CNC Machined Parts(EDM) is a non-traditional machining process used to remove material from conductive materials by using electrical discharges or sparks.The process works by creating an electrical arc or spark between a tool electrode and the workpiece. The spark generates heat, which melts or vaporizes the material, and a small amount of material is removed from the workpiece. The tool electrode is usually made of a conductive material such as copper or graphite, and the workpiece is submerged in a dielectric fluid such as oil or deionized water, which helps to cool the machining area and conduct the electrical current.

There are two main types of EDM: wire EDM and sinker EDM. In wire EDM, a thin wire is used as the tool electrode to cut the workpiece into a desired shape, while in sinker EDM, a shaped electrode is used to create a cavity or shape in the workpiece. Both types of EDM are commonly used in manufacturing industries for producing complex shapes and features in parts that are difficult or impossible to machine using traditional methods.

EDM is particularly useful for working with hard, brittle materials such as carbides, ceramics, and exotic alloys, which can be difficult to machine using conventional cutting methods. It is also useful for producing intricate and delicate parts, as well as for creating small holes and slots with high aspect ratios. Edm Mold Parts is widely used in aerospace, automotive, medical, and electronics industries for producing molds, dies, and other complex parts.

Electrical Discharge Machining (EDM) is a non-traditional machining process used to shape and remove material from conductive materials, such as metals and alloys, using electrical discharges or sparks.

The EDM process involves creating an electrical arc or spark between a tool (electrode) and the workpiece, which erodes the material from the workpiece to create the desired shape. The tool is usually made of a conductive material such as copper or graphite, and the workpiece is submerged in a dielectric fluid such as oil or deionized water to help conduct the electrical current and cool the machining area.
