Graphite electrodes

In many cases, the injection mold production process requires EDM treatment with the use of copper or graphite electrodes. Copper is a material that is known and widely used. However, more and more often it is displaced by isostatically pressed graphite due to its advantages. The use of graphite electrodes allows to significantly reduce the cost of producing the tool due to the shorter processing time of graphite, a smaller number of electrodes necessary to create the mold and, consequently, a shorter drilling process. Graphite processing is easy, fast and pleasant, but only on specially adapted machines. We provide our electrode milling services on CHMER HE65GT and OPS Ingersoll 600 machines, which are characterized by high machining accuracy and spindle speed up to 30 thousand. revolutions / min. We use the EROWA and 3R fastening system. We work on the basis of 2D and 3D documentation.
