Sinker EDM vs. Wire EDM: Key Differences and Applications

Electrical Discharge Machining (EDM) uses controlled electrical sparks to shape metal parts. It has two main types: Wire EDM and Sinker (Ram) EDM. Both remove material without direct contact but serve different purposes. This resource explains the key differences between Wire EDM and Sinker EDM. It will help you choose the right method for your specific machining needs.

Everything You Need to Know About Sinker EDM Machining

Sinker EDM is a subtractive manufacturing process that removes material using electrical discharges. It uses a custom-shaped electrode that is lowered into a conductive workpiece while both are submerged in dielectric fluid. The electrode never touches the material. Instead, controlled sparks erode the surface to form precise cavities.
