Wire Cut EDM for Hardened Tooling and Parts
Because the wire never touches the part, wire EDM cuts hardened tool steel as fast as soft metal. Dies and punches go through heat treatment first, then straight to final profiling, with no re-softening and no dimensional drift.
Over 20+ years, our CNC machining China operation has machined 1.2M+ parts a year for 2,300+ OEM clients. One replacement punch gets the same engineering review as a 500-piece run. See how the process works in All You Need to Know about Wire Cut EDM.
Why Toolmakers Choose DEK for Wire EDM
Mold builders, die shops and OEMs without in-house EDM route hardened, tight-tolerance work to our wire EDM floor.
-
Cut After Hardening
Hardened tool steel and heat-treated alloys cut at the same rate as soft metal, so heat treatment happens before final profiling, not after.
-
No-Contact Cutting
The wire never touches the workpiece: no cutting force, no tool deflection and no distortion in thin or delicate sections.
-
No MOQ, Any Run Size
Single prototypes through production runs. Prototypes ship in as fast as 3 days, whether it is one hardened insert or a production batch.
-
Tight, Repeatable Profiles
±0.005 mm on production profiles, tightening to ±0.003 mm on micro and sub-10 mm features, with dimensions holding through repeat runs.
Engineering Review on Every Job
Our engineers check manufacturability and confirm wire EDM is the right process for your geometry, versus milling or sinker EDM, before quoting. Parts needing a mirror finish or tighter flatness are routed to grinding.
Wire EDM Capabilities & Specs
Part size, tolerances, materials and applications for wire-cut profiles in hardened and conductive metals.
Wire EDM vs. Sinker EDM and CNC Milling
Choose wire EDM for cut-through profiles in hardened metal. Both wire and sinker sit under our EDM machining service, so one request routes to the right method.
| Criteria | This ProcessWire EDM | Sinker EDM | CNC Milling |
|---|---|---|---|
| Best for | Cut-through profiles | Cavities and 3D forms | Lighter structural parts |
| Tool | Moving wire electrode | Machined, shaped electrode | End mill cutter |
| Hardened metal | Same rate as soft metal | Spark erosion | Speed depends on hardness |
| Cutting force | None, no contact | Spark erosion | Tool deflection risk |
| Choose when | Sharp corners, thin walls | Pocket or blind form | Aluminum, mild steel parts |

Wire EDM Features & Challenges We Solve
Spark erosion cuts geometries that would need small end mills and multiple setups, or be impossible, on hardened material.
-
Sharp Inside Corners
Profiles that would chip a mill cutter or need multiple setups come off in one pass, burr-free.
-
Thin Walls & Fine Slots
No cutting force means no distortion in thin or delicate sections, even on hardened material.
-
Punch & Die Relief Angles
Taper cutting produces relief angles directly in the same setup, with no secondary angled fixture.
-
Micro Features Under 10 mm
Held to ±0.003 mm on sub-10 mm features; see our micro machining services.
-
Profiles up to 1000 mm
Part envelope up to 1000 mm in the largest dimension, from thin sheet stock to thick tool steel blocks.
-
Wire-Cut Plus Turned Features
A shaft with a splined end can move between wire EDM and Swiss CNC turning on one job.
Common Challenges We Handle
-
Hardened Tool Steel
Dies go through heat treatment first, then straight to the wire, avoiding the risk of milling soft and hoping tolerance holds afterward.
-
Tungsten Carbide
Wear parts and electrodes are cut from tungsten steel and carbide, materials that resist conventional cutting.
-
Post-Heat-Treat Drift
No re-softening and no second heat treatment cycle, so there is no dimensional drift between hardening and final profiling.
-
Mirror Finish or Flatness
When skim passes are not enough for a finish or flatness spec, parts are routed through precision grinding after cutting.
Certified Quality for Wire-Cut Parts
Every order runs through IQC, IPQC, FAI, OQC, SPC and CAPA, with CMM inspection.
