Like all EDM machines, the die sinking EDM machine works according to the principle of spark erosion. The special feature of this EDM machine is the shape of its electrode, which represents a negative image of the contour to be created on the workpiece. This is achieved by contactless melting and evaporating in the dielectric fluid. Since die sinking EDM machines are equipped with CNC control and a freely movable 5-axis head, dies, matrices, casting moulds and similar can be produced with the highest quality. At Surplex you will find used die sinking and wire EDM machines from AGIE CHARMILLES (Roboform/Agietron), EROWA, INGERSOLL, NASSOVIA, etc.
