What Is EDM Machining?
This Madison, WI, EDM machining method relies on rapid electrical discharges, not tooling, to erode conductive materials submerged in dielectric fluid.
Think of it like carving metal with lightning. EDM is ideal for hard or exotic metals, tight internal features, and complex shapes that conventional machining can’t easily reach. It also produces clean, burr-free finishes that often require no secondary processing.
For Madison, WI, manufacturers that need complex, high-accuracy components, Roberson Machine Company delivers dependable EDM machining solutions.
Key Advantages of EDM Machining
When precision and complexity collide, EDM is the go-to solution.
- No Mechanical Stress: EDM removes material without force. This makes it ideal for fragile geometries, thin walls, or delicate internal components.
- Range of Materials: Hardened steel, titanium, carbide—EDM cuts materials traditional tools can’t touch.
- Zero Tooling Costs: EDM eliminates the need for custom tooling, saving time and money on small or evolving projects.
- Finish-Ready: With EDM, your parts are often ready to ship or assemble without extra touchups.
Together, these advantages help reduce secondary operations and material waste while improving speed and efficiency.
Industries That Use EDM Machining
EDM machining is used across industries where traditional tooling can’t cut it—literally. From aerospace assemblies to medical-grade components, this process is essential for producing intricate, high-precision parts in tough materials.
Madison, WI, EDM machining supports a wide range of industries, including:
