What is the main function of Sinker EDM?

The main function of Sinker EDM (Electrical Discharge Machining) is to produce three-dimensional shapes in workpieces. This process utilizes controlled electrical discharges to remove material from the workpiece, allowing for intricate and complex geometries that may be challenging to achieve with traditional machining methods. The electrode, usually made from a conductive material, is shaped in the desired form, and as it discharges energy into the workpiece, it removes material in the exact shape of the electrode, thereby creating the desired three-dimensional contour.

This capability is particularly useful in the production of molds and dies, where precision and detail are crucial. Sinker EDM excels in machining hard materials and is often employed in situations where traditional methods would face limitations due to the complexity of the design.

Creating flat surfaces and machining external profiles are more characteristic of other machining processes rather than Sinker EDM, which focuses on contouring the material to replicate the electrode's shape. Similarly, increasing the speed of material removal is not the primary function; rather, Sinker EDM emphasizes precision and the ability to produce detailed, complex shapes over speed.
