What Is EDM Machining?
EDM machining—used by shops in Charlotte, NC—cuts conductive metals using sparks, not blades. It all happens underwater in dielectric fluid.
EDM machines don’t slice—they spark. It’s the go-to process for high-precision work in metals that laugh at conventional tools.
EDM machining at Roberson Machine Company supports Charlotte, NC, 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: No special fixtures needed, which makes EDM great for fast-turn projects and low-volume jobs.
- Finish-Ready: Burr-free results reduce—or eliminate—the need for post-processing and cleanup.
By reducing unnecessary steps and material waste, EDM helps streamline production and speed up delivery.
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 Charlotte, NC, sectors rely on EDM machining, including:
- Aerospace: Engineered for flight—EDM creates mission-critical parts with unmatched precision.
- Military & Defense: EDM produces tight-tolerance parts for advanced weapon systems, surveillance gear, and armored vehicles.
- 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: Sanitary-grade EDM components in corrosion-resistant stainless and specialty alloys for washdown environments.
- Oil & Energy: For parts exposed to saltwater, heat, and abrasive flow—EDM delivers dimensional integrity and strength.
- Automation & Robotics: EDM supports precision parts for motion-critical assemblies and automated tooling.
- Firearm Manufacturing: EDM helps manufacture precision fire control systems, locking lugs, and receivers.
- Consumer & Commercial Products: Low-volume, high-precision EDM parts for commercial devices and consumer-facing products.
- OEM & Custom Applications: EDM supports custom and OEM builds from prototype through scale-up, across material types.
With decades of proven results, our EDM machining supports projects that demand consistent, high-performance output. Learn more about our team and our nationwide reach.
