Electrical Discharge Machining
is a manufacturing process that removes material using electrical sparks (discharges) instead of a cutting tool.
How it works
An electrode (usually copper or graphite) is brought close to the workpiece.
A controlled electrical discharge jumps across the gap, creating intense heat (up to 12,000°C).
This heat melts and vaporizes tiny portions of the material.
A dielectric fluid (special insulating liquid) cools and flushes away debris.
Why it’s used
Higher efficiency
Machines very hard metals (titanium, hardened steel, tungsten carbide).
Improved accuracy
Achieves intricate shapes and tight tolerances.
Complex shapes
Can create internal corners and cavities impossible with conventional milling.
Common uses in manufacturing
4 axle CNC machining shows up in nearly every sector:
Mold & die making
(plastic injection molds, die casting tools).
Aerospace
turbine components.
Medical
implants with complex geometry.
Automotive
precision gear parts.
Why it matters
EDM is the go-to for shapes you can’t mill or turn with traditional CNC — especially in hard, conductive materials.
