An electrical discharge machining (EDM) machine is a machining device that uses pulsed current to generate a discharge between the workpiece and an electrode, thereby removing material. It is suitable for hard metals, complex-shaped parts, and workpieces that are difficult to process using traditional cutting methods. The equipment uses a non-contact discharge machining method, is not limited by material hardness, and can process intricate structures, deep-cavity molds, and high-precision parts. During machining, the workpiece experiences minimal stress, and the heat-affected zone is small, making it easier to maintain machining accuracy and surface quality. EDM machines are commonly used in mold manufacturing, machining, and the electronics industry, providing reliable machining solutions for the manufacture of complex parts.
