Precision EDM
Wire-cut, sinker EDM, micro-hole EDM (via partner network)
EDM is ideal for high-hardness materials, complex internal contours, and deep narrow slots that conventional cutting can't reach. Through our long-standing partner network, we integrate EDM with our in-house CNC machining for a complete one-stop solution.
Typical projects include: mold lifter internal contours, go/no-go gauges, deep narrow slots, and micro-hole machining for fuel injectors. Wire EDM maintains ±0.002 mm accuracy on hardened steels — handling features that CNC milling cannot.
Equipment
- Wire-cut EDM
- Sinker EDM (Die-sinking)
- Micro-hole EDM
Applicable Parts
- Complex internal profiles (shapes inaccessible to milling)
- Hardened mold parts, stamping dies, gauges
- Deep narrow slots, precision tooth profiles
- Micro holes (nozzles, injectors, fluid-control parts)
Compatible Materials
- Hardened tool steel (SKD11, SKD61, SKH51)
- Cemented carbide (tungsten carbide types)
- High-carbon steel (SK3, SK4)
- Pre-hardened steel, stainless steel
- Other conductive materials
Specs & Tolerances
- Wire EDM tolerance: down to ±0.002 mm
- Sinker EDM surface finish: Ra 0.2 or better (fine pass)
- Micro-hole minimum diameter: depends on EDM conditions
- Material must be electrically conductive
