The Electrical Discharge Machining (EDM) Workshop at SEDI Minna is a cutting-edge facility specializing in high-precision machining of hard metals and intricate components. EDM technology allows for non-contact material removal using controlled electrical discharges, making it ideal for manufacturing complex shapes, delicate parts, and ultra-hard materials that traditional machining cannot handle.

Our EDM workshop is equipped with advanced Wire EDM and Die-Sinking EDM machines, enabling ultra-precise metal cutting, cavity forming, and tool and die manufacturing. This capability is crucial for industries requiring extreme accuracy, such as aerospace, automotive, medical devices, and high-performance engineering applications.

Capabilities of Our Electrical Discharge Machining (EDM) Technology

Our EDM machines at SEDI Minna offer advanced precision machining capabilities, including:

1. Wire EDM (Wire Electrical Discharge Machining)

• Uses a thin, electrically charged wire to cut through hard metals and alloys.
• Precision cutting with tolerances as tight as ±0.002 mm.
• Ideal for creating intricate shapes, complex geometries, and fine details.
• No mechanical stress on the workpiece, preserving material integrity.

2. Die-Sinking EDM (Sinker EDM)

• Uses a custom-shaped electrode to erode material and form cavities.
• Ideal for mold-making, die fabrication, and intricate tool designs.
• Achieves deep, detailed engraving with minimal material distortion.
• Works effectively on hardened steel, tungsten carbide, and titanium.

3. Micro EDM (High-Precision Small Component Manufacturing)

• Creates microscopic features on metal components with extreme accuracy.
• Used for micro-tooling, delicate surgical instruments, and high-performance electronics.
• Produces burr-free surfaces and intricate designs with no post-processing required.

4. Hole Drilling EDM (Small Hole Drilling)

• Drills tiny, deep holes with high aspect ratios.
• Suitable for cooling holes in turbine blades, medical implants, and high-precision molds.
• Works on hard and conductive materials that conventional drilling cannot handle.

Advantages of EDM Over Traditional Machining
