What Is EDM Machining?
Instead of cutting with tools, Minneapolis, MN, EDM machining uses rapid electrical sparks between an electrode and the material—submerged in dielectric fluid.
Think of EDM as metal shaping with controlled lightning—great for tight tolerances, hard materials, and parts that need a perfect finish the first time.
We help Minneapolis, MN, companies across medical, aerospace, and defense sectors get repeatable, accurate results with advanced EDM machining. Learn more at Roberson Machine Company.
Key Advantages of EDM Machining
Few processes match EDM when it comes to intricate, ultra-precise machining tasks.
- No Mechanical Stress: EDM gently removes material without pressure, making it a smart choice for precision features in fragile designs.
- 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: 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
From aerospace to medical devices, industries turn to EDM machining when materials are too tough or geometries too tight for conventional methods.
You’ll find EDM machining in Minneapolis, MN, industries such as:
- Aerospace: From jet engines to structural supports, EDM helps meet strict aerospace standards.
- Military & Defense: Built to withstand heat, impact, and stress—EDM machining meets military-grade specs.
- Automotive: From drivetrain parts to connectors, EDM supports efficient, accurate machining at every stage.
- Medical: From orthopedic implants to custom surgical tools, EDM meets tight tolerances with clean finishes.
- Packaging: High-precision components that reduce friction, resist wear, and keep production lines running fast.
- Food & Beverage: EDM machining for stainless and food-safe alloys used in sanitary processing equipment.
- Oil & Energy: EDM handles the hard alloys and deep geometries common in turbines, valves, and drilling systems.
- Automation & Robotics: High-precision EDM parts for fixtures, housings, and movement-critical systems in automated workflows.
- Firearm Manufacturing: EDM supports consistent, high-accuracy production of firearm components.
- Consumer & Commercial Products: Ideal for prototypes and short runs—EDM supports fast iteration and tight detail.
- OEM & Custom Applications: EDM gives OEMs and R&D teams a way to cut parts that traditional tools can’t handle.
