Charmilles Gamma Tec

The Charmilles 550w/GAMMA TEC CNC is the normal conventional EDM machine that everyone is used to, but with the capabilities of polishing. The Charmilles 550 will give you a RMS finish of 4.9 with a copper electrode and a 12 with a graphite electrode. This is half of an aluminum mold and the electrode that was used in Northeast’s Charmilles 550 Gamma Tech to get the customer’s required 12-16 finish. This machine has the capabilities to give you a perfect mirror finish, and will make hand polishing a thing of the past.           This is another example of an aluminum mold. Achieves extremely high quality surface finishes, down to CH 6/Ra 0.2µm Provides significant time savings through reduction or elimination of hand polishing of parts Maintains high geometrical respect of shapes and details Increases number of parts per electrode due to 30% reduction in electrode wear GammaTEC and standard EDM achievable on the same machine
