Wire EDM uses a thin, electrically charged brass or molybdenum wire surrounded by deionized dielectric fluid to erode conductive materials with sub-micron accuracy regardless of hardness.
Engineering Specifications & Parameters
Wire Diameter
0.10 - 0.30 mm
Surface Roughness
Ra 0.2 to 0.8 μm
Hardness Capability
Up to 70+ HRC
Precision Tolerance
±0.002 mm (±0.00008 in)
Non-Contact Thermal Erosion
Because no mechanical cutting force is exerted on the workpiece, Wire EDM easily cuts hardened tool steels (60+ HRC), exotic superalloys, and fragile micro-structures.
Key Advantages
Zero Cutting Stress: No mechanical deflection or clamping distortion.
Sharp Internal Corners: Inner corner radii as small as 0.05 mm (0.002 in).
High Aspect Ratio: Deep vertical slots that end mills cannot reach.
Frequently Asked Questions
Can Wire EDM machine non-conductive materials like plastics or ceramics?
No, Wire EDM requires electrical conductivity to generate the spark erosion discharge. Non-conductive materials cannot be EDM-cut.
