Wire EDM

Precision wire cutting in hardened material — ±0.0002" tolerance, no cutting force, sharp internal corners, and 0.020" kerf for precision splitting.

Wire EDM cuts conductive material using a controlled electrical spark along a thin brass wire. There is no cutting force — nothing pushes on the workpiece, nothing deflects, nothing leaves a corner radius. Our CHMER G32S wire EDM holds ±0.0002" tolerance on features that cannot be produced any other way: tight-tolerance keyways and splines, precision slots in hardened steel, complex 2D profiles with internal sharp corners, and precision splitting operations where as little as 0.020" of material is removed. Hardness is irrelevant to the process — we cut hardened tool steel, carbide, and exotic alloys just as cleanly as soft stock.

CAPABILITIES

What We Deliver

Industry-standard processes documented at every step.

Tight-tolerance slots, keyways, and splines — ±0.0002"
Precision splitting with 0.020" kerf — minimum material removal
Internal sharp corners — no cutter radius left behind
Complex 2D profiles and contours in a single setup
Through-cuts in hardened tool steel, carbide, and exotic alloys after heat treat
Solid carbide components — end mills, inserts, wear pads, cutting tools
Plasma-sprayed carbide overlay — oilfield and wear-resistant components that conventional machining cannot touch
No cutting force — safe on thin walls, fragile features, and delicate workpieces
Burr-free edges — spark erosion leaves a clean, ready surface

APPLICATIONS

Where It Ships

  • Keyways and splines in shafts and bores — tighter than milling can hold
  • Tight-tolerance slots in hardened valve and pump components
  • Precision splitting and sectioning with minimal material loss
  • Profile cuts in Inconel, Hastelloy, Ferralium, and other hard alloys
  • Features that cannot be produced by conventional milling or grinding

QA & DOCUMENTATION

What ships with every job

Wire EDM cuts any electrically conductive material — steel, stainless, nickel alloys, carbide, copper, and all tool steels. Hardness has no effect on cut quality. Kerf width is approximately 0.020". Tolerances to ±0.0002" are routinely achievable because there is no cutting force to deflect the workpiece.
