Wire EDM (Wire Electrical Discharge Machining) is a non-contact precision machining process designed for electrically conductive, hard-to-cut materials. Using a continuously fed fine wire and controlled electrical discharges, Wire EDM enables highly accurate cutting without introducing mechanical stress or distortion.
At EadeTech, Wire EDM is widely applied to titanium alloys, nickel-based superalloys, tungsten, molybdenum, and hardened steels, supporting aerospace, medical, electronics, and industrial customers worldwide.
Traditional CNC milling or turning often struggles with advanced alloys due to:
Extreme material hardness
Rapid tool wear
Heat accumulation
Thin-wall deformation
Wire EDM eliminates cutting force entirely, making it ideal for thin sections, intricate profiles, and tight tolerances, even in materials exceeding 50 HRC.
Max workpiece size: 800 × 600 × 400 mm
Wire diameter range: Ø0.10 – Ø0.30 mm
Minimum internal corner radius: 0.05 mm
Tolerance capability: ±0.002 – ±0.005 mm
Surface roughness: Ra 0.4 – 1.2 μm
| Parameter | Capability |
|---|---|
| Dimensional tolerance | ±0.002–0.005 mm |
| Straightness | ≤0.003 mm / 100 mm |
| Surface finish | Ra 0.4–1.2 μm |
| Repeatability | ±0.002 mm |
| Kerf width | 0.12–0.35 mm |
Wire EDM is particularly effective for materials that are difficult or inefficient to machine by conventional methods.
| Material | Typical Hardness | Application |
|---|---|---|
| Ti-6Al-4V | ~36 HRC | Aerospace structures |
| Inconel 718 | ~45 HRC | Turbine components |
| Tungsten | Very high | Thermal parts |
| Molybdenum | High | Electronics |
| Hardened tool steel | 50–65 HRC | Precision tooling |
Aerospace brackets and frames
Thin-wall titanium components
Precision slots and keyways
Medical device tooling
High-precision inserts
| Industry | Component | Key Benefit |
|---|---|---|
| Aerospace | Titanium brackets | Zero distortion |
| Medical | Surgical tooling | Burr-free edges |
| Electronics | Tungsten parts | Sharp profiles |
| Industrial | Superalloy inserts | High accuracy |
To achieve superior accuracy and surface quality, EadeTech uses a multi-pass EDM approach:
Rough cutting for shape definition
Semi-finish trimming for stability
Final finishing for tolerance and surface quality
| Pass Type | Purpose | Offset Range |
|---|---|---|
| Rough cut | Fast material removal | 0.01–0.03 mm |
| Trim cut | Dimensional control | 0.005–0.01 mm |
| Finish cut | Surface quality | ≤0.003 mm |
Every Wire EDM part is verified using:
Coordinate Measuring Machines (CMM)
Optical inspection for edge quality
Flatness and straightness measurement
Surface roughness testing
| Item | Method | Acceptance |
|---|---|---|
| Dimensions | CMM | ±0.002–0.005 mm |
| Edge quality | Microscope | No burrs |
| Flatness | CMM | ≤0.01 mm |
| Surface finish | Ra tester | As specified |
Proven experience in specialty metals
Excellent stability for thin and hard materials
Integrated CNC machining and finishing
Ideal for prototypes and small batch production
