All about Electrical Discharge Machining

As per Technavio, the global electrical discharge machine market is anticipated to grow at a steady rate and will post a CAGR of 8% during 2017-2021. This growth for the global electrical discharge machine market is driven by the increasing production rate of light vehicles. Although the origin of Electrical Discharge Machining (EDM) goes back to 1770, this technology has rapidly earned its place alongside milling and grinding equipment as a proactive, mainstream technology. The reason behind its rise is the ability of the EDM process to machine complex shapes in very hard metals. Hence, the most common uses of EDM are in machining dies, tools, and molds made of hardened steel, tungsten carbide, high-speed steel, and other workpiece materials that are difficult to machine by “traditional” methods.
