What Is EDM Machining?
In Santa Rosa, CA, EDM machining removes metal using thousands of tiny sparks—no physical contact required. It all happens inside a bath of 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.
At Roberson Machine Company, we use EDM machining for Santa Rosa, CA, companies to create highly precise parts for aerospace, defense, energy, and medical applications—especially when accuracy, complexity, and repeatability are critical.
Key Advantages of EDM Machining
EDM offers several advantages that make it ideal for complex, high-precision work.
- No Mechanical Stress: EDM gently removes material without pressure, making it a smart choice for precision features in fragile designs.
- 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: EDM creates surfaces so clean they often skip additional processing entirely.
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.
Many Santa Rosa, CA, sectors rely on EDM machining, including:
- Aerospace: Tight-tolerance parts for engines, airframes, and flight systems start with precision EDM.
- Military & Defense: Precision machining for rugged, high-stakes environments including combat and aerospace platforms.
- Automotive: Custom tooling and complex geometries for powertrain systems, mold inserts, and electrical components.
- 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: Machined accuracy for robotic frames, couplings, and motion systems.
- Firearm Manufacturing: EDM supports consistent, high-accuracy production of firearm components.
- Consumer & Commercial Products: Ideal for prototypes and short runs—EDM supports fast iteration and tight detail.
- OEM & Custom Applications: From single-part test runs to full-on production, EDM fits wherever complexity and conductivity meet.
