What Is Electrical Discharge Machining?
Electrical Discharge Machining (EDM) also known as spark machining, spark eroding, die sinking, wire burning, or wire erosion, is a metal fabrication process that shapes materials using electrical discharges (sparks).
EDM is particularly useful for machining hard materials and creating complex shapes that are difficult or impossible to achieve with traditional machining methods.

Types of EDM Machining
There are different types of EDM machining techniques, and each type of EDM machining has its strengths and applications.
Wire EDM
Process: Use thin, continuously moving wire as the electrode to cut through the workpiece.
Application: Ideal for cutting intricate shapes, thin-walled parts, and tight tolerances.
Advantages: High precision, ability to cut hard materials, and no tool wear.
Sink or Ram EDM
Process: Uses a shaped electrode submerged in a dielectric fluid and moves towards the workpiece to erode the material.
Application: Suitable for deep cavities, complex shapes, and mold making.
Advantages: Can machine hard materials, high accuracy, and no mechanical contact between tool and workpiece.
Small Hole EDM
Process: Specialized for drilling small holes, typically using a small-diameter electrode.
Application: Used for cooling channels, nozzles, and other small feature machining.
Advantages: High precision and capable of drilling very small holes.
Key Features of EDM Machining
Non-Contact Machining
The workpiece is not physically touched by the tool, reducing stress and deformation.
High Precision
Capable of achieving very fine tolerances, often within ±0.0001″ (±0.0025 mm).
Versatility
Can machine a wide range of materials, including hardened steels, carbides, and superalloys.
Complex Shapes
Ideal for machining intricate and complex shapes that are difficult to achieve with traditional methods.
Applications of EDM Machining
Mold Making
Used extensively in the production of molds for injection molding, die casting, and other forming processes.
Aerospace
For machining complex parts with tight tolerances, such as turbine blades, engine components, and fuel system parts.
Medical Devices
Use in the manufacturing of precise components like surgical instruments, implants, and medical devices.
Semiconductor Industry
Used to create microstructures and precise features in semiconductor wafers and other components.
One-stop Surface Finishing
Improve your part’s performance by selecting high-quality surface finishes that enhance the roughness, hardness, chemical resistance, and cosmetic features of your finished component.
