What Is EDM Machining?
Instead of cutting with tools, Duluth, MN, EDM machining uses rapid electrical sparks between an electrode and the material—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.
EDM machining at Roberson Machine Company supports Duluth, MN, industries that demand extreme precision—like aerospace, energy, and medical manufacturing.
Key Advantages of EDM Machining
Few processes match EDM when it comes to intricate, ultra-precise machining tasks.
- No Mechanical Stress: The non-contact process protects fine features and internal details that traditional tools might damage.
- Range of Materials: From titanium to tool steel, EDM makes clean, precise cuts in the hardest materials.
- Zero Tooling Costs: With no form tools required, EDM streamlines production of custom or changing part designs.
- Finish-Ready: With EDM, your parts are often ready to ship or assemble without extra touchups.
EDM’s efficiency helps shrink both material waste and time spent on secondary processes.
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.
Duluth, MN, EDM machining supports a wide range of industries, including:
- Aerospace: Tight-tolerance parts for engines, airframes, and flight systems start with precision EDM.
- Military & Defense: Durable components for extreme conditions—EDM supports defense systems where failure isn’t an option.
- Automotive: From drivetrain parts to connectors, EDM supports efficient, accurate machining at every stage.
- Medical: Biocompatible materials, ultra-clean cuts—EDM supports life-critical medical manufacturing.
- Packaging: EDM creates sharp, durable tooling for high-speed packaging systems and forming dies.
- Food & Beverage: Clean finishes and corrosion-resistant materials for FDA-compliant machine parts.
- Oil & Energy: EDM machining supports rugged, corrosion-resistant parts for energy and drilling applications.
- Automation & Robotics: Intricate geometries and complex cutouts for custom jigs, nests, and end-effectors.
- Firearm Manufacturing: EDM supports consistent, high-accuracy production of firearm components.
- Consumer & Commercial Products: Custom machined parts for consumer goods, enclosures, and commercial prototypes.
- OEM & Custom Applications: From R&D prototypes to long-run production in exotic or hard-to-machine materials—if it’s conductive, we can cut it.

EDM Machining: Materials We Work With
Because EDM machining only works on conductive materials, it’s ideal for Duluth, MN, manufacturers dealing with tough metals like titanium, steel, and copper.
- Aluminum (6061, 7075, 7050): Known for a strong strength-to-weight ratio, these alloys are used in everything from brackets to performance-grade parts. See what’s possible with aluminum CNC machining.
- Stainless Steel (303, 304, 316, 321, 420, 416, 440): EDM machining is well-suited for these durable steels used in aerospace, food-grade, and medical-grade components.
- Brass and Copper: Highly machinable and conductive; brass and copper alloys are ideal for electrical contacts, connectors, and fluid-handling parts.
- Titanium: For tough, heat-resistant applications, titanium excels—EDM machining offers clean, precise results in this premium alloy.
- Tool Steels and Carbides: EDM machining is one of the few effective methods for cutting hardened steels (like D2, A2, H13) and tungsten carbide used in dies, molds, and wear parts.
