Used electrical discharge machines / wire erosion machines for sale (4)

Electrical Discharge Machines (EDM), also known as wire erosion machines, are a type of manufacturing equipment used in the process of machining materials through the erosive effects of electrical discharge. This process involves the creation of sparks that erode the material into the desired shape.

Types of EDM

There are primarily two types of EDM machines:

• Wire EDM: Utilizes a thin wire as an electrode to cut complex shapes and delicate patterns into hard metals. The wire is continuously fed from a spool through the workpiece while being submerged in deionized water, which acts as a coolant and flushes away particles.
• Sinker EDM: Also known as ram EDM, this type uses a custom-shaped electrode that sinks into the workpiece to create shapes with intricate interiors, without requiring a through-cut.

Applications of EDM

EDM machines are commonly used in the production of tools and dies, and in the manufacture of complex aerospace and automotive components among other precision parts. These machines are preferred for handling hard materials, particularly those that are difficult to machine with traditional techniques.
