Precision machining with electrical discharge technology
Wire Electrical Discharge Machining (Wire EDM) uses a thin electrically charged wire to cut conductive materials with extremely high precision. The wire acts as an electrode, and electrical sparks erode the material along the programmed path.
| Parameter | Typical Range | Impact |
|---|---|---|
| Wire Diameter | 0.1-0.3 mm | Kerf width, detail resolution |
| Wire Material | Brass, coated brass, molybdenum | Cut speed, surface finish |
| Pulse ON Time | 0.5-50 us | Material removal rate |
| Peak Current | 5-50 A | Cutting speed, surface quality |
| Dielectric Flow | 5-20 L/min | Flushing efficiency, stability |
Wire EDM can achieve positional accuracy of ±0.002 mm and surface finish down to Ra 0.2 um. Multiple skim passes improve finish but increase cycle time.
