wirecutting

Wirecutting, also known as wire erosion or wire EDM, is a non-traditional machining process that uses a thin electrically conductive wire to cut intricate shapes and profiles in electrically conductive materials. The process relies on a series of controlled electrical sparks that occur between the wire electrode and the workpiece. These sparks erode a small amount of material from the workpiece, gradually cutting through it. The wire, typically made of brass, copper, or zinc-coated brass, is continuously fed from a spool and travels through the workpiece, guided by a precision control system. A dielectric fluid, usually deionized water, is sprayed onto the cutting area to cool the workpiece, flush away eroded particles, and provide an insulating medium that facilitates the spark erosion process. Wirecutting is known for its ability to produce very precise and complex shapes, with excellent surface finish and tight tolerances, making it suitable for applications in industries such as aerospace, medical devices, and tool and die manufacturing. It can cut materials that are too hard or brittle for conventional machining methods.
