What Is EDM Machining?
Raleigh, NC, EDM machining is a non-contact process that uses controlled electrical sparks to cut conductive materials. Thousands of rapid discharges occur between an electrode and the workpiece—submerged in dielectric fluid—to remove material without any physical cutting tools or direct contact.
EDM machines don’t slice—they spark. It’s the go-to process for high-precision work in metals that laugh at conventional tools.
At Roberson Machine Company, we use EDM machining for Raleigh, NC, 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 stands out for its ability to handle complex, high-precision work with ease.
- No Mechanical Stress: With no cutting force involved, EDM handles fragile geometries and thin-walled parts without risk of distortion.
- Range of Materials: EDM works on metals traditional tools struggle with—ideal for hardened, heat-treated, or exotic materials.
- Zero Tooling Costs: Skip the upfront tooling—perfect for prototypes, design tweaks, and one-off parts.
- 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 fills the gap where traditional tooling fails—especially in industries that need complex, ultra-precise parts made from hardened alloys.
Industries in Raleigh, NC, that use EDM machining include:
- Aerospace: Tight-tolerance parts for engines, airframes, and flight systems start with precision EDM.
- Military & Defense: Built to withstand heat, impact, and stress—EDM machining meets military-grade specs.
- 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: Clean cuts and durable tooling for precise forming, sealing, and stamping processes.
- Food & Beverage: Sanitary-grade EDM components in corrosion-resistant stainless and specialty alloys for washdown environments.
- Oil & Energy: Precision-cut parts for turbines, seals, and tooling used in high-pressure, high-temperature 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: EDM is ideal for small-batch production, detailed branding dies, and precision enclosures.
- OEM & Custom Applications: EDM gives OEMs and R&D teams a way to cut parts that traditional tools can’t handle.
