Elektritöötlus

Elektritöötlus, also known as electrical discharge machining (EDM), is a manufacturing process where a shaped tool, electrodes, or workpiece is subjected to electrical discharges. This process utilizes thermal energy generated by electrical discharges to remove material from a workpiece. The workpiece is submerged in a dielectric fluid, which is typically deionized water or oil, and acts as an insulator. An electrical current is then applied between the tool electrode and the workpiece, creating sparks. These sparks erode the workpiece material in a controlled manner, shaping it according to the electrode's design. EDM is highly effective for machining hard materials and complex shapes that are difficult to produce with conventional machining methods. It is commonly used in industries such as aerospace, automotive, and medical device manufacturing for creating intricate components, molds, and dies. The precision of EDM allows for very tight tolerances and excellent surface finishes. Different types of EDM exist, including wire EDM, die-sinking EDM, and hole drilling EDM, each suited for specific applications.
