What is Wire EDM?
Wire EDM is a non-conventional machining technique that employs a thin, electrically conductive wire to cut through materials using electrical discharges. The process is highly effective for creating complex geometries and features, making it ideal for industries such as aerospace, medical, and automotive. The wire is submerged in a dielectric fluid, which helps to control the electrical discharges and cool the workpiece.
How Wire EDM Works
The wire EDM process involves several steps:
- Setup: The workpiece is mounted on a table, and the wire is threaded through it.
- Dielectric Fluid: The workpiece and wire are submerged in a dielectric fluid, typically deionized water.
- Electrical Discharge: A series of rapid electrical pulses create sparks that erode the material from the workpiece.
- Continuous Wire Feed: As material is removed, the wire continuously feeds through the workpiece, allowing for uninterrupted cutting.
This process results in exceptionally clean cuts with tight tolerances, making wire EDM a preferred choice for precision machining.
