What Is Wire EDM Machining? | [city, CA, Precision CNC Services
We include wire EDM as a specialized option within our wider CNC machining capabilities. Instead of using a cutting tool that physically contacts the workpiece, wire EDM shapes conductive metals with a thin, electrically charged wire. The process forms controlled sparks along the wire path, eroding material into highly accurate cuts without stressing the part.
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. Parts come off the machine precise, burr-free, and ready to move straight into the next step of your build.
Real-World Applications for Sacramento, CA, 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. Wire EDM cuts conductive metals cleanly and burr-free, including titanium, carbide, Inconel, hardened steels, and more.
Wire EDM in Sacramento, CA, supports prototypes, tooling fixtures, and full-scale production jobs. Examples of applications include:
- Aerospace: Complex turbine slots, sealing features, and precision tooling inserts that stay accurate through heat treat.
- Military & Defense: Critical defense assemblies and hardened alloys machined burr-free with tight internal edges.
- Automotive: Complex powertrain tooling, mold inserts, and prototype parts with fine internal clearances.
- Medical: Biocompatible metal implants, surgical devices, and micro features produced clean and burr-free.
- Packaging: Forming dies and wear components machined with sharp profiles and smooth surfaces for less post-processing.
- Food & Beverage: Washdown-ready stainless parts, corrosion-resistant and machined without added stress.
- Oil & Energy: Precision sealing surfaces, pump components, and alloy parts for high-pressure, corrosive service.
- Automation & Robotics: Automation parts such as fixtures, housings, and moving elements cut with tight tolerances.
- Firearm Manufacturing: Slides, internal components, and tooling where repeatable accuracy and clean edges matter.
- Consumer & Commercial Products: Precision branding dies, fixtures, and parts for consumer and commercial applications.
- OEM & Custom Applications: R&D prototypes to production in exotic or hardened materials—if it conducts, wire EDM handles it.
