With an eye on the ever-changing world of consumer goods, automotive components and household and industrial appliance design, Charmilles developed GammaTEC for its ROBOFORM 350 and 550 machines. The creation enabled the company 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 its 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 is also a time consuming effort that is both expensive and not ideal for accessing in and around small details. GammaTEC, with its many patents, maintains the surface quality of the molds and has approximately 30% less electrode wear. GammaTEC also 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 is also compressed. “The GammaTEC solution combines optimization of the dielectric system with enhancements of technology and a specific pre-mixed additive, GammaMIX 50,” said Gisbert Ledvon, marketing manager, Charmilles. “GammaTEC is designed to focus on high performance in die sinking EDM and to assure repeatability on parts coming out of the work tank.” The GammaTEC 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.
