What is EDM
Electrical discharge machining, or EDM for short, is a highly accurate machining process during which sparks, or electrical discharges, shape a workpiece by removing material.
EDM is perfect for applications that require the creation of intricate details or complex geometries such as in the fields of aerospace, automotive, defense, extrusion, electronics, food and beverage, medicine, and stamping.
Another aspect of of EDM is metal disintegration machining. During metal disintegration machining, manufacturers use electrical discharge machines to disintegrate broken tool parts stuck inside workpieces. Examples of these tool parts include studs, taps, drill bits, and bolts. By removing them from the center of a workpiece, manufacturers can recycle or reclaim the workpiece material.
Benefits of the EDM Machining Process
Electrical discharge machining supplies a wide variety of advantages to both manufacturers and customers.
- Electrical discharge machining creates products and parts with highly accurate markings, angles, cuts, etc.
- EDM machines can machine even the smallest parts or smallest lines. The complex shapes that manufacturers can make with EDM tooling would be difficult or impossible with traditional tooling.
- EDM machines can accurately cut even the hardest of metals without preheating them.
- EDM does not use impact or abrasion to achieve its goals. In fact, the EDM tool never makes physical contact with the part being machined. This is a significant advantage. Because the EDM tool never makes physical contact with the part being machined, that part is not deformed, nor does it sustain heat damage or imperfections like burrs.
- With EDM, creates excellent surface finish qualities.
Products Produced with Saturn’s EDM Services
Using electrical discharge machining, manufacturers produce molds, tools, and dies for the forming, casting, and forging of products and parts like plastic molds, compressor blades, various engine parts, jewelry, badges, coinage, plastic mold production, compressor blade production, and the production of other engine parts. With EDM, manufacturers also make prototypes and sample parts for customers in auto, aerospace, and electronics.
Design Considerations
EDM machines can cut through most any material, metal, or otherwise. Examples of materials they work with include aluminum, bronze, cobalt, copper, gold, lead, nickel, silicon, stainless steel, titanium, and tungsten.
When deciding on what tool or tools are best for their application, manufacturers consider variables such as the intended shape and size of the end product, and the work piece material (which must match with the electrode material or tool material/design in order to work properly).

Almost all metallic and electrically conductive materials can be machined using the EDM process. Most common are aluminum, alloy and stainless steels, nickel based alloys, titanium, copper tungsten and tungsten carbide.
