Wire EDM Services: Tight-Tolerance Profiles in Hard Metals
Wire EDM cuts precision profiles through hardened and delicate parts using a thin, continuously fed brass wire as the electrode—no cutting force, no distortion, and tolerance for shapes that would defeat a bandsaw or mill. For tooling, fixtures, and exotic alloys, wire EDM is the cleanest way to slice complex 2D contours. This guide covers how it works, when to choose it, the materials it handles, and how to spec your job.
How Wire EDM Works
A fine wire (typically 0.1–0.3 mm brass) threads through the workpiece while sparks erode a kerf along the programmed path, all submerged in dielectric. Because there’s no mechanical contact, even paper-thin or fully hardened parts cut without deflection. It’s the natural partner to sinker EDM and CNC milling for finished tooling.
Wire EDM vs. Other Cutting
Versus milling, wire EDM cuts hardened stock and extremely thin features without tool pressure. Versus laser, it handles thick, conductive parts with superior edge quality and no heat-affected zone. Choose wire EDM for tight-tolerance profiles in hard materials.
Materials We Cut
- Hardened tool and die steels — the primary use.
- Tungsten carbide and ceramics — with appropriate wire.
- Titanium and Inconel — where milling is slow.
- Stainless and alloy steels — for precision components.
- Aluminum and copper — for fixtures and details.
Industries That Rely on Wire EDM
Tool and die, aerospace, medical, and electronics all use wire EDM for punches, inserts, and prototypes in hard materials. It’s how complex profiles get made accurately and repeatably.
How to Spec Your Wire EDM Job
- Send the 2D profile or 3D model with tolerances.
- State material and thickness—drives wire and taper.
- Define corner radii and finish requirements.
- Note any tapers the machine can cut.
- Share quantity to plan setup.
FAQ
What tolerance can wire EDM hold?
We routinely hold ±0.005 mm on profile features in thick stock.
Can it cut hardened steel?
Yes—hardened material is ideal for wire EDM, with no heat-affected zone.
How thick can it cut?
We handle substantial sections; thicker stock simply takes longer.
