Wire EDM & Hard-Material Machining
Cut hardened steel, carbide, and exotic alloys with no cutting force — reaching internal corners and fine features that milling cannot. Sodick wire EDM, verified measurement, per-shipment inspection.
Wire EDM (electrical discharge machining) removes material by spark, not by a cutting tool. Because there is no mechanical force, it machines hardened and fragile parts that would deflect, crack, or work-harden under a mill — and it reaches true internal corners, thin slots, and fine detail other processes cannot.
Why EDM, why here
Hard materials, as-received
Machine hardened tool steel, carbide, and heat-treated alloys after hardening — no annealing, no softening step.
Internal corners & fine features
True sharp internal radii, narrow slots, and burr-free detail that a rotating cutter can never reach.
No cutting force
Thin-walled and fragile parts stay true. The wire never pushes the workpiece out of shape.
On the floor
EDM runs in the same verified, measurement-first environment as our CNC and grinding — so a part can move from mill to wire to grind and back without leaving the network.
| Capability | Detail |
|---|---|
| Process | Sodick wire EDM |
| Holding tolerance | ±0.005 mm (finer with finish skim) |
| Best for | Hardened steel, carbide, exotic alloys, thin-wall & fine-feature parts |
| Finish | Burr-free, no mechanical stress |
Where EDM earns its place
When a part needs what cutting cannot deliver.
Inserts and components with sharp internal corners.
Machine after heat-treat, no re-softening.
Wear-resistant and dimensionally stable.
Fragile geometry stays true, no force.
Real parts from solid hardened material.
Combine EDM with CNC in one flow.
Milling-only vs. Lanser
| Need | Milling only | With wire EDM |
|---|---|---|
| Internal corner in hardened steel | Cannot — cutter radius limits it | True sharp internal radius |
| Hardened part after heat-treat | Risk of work-hardening or cracking | Routine, no force |
| Thin slot or fine slit | Limited by tool diameter | Down to fine wire width |
| Fragile or thin-wall part | Deflects under cutting load | Stays true |
A part that needs what cutting can’t do?
Send the drawing — hardened material, tight internal features, or a thin-wall part — and we will route it through CNC, wire EDM, and grinding as one job, with a clear quote usually within 24 hours.
