lectrical Discharge Machining (EDM) is a precision machining process that utilizes electrical sparks to remove material from a workpiece. In EDM, a tool electrode and the workpiece are submerged in a dielectric fluid (usually oil or deionized water) but do not make direct physical contact. When an electrical voltage is applied between the tool and the workpiece, intense electrical discharges or sparks occur in the small gap between them. These sparks generate extremely high temperatures, melting or vaporizing small bits of material from both the tool and the workpiece. As the process continues, the material is gradually eroded, shaping the workpiece to the desired form. EDM is known for its ability to cut intricate shapes, very hard materials, and parts with tight tolerances, making it valuable in industries like aerospace, toolmaking, and mold production.
Wire EDM
Wire Electrical Discharge Machining (Wire EDM) is a specialized machining technique that employs a slender, electrically conductive wire as the tool electrode. This thin wire is submerged in a dielectric fluid, usually deionized water, which serves multiple purposes during the process, including cooling, debris removal, and providing a medium for electrical discharges to occur. In...
Sinker (or Ram) EDM
Sinker (or Ram) EDM is a specialized machining process used with electrically conductive materials, particularly metals. In this method, a solid, three-dimensional tool electrode (often made of graphite or copper) is employed. The workpiece and the tool electrode are submerged in a dielectric fluid, typically oil or deionized water. This fluid serves to cool the...
