Electrical Discharge Machining (EDM) is a manufacturing process that shapes a workpiece by using sparks generated through electrical discharges. A dielectric fluid separates two electrodes across which a voltage is applied, creating a rapidly fluctuating periodic electrical discharge to machine the

Carbon felt, also known as carbon fiber felt, turns into graphite felt when heated to nearly 3,000 degrees under an oxygen-free environment. After being made into graphite fiber felt, its usable temperature can reach over 2,800 degrees. That is to say, graphite felt is more resistant to high tempera
