What Is EDM Machining?
EDM machining—used by shops in Little Rock, AR—cuts conductive metals using sparks, not blades. It all happens underwater in dielectric fluid.
Picture lightning sculpting metal. That’s EDM: a spark-based process perfect for tight corners, hard alloys, and zero-touch results with minimal cleanup.
At Roberson Machine Company, we use EDM machining for Little Rock, AR, 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 cuts without applying force, making it perfect for thin walls, fine features, and fragile components.
- Range of Materials: EDM works on metals traditional tools struggle with—ideal for hardened, heat-treated, or exotic materials.
- Zero Tooling Costs: With no form tools required, EDM streamlines production of custom or changing part designs.
- Finish-Ready: Parts come off the EDM machine with smooth, precise edges—no deburring required.
The result? Faster cycles, less material waste, and fewer post-processing steps.
Industries That Use EDM Machining
From aerospace to medical devices, industries turn to EDM machining when materials are too tough or geometries too tight for conventional methods.
Little Rock, AR, 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: 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: Precision micro-machining for components used in minimally invasive instruments and diagnostic devices.
- Packaging: Fast, repeatable results for cutting tools, forming dies, and machine components in packaging equipment.
- Food & Beverage: EDM machining for stainless and food-safe alloys used in sanitary processing equipment.
- Oil & Energy: EDM machining supports rugged, corrosion-resistant parts for energy and drilling applications.
- Automation & Robotics: EDM supports precision parts for motion-critical assemblies and automated tooling.
- Firearm Manufacturing: Reliable machining for toleranced parts used in handguns, rifles, and specialty platforms.
- Consumer & Commercial Products: EDM support for housings, branding dies, and custom fixtures in low- and mid-volume production runs.
- OEM & Custom Applications: From single-part test runs to full-on production, EDM fits wherever complexity and conductivity meet.
Roberson Machine Company brings decades of EDM experience to industries that need precision they can count on. Learn about our team and our coast-to-coast partnerships.
EDM Machining: Materials We Work With
Because EDM machining only works on conductive materials, it’s ideal for Little Rock, AR, manufacturers dealing with tough metals like titanium, steel, and copper.
- Aluminum (6061, 7075, 7050): Known for a strong strength-to-weight ratio, these alloys are used in everything from brackets to performance-grade parts. See what’s possible with aluminum CNC machining.
- Stainless Steel (303, 304, 316, 321, 420, 416, 440): EDM machining is well-suited for these durable steels used in aerospace, food-grade, and medical-grade components.
- Brass and Copper: Excellent conductivity and workability make these metals ideal for precision fluid and electrical parts.
- Titanium: Titanium’s material properties make it perfect for precise, burr-free EDM cuts used in medical and aerospace assemblies.
- Tool Steels and Carbides: For hardened steels like H13 or difficult alloys like tungsten carbide, EDM is the go-to for precise, stress-free cuts.
