What Is EDM Machining?
Instead of cutting with tools, Spartanburg, SC, EDM machining uses rapid electrical sparks between an electrode and the material—submerged in dielectric fluid.
Think of EDM as metal shaping with controlled lightning—great for tight tolerances, hard materials, and parts that need a perfect finish the first time.
When Spartanburg, SC, parts need precision, Roberson Machine Company delivers—especially for defense, medical, and aerospace applications with strict tolerances.
Key Advantages of EDM Machining
EDM is built for challenges that demand accuracy, intricacy, and consistency.
- 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: 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.
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
EDM machining fills the gap where traditional tooling fails—especially in industries that need complex, ultra-precise parts made from hardened alloys.
You’ll find EDM machining in Spartanburg, SC, industries such as:
- Aerospace: Engineered for flight—EDM creates mission-critical parts with unmatched precision.
- Military & Defense: Durable components for extreme conditions—EDM supports defense systems where failure isn’t an option.
- Automotive: Custom tooling and complex geometries for powertrain systems, mold inserts, and electrical components.
- Medical: EDM enables ultra-precise machining of surgical-grade materials like titanium and stainless steel.
- Packaging: Clean cuts and durable tooling for precise forming, sealing, and stamping processes.
- Food & Beverage: EDM helps manufacture hygienic-grade parts that hold up to caustics, steam, and pressure washing.
- Oil & Energy: EDM handles the hard alloys and deep geometries common in turbines, valves, and drilling systems.
- Automation & Robotics: Tight-tolerance components for robotic arms, linear guides, and control systems.
- Firearm Manufacturing: Tight fits and repeatable performance for triggers, slides, and internal assemblies.
- Consumer & Commercial Products: Clean edges and exact details for custom consumer products and branded tooling.
- 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.
