Charmilles (Lincolnshire, IL) has developed the GammaTEC for its ROBOFORM 350 and 550 die sinking machines to meet the high quality and finish demand and time requirements in the mold manufacturing portion of the design process. During the design phase, consumer goods often undergo frequent modifications and must maintain or increase initial quality. Equally imperative is that its molds maintain an equally high standard of excellence. To uphold the high levels of mold manufacturing involves long hours of fine finishing with EDM followed by hand polishing. It is here in the polishing process that the risk of geometrical distortion is increased. Polishing also is a time consuming effort that is both expensive and not ideal for accessing in and around small details. This technology also maintains the surface quality of the molds and has approximately 30 percent less electrode wear—and it reduces time loss in the process of tool manufacturing. Not only is the need for hand polishing avoided in most cases, total tool manufacturing time also is compressed. In addition, this technology shortens the discharge ignition time; it results in an increase in frequency of erosive discharges, accelerates the EDM process and produces a homogeneous diffusion of spark energy. Machining with GammaTEC and standard EDM are both possible on the same machine.
