What Is Wire EDM Machining? | [city, CT, Precision CNC Services
Within our full range of CNC machining services, wire EDM stands out as a specialized process. Instead of using a cutting tool that physically contacts the workpiece, wire EDM shapes conductive metals with a thin, electrically charged wire. The wire produces controlled sparks that erode material along a programmed path, creating extremely accurate cuts with no mechanical stress on the part or component.
It’s particularly suited for work conventional tools can’t handle: detailed profiles, slim slots, sharp internal corners, and parts in hardened steels, titanium, carbide, or similar alloys. Every cut comes off the machine accurately, clean, and ready for whatever comes next in your build.
Real-World Applications for Hartford, CT, Wire EDM and Precision Cutting
When geometry, finish, or tolerance demands are beyond conventional tooling—especially with tough materials, thin walls, or fragile parts—wire EDM is the solution. Conductive metals like titanium, carbide, Inconel, and hardened steels are cut cleanly and burr-free with wire EDM.
Wire EDM in Hartford, CT, supports prototypes, tooling fixtures, and full-scale production jobs. Examples of applications include:
- Aerospace: Precision turbine slots, seal details, and tooling inserts that maintain tolerances after heat treating.
- Military & Defense: Distortion-free cuts in hardened alloys and defense-grade assemblies with sharp internal geometry.
- 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: Forming dies and wear components machined with sharp profiles and smooth surfaces for less post-processing.
- Food & Beverage: Food-grade stainless components built for washdown service, free from stress or burrs.
- Oil & Energy: Precision-machined sealing surfaces, pump hardware, and alloys that withstand corrosive environments.
- Automation & Robotics: Precision fixtures, housings, and motion assemblies designed with close internal clearances.
- Firearm Manufacturing: Slides, tooling, and inner firearm parts manufactured with clean edges and repeatable tolerances.
- Consumer & Commercial Products: Custom fixtures, precision parts, and branding dies for commercial and consumer products.
- OEM & Custom Applications: Prototype one-offs through full production runs in hardened or exotic alloys—if conductive, we cut it.
