What Is EDM Machining?
EDM machining—used by shops in Durham, NC—cuts conductive metals using sparks, not blades. It all happens underwater in dielectric fluid.
EDM machines don’t slice—they spark. It’s the go-to process for high-precision work in metals that laugh at conventional tools.
When Durham, NC, parts need precision, Roberson Machine Company delivers—especially for defense, medical, and aerospace applications with strict tolerances.
Key Advantages of EDM Machining
EDM offers several advantages that make it ideal for complex, high-precision work.
- No Mechanical Stress: Because EDM doesn’t rely on physical contact, it’s ideal for delicate shapes and sensitive internal structures.
- Range of Materials: EDM handles materials that conventional machining can’t, from titanium to carbide to hardened steels.
- Zero Tooling Costs: Skip the upfront tooling—perfect for prototypes, design tweaks, and one-off parts.
- Finish-Ready: Sharp detail and smooth edges mean EDM parts are production-ready right off the machine.
These benefits combine to minimize secondary steps and cut down on material waste, helping jobs move faster with less overhead.
Industries That Use EDM Machining
This process shows up wherever detail, precision, and durability matter—EDM machining powers industries that need to do more than just remove metal.
From aerospace to energy, Durham, NC, EDM machining plays a role across industries like:
- Aerospace: From jet engines to structural supports, EDM helps meet strict aerospace standards.
- Military & Defense: Built to withstand heat, impact, and stress—EDM machining meets military-grade specs.
- Automotive: From drivetrain parts to connectors, EDM supports efficient, accurate machining at every stage.
- Medical: Burr-free micro components machined in titanium and other biocompatible materials for surgical tools, implants, and diagnostic equipment.
- Packaging: Fast, repeatable results for cutting tools, forming dies, and machine components in packaging equipment.
- Food & Beverage: Smooth, burr-free parts designed for food contact and harsh sanitation protocols.
- Oil & Energy: EDM handles the hard alloys and deep geometries common in turbines, valves, and drilling systems.
- Automation & Robotics: Machined accuracy for robotic frames, couplings, and motion systems.
- Firearm Manufacturing: EDM helps manufacture precision fire control systems, locking lugs, and receivers.
- Consumer & Commercial Products: Clean edges and exact details for custom consumer products and branded tooling.
- OEM & Custom Applications: EDM supports custom and OEM builds from prototype through scale-up, across material types.
