What Is EDM Machining?
Fayetteville, AR, EDM machining is a non-contact process that uses controlled electrical sparks to cut conductive materials. Thousands of rapid discharges occur between an electrode and the workpiece—submerged in dielectric fluid—to remove material without any physical cutting tools or direct contact.
EDM machines don’t slice—they spark. It’s the go-to process for high-precision work in metals that laugh at conventional tools.
For Fayetteville, AR, manufacturers that need complex, high-accuracy components, Roberson Machine Company delivers dependable EDM machining solutions.
Key Advantages of EDM Machining
EDM is built for challenges that demand accuracy, intricacy, and consistency.
- No Mechanical Stress: EDM cuts without applying force, making it perfect for thin walls, fine features, and fragile components.
- Range of Materials: EDM works on metals traditional tools struggle with—ideal for hardened, heat-treated, or exotic materials.
- Zero Tooling Costs: EDM eliminates the need for custom tooling, saving time and money on small or evolving projects.
- Finish-Ready: Burr-free results reduce—or eliminate—the need for post-processing and cleanup.
By reducing unnecessary steps and material waste, EDM helps streamline production and speed up delivery.
Industries That Use EDM Machining
When conventional tools fall short, EDM machining delivers. It’s relied on across industries for creating intricate, high-precision parts from hard-to-machine materials.
