers controlled electrical discharges to the workpiece, eroding it into the desired shape with high precision. EDM is known for its ability to produce extremely fine details and complex shapes with smooth surfaces, often eliminating the need for additional finishing.

Wire-Cut EDM

Wire-Cut EDM is a variation of Electrical Discharge Machining that uses a continuously moving thin wire as an electrode. This method is renowned for its exceptional precision and ability to produce intricate and delicate shapes in conductive materials. Wire-Cut EDM is ideal for manufacturing complex parts with tight tolerances and fine features.

In Wire-Cut EDM, the wire electrode, typically made of brass or stratified copper, moves through the workpiece and cuts the material in a controlled manner. This process is especially useful for creating complex 2D shapes, narrow slots, and sharp inside corners with a high degree of accuracy. The wire’s path is controlled by a CNC system, ensuring precision and repeatability in the cutting process.
