The die sinking EDM machine is distinguished from wire EDM by the fact that both the workpiece and the tool, consisting of an electrode, are immersed in a tank submerged... by a dielectric fluid. Between the two, a series of electrical discharges are triggered that cause the erosion of the workpiece. The shape of the piece to be obtained is obtained in a complementary manner to that of the electrode. The machine then works in negative on the metal piece by using a three-dimensional male electrode. There is never any physical contact between the electrode tool and the workpiece. EDM, in general, is a very popular type of machining in the metalworking industry because it is possible to machine both hard and soft metals with excellent precision. At the same time, with this method it is possible to obtain complex shapes without having to resort to subsequent mechanical machining with other machines.
