What is the application of EDM machine
EDM machine has an extensive range of applications. Because the EDM process can cut very small pieces, it is often an ideal choice for the production of small, highly detailed items that would typically be too delicate for other machining options. Additionally, the process is cost-effective for low quantity projects and can prove to be beneficial in prototype manufacturing, even if the actual project is carried out by different means.
It is important to remember that in wire-cut EDM, the wire is continuously moving, and not to be reused. As a result, the copper, brass, or other metallic wire can be kilometers long, adding to the cost. Moreover, while the process uses no force and thus does not cause burrs and can be used on delicate items, the possibility of thermal stress is undoubtedly present

EDM is used mainly by the mold-making, tool, and die industries. It is also becoming a popular means of machining prototype and production parts, especially in the automobile, aerospace, and electronics industries because production quantities are relatively low. Electrical discharge machining also creates dies for producing jewelry and badges, or blanking and piercing.
Manufacturers sometimes use EDM machines for the specific purpose of removing broken tools workpieces. This process is termed "metal disintegration machining" or MDM. It removes only the center of the tap, bolt, or stud and leaves the hole intact so the part can be reclaimed.
