What Is EDM Machining?
In Chattanooga, TN, EDM machining removes metal using thousands of tiny sparks—no physical contact required. It all happens inside a bath of 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.
Roberson Machine Company provides EDM machining for Chattanooga, TN, businesses in industries like aerospace, medical, and defense—where precision matters most.
Key Advantages of EDM Machining
EDM offers several advantages that make it ideal for complex, high-precision work.
- No Mechanical Stress: EDM removes material without force. This makes it ideal for fragile geometries, thin walls, or delicate internal components.
- Range of Materials: Tough alloys like carbide and hardened steel are no problem—EDM cuts what others can’t.
- Zero Tooling Costs: With no form tools required, EDM streamlines production of custom or changing part designs.
- 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 is used across industries where traditional tooling can’t cut it—literally. From aerospace assemblies to medical-grade components, this process is essential for producing intricate, high-precision parts in tough materials.
Chattanooga, TN, EDM machining supports a wide range of industries, including:
- Aerospace: Tight-tolerance parts for engines, airframes, and flight systems start with precision EDM.
- Military & Defense: Durable components for extreme conditions—EDM supports defense systems where failure isn’t an option.
- Automotive: EDM creates high-precision parts for transmissions, injection molds, and control modules.
- Medical: Burr-free micro components machined in titanium and other biocompatible materials for surgical tools, implants, and diagnostic equipment.
- Packaging: High-precision components that reduce friction, resist wear, and keep production lines running fast.
- Food & Beverage: Washdown-tough and sanitary—EDM produces clean parts for food processing and packaging systems.
- Oil & Energy: For parts exposed to saltwater, heat, and abrasive flow—EDM delivers dimensional integrity and strength.
- Automation & Robotics: EDM delivers parts that keep automation precise, consistent, and fast.
- 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.
