What Is Wire EDM Machining? | [city, OK, Precision CNC Services
Wire EDM is one of the specialized services included in our broader CNC machining capabilities. Wire EDM replaces direct cutting tools with a thin, charged wire to shape conductive metals. Material is removed by controlled sparks along a programmed wire path, achieving exact cuts without mechanical stress on components.
This process is perfect for geometries and materials beyond conventional machining: intricate profiles, fine slots, tight internal corners, and hardened or exotic alloys like titanium and carbide. Cuts leave the machine accurate, smooth, and immediately ready for further assembly or finishing.
Real-World Applications for Tulsa, OK, Wire EDM and Precision Cutting
Use wire EDM for jobs where standard machining can’t meet geometry, surface, or tolerance specs—like hard alloys, thin-walled parts, or components sensitive to cutting forces. Conductive metals like titanium, carbide, Inconel, and hardened steels are cut cleanly and burr-free with wire EDM.
From prototypes and fixtures to complete production runs, teams across Tulsa, OK, rely on wire EDM. Frequent applications include:
- Aerospace: Intricate turbine slots, seal features, and precision tooling inserts that hold tight tolerances after heat treat.
- Military & Defense: Critical defense assemblies and hardened alloys machined burr-free with tight internal edges.
- Automotive: Precision powertrain tools, prototype components, and mold inserts designed with tight internal features.
- Medical: Surgical tools, implant parts, and micro features machined burr-free in biocompatible alloys.
- Packaging: Sharp-edged forming dies and smooth wear parts designed to limit secondary finishing.
- Food & Beverage: Washdown-ready stainless parts, corrosion-resistant and machined without added stress.
- Oil & Energy: High-pressure pump parts, sealing surfaces, and alloy components engineered for harsh service.
- Automation & Robotics: Automation parts such as fixtures, housings, and moving elements cut with tight tolerances.
- Firearm Manufacturing: Consistently accurate firearm slides, internals, and tooling with sharp, burr-free edges.
- Consumer & Commercial Products: Branding dies, custom fixtures, and low- to mid-volume precision parts.
- OEM & Custom Applications: Whether it’s an R&D part or production in exotic alloys, if it’s conductive, wire EDM cuts it.
