Electrical Discharge Machining
Electrical Discharge Machining (EDM)
The EDM Process
At Aero Manufacturing we use a process known as Sinker Electrical Discharge Machining. First discovered in the early 1940s, this method is frequently used in tool and die applications to create intricate shapes and challenging parts.
EDM processes present several advantages for custom metal fabrication. When details and precision matter, the EDM provides very precise cuts with tolerances as low as +/- .0005. Additionally, complex shapes and configurations and very delicate, small, or fragile parts are easier to achieve with EDM than traditional machining.
Occasionally, projects require exotic or specialized materials. EDM processes are recommended for cutting extremely hard materials to create precision components. On a single cutting axis, Aero Manufacturing’s sinker EDM works with a wide variety of materials, including:
- Alloy Steels
- Cobalt
- Nickel
- Stainless Steel
- Inconel
- Superalloys
EDM also produces a final product without burrs which requires little to no polishing, reducing post-production steps and saving time.
