What Is EDM Machining?
EDM machining—used by shops in Spokane, WA—cuts conductive metals using sparks, not blades. It all happens underwater in dielectric fluid.
EDM doesn’t cut—it erodes. That’s why it excels at machining complex geometries, deep cavities, and exotic metals without leaving burrs behind.
At Roberson Machine Company, we use EDM machining for Spokane, WA, 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: 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 custom dies or form tools required—ideal for short runs, revisions, or highly custom parts.
- Finish-Ready: Burr-free results reduce—or eliminate—the need for post-processing and cleanup.
Together, these advantages help reduce secondary operations and material waste while improving speed and efficiency.
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.
Many Spokane, WA, 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: 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: High-precision components that reduce friction, resist wear, and keep production lines running fast.
- Food & Beverage: Smooth, burr-free parts designed for food contact and harsh sanitation protocols.
- Oil & Energy: For parts exposed to saltwater, heat, and abrasive flow—EDM delivers dimensional integrity and strength.
- Automation & Robotics: Intricate geometries and complex cutouts for custom jigs, nests, and end-effectors.
- Firearm Manufacturing: Internal components and slide mechanisms that require precision machining and repeatable accuracy.
- Consumer & Commercial Products: EDM is ideal for small-batch production, detailed branding dies, and precision enclosures.
- OEM & Custom Applications: Whether it’s titanium, carbide, or copper—in short runs or large volumes—EDM cuts it clean.
Whether you need complex parts or consistent production, our EDM capabilities are engineered for precision and durability. Meet our team and see how we’ve supported U.S. manufacturers for over 20 years.
EDM Machining: Materials We Work With
For Spokane, WA, businesses working with exotic metals or hardened alloys, EDM machining offers the precision and finish traditional tools can’t deliver—without the thermal damage.
