Understanding Electrical Discharge Machining (EDM)

What is EDM?

Electrical Discharge Machining is a manufacturing process that uses electrical discharges to shape materials.
It is particularly effective for hard metals and complex shapes that are difficult to achieve with traditional machining.
EDM operates by creating a series of rapid electrical sparks between an electrode and the workpiece.
These sparks erode the material, gradually forming the desired shape with high precision.

Types of EDM

There are primarily two types of EDM: Sinker EDM and Wire EDM.
Sinker EDM involves the use of custom-shaped electrodes to create cavities or intricate patterns.
Wire EDM, on the other hand, uses a continuously moving wire as the electrode, ideal for cutting complex contours and fine details.
Both types offer distinct advantages depending on the application and material requirements.
