What Is EDM Machining?
In Wilmington, NC, EDM machining removes metal using thousands of tiny sparks—no physical contact required. It all happens inside a bath of dielectric fluid.
It’s like carving with electricity—EDM works where traditional cutting tools can’t, especially on hard metals and fine internal features. And the finish? Clean and burr-free.
EDM machining at Roberson Machine Company supports Wilmington, NC, industries that demand extreme precision—like aerospace, energy, and medical manufacturing.
Key Advantages of EDM Machining
EDM offers several advantages that make it ideal for complex, high-precision work.
- No Mechanical Stress: EDM removes material without force. This makes it ideal for fragile geometries, thin walls, or delicate internal components.
- Range of Materials: Tough alloys like carbide and hardened steel are no problem—EDM cuts what others can’t.
- Zero Tooling Costs: No special fixtures needed, which makes EDM great for fast-turn projects and low-volume jobs.
- Finish-Ready: Parts come off the EDM machine with smooth, precise edges—no deburring required.
Together, these advantages help reduce secondary operations and material waste while improving speed and efficiency.
Industries That Use EDM Machining
EDM machining is critical in sectors where complexity and material strength rule out traditional tools—from turbine blades to implantable components.
Wilmington, NC, EDM machining supports a wide range of industries, including:
- Aerospace: EDM machining delivers accuracy for turbine blades, engine components, and aerospace structures.
- Military & Defense: EDM machining for hardened alloys, mission-critical assemblies, and components built for high-heat and high-impact environments.
- Automotive: EDM creates high-precision parts for transmissions, injection molds, and control modules.
- Medical: Biocompatible materials, ultra-clean cuts—EDM supports life-critical medical manufacturing.
- Packaging: Forming dies and precision wear parts with clean finishes and minimal post-processing for fast-moving production lines.
- Food & Beverage: EDM helps manufacture hygienic-grade parts that hold up to caustics, steam, and pressure washing.
- Oil & Energy: Components for power gen, petrochem, and upstream systems made with clean, exact EDM cuts.
- Automation & Robotics: Tight-tolerance components for robotic arms, linear guides, and control systems.
- Firearm Manufacturing: Reliable machining for toleranced parts used in handguns, rifles, and specialty platforms.
- Consumer & Commercial Products: EDM support for housings, branding dies, and custom fixtures in low- and mid-volume production runs.
- OEM & Custom Applications: Whether it’s titanium, carbide, or copper—in short runs or large volumes—EDM cuts it clean.
