Medium-speed wire EDM is a type of wire cutting machine with an electrode wire (referred to as the electrode) that moves continuously to erode metal and shape workpieces through pulsed spark discharges. Its processing quality falls between two extremes, hence the name "medium-speed." Essentially, medium-speed wire EDM is an upgraded version of high-speed wire EDM, which can be understood as a high-speed wire EDM capable of multiple cuts, yet it does not slow down the cutting speed compared to high-speed wire EDM; in fact, it's faster. The cutting speed is only reduced during multiple cutting processes to achieve the cutting effect, at which point the average efficiency is calculated, not the peak efficiency. Moreover, the quality of the processed workpiece tends to approach that of slow-speed wire EDM. The wire speed is automatically controlled by the system and can be adjusted as needed.
