As the name suggests, this casting machining method uses electrical discharges to shape metal. It is especially suitable for ultra-complex metal parts.
EDM removes material using controlled electrical sparks. This technology is widely used in casting foundries. In this method, a dielectric fluid separates the workpiece and the electrode. Sparks generally erode the metal and create the desired shape.
This method is used in casting foundries to make molds and dies. Later, casting foundries use these molds to create unique metal parts. EDM is also prevalent when making fine-tuned and finished cast parts.
Features & Benefits
- EDM casting machining can achieve extremely high tolerances. Experts said you can achieve tolerances up to ±0.0001 mm.
- You can create a wide range of complex shapes and intricate designs.
- This method creates no mechanical force.
- EDM offers a smooth and fine surface finish.
Limitations
- EDM is a slow process.
- Only works with conductive materials
