We also offer the service of die-sinking EDM.
In die-sinking EDM, the workpiece is in deionized water or non-conductive oil. While the machine head with the electrode – the tool – performs a movement in the z-axis, the table moves in the x- and y-axis. The electrode (cathode) is made of copper or graphite. The electrode is slightly smaller than the anode because the spark jumps through the dielectric as the cathode approaches the anode.
In sink erosion, the negative shape of the electrode creates a positive imprint in the electrically conductive workpiece. No voltage is created in the workpiece, but a high surface finish is left. The material is removed by evaporation or melting. A gas bubble created in the dielectric transports the removed material away and the dielectric is constantly filtered. In order to be able to machine several batches on the workpiece, there are so-called CNC-controlled machines for the die-sinking EDM process.
Die-sinking EDM is also used as a preparation for wire EDM. Die-sinking EDM creates the starting hole in steel that is already hard. The EDM wire is then threaded into this hole.
Benefit from our many years of experience. With us, customers get everything from a single source. With high-quality and modern technology and a top-equipped machine park, we realize your wishes quickly and environmentally friendly.
Die-sinking EDM offers several advantages over other manufacturing processes. The workpiece is precisely machined, resulting in a clean surface structure and high quality. The process is also suitable for the most complex contours. Moreover, only low tool costs have to be incurred for die-sinking EDM. All electrically conductive materials can be machined. Sharp-edged geometries can be realized with die-sinking EDM even at great depths.
