Difference between wire cutting EDM and die sinking EDM machines

Wire cutting and die sinking EDMs are two different types of electrical discharge machining processes used in the metalworking industry.
Wire cutting EDM machines ("wire EDM" or "wire erosion machines") use a thin wire electrode to cut through a workpiece. The wire is made of a conductive material, such as brass or tungsten, and is usually around 0.1 to 0.3 mm in diameter guided by a series of pulleys and moves through the workpiece under the control of a computer program. This process is ideal for creating complex shapes, such as gears, without the need for extensive tooling.
Die sinking EDM machines ("sinker EDM" or "spark erosion machines") use a special electrode, usually made of graphite or copper, to create a cavity or impression in the workpiece. The electrode is lowered into the workpiece and a high-frequency electrical discharge is used to remove material from the surface of the workpiece. This process is ideal for creating molds and dies used in the manufacturing of metal parts.

How does wire cutting erosion work

Wire cutting erosion, also known as wire EDM (Electrical Discharge Machining), is a non-traditional machining process that uses an electrically charged wire to cut and shape metal parts.
The wire is typically made of brass or tungsten, and is connected to a power source. When the wire is brought close to the workpiece, an electrical discharge is generated between the wire and the workpiece, creating a spark that vaporizes the metal and creates a small crater.
The spark is then extinguished, and the wire moves a small distance away from the workpiece. This process is repeated thousands of times per second, creating a series of craters that eventually cut through the workpiece. The wire is constantly fed through the workpiece, creating a kerf or slot in the metal.
Wire cutting EDM machines are capable of producing very precise and complex shapes, and can be used on a variety of materials, including metals such as steel, aluminum, and copper, as well as some non-metallic materials. The process is ideal for creating parts that have intricate shapes or require very tight tolerances, as the wire can cut very fine details and produce very accurate dimensions.
Wire cutting EDM machines are widely used in industries such as aerospace, medical, and automotive, where precision and complexity are critical to the final product.
