Die-sinking EDM

What is Die-sinking EDM?

Die-sinking electro-erosion, also known as sinker EDM or Die-sinking EDM, is a machining process to shape and form metal parts with high precision. It involves the use of electrical discharges, which materialize as sparks, to remove material from a workpiece.

A shaped electrode, often made of graphite or copper, will create a negative impression in the workpiece, usually consisting of a conductive material such as steel. The electrode and the workpiece are submerged in a dielectric fluid and a potential difference is applied between them. As the electrode approaches the workpiece, sparks jump across the gap, removing material from the workpiece and forming the desired shape.

This process is particularly useful for creating intricate and complex shapes in hard material that would be challenging or nearly impossible to achieve with traditional machining methods. It is widely used in the manufacturing of molds and dies, and for creating precision components in the aerospace and medical industries.
