GF AgieCharmilles new FORM 2000 VHP and FORM 3000 VHP machines bring very high precision in die-sinking electrical discharge machining (EDM) by mastering temperature fluctuations. The result is superbly precise machining of complex applications where there is no room for error.
In engineering the FORM 2000 VHP and FORM 3000 VHP, GF AgieCharmilles Research and Development took into account the affects of temperature fluctuation on precision and mastered those variations, which can be related to the machining environment or the machine itself. The new machines’ thermo control system guarantees unmatched precision under even less-than-ideal workshop conditions.
The sophisticated and unique thermo control system compensates for temperature variations by using temperature-stable dielectric to cool the X, Y and Z glass scales, as well as the Z axis ball screw. In assembly, the machine body is thermally isolated from the high-speed Z axis, which is cooled with dielectric fluid.
Whether you’re machining a single cavity or a multi-cavity mold for serial production of small parts, like lens holding pieces for electronic components, the FORM 2000 VHP and FORM 3000 VHP represent maximum positioning accuracy. In addition to offering optimal global thermostabilization, the machines themselves are assembled with highest accuracy and under strict manufacturing conditions and tested with a laser interferometer during the final steps of production to ensure perfect 3D positioning.
Latest technologies on board
Like all GF AgieCharmilles die-sinking EDM machines, the FORM 2000 VHP and FORM 3000 VHP feature the Intelligent Power Generator (IPG), one of the world’s most powerful gene-rators for die-sinking EDM. With integrated quality-enhancing and cost-saving intelligence, TECFORM ensures that the EDM process is continuously optimized with each pulse to significantly reduce electrode wear or even reach the finest finishes. The embedded TECFORM module allows the FORM 2000 VHP and FORM 3000 VHP to quickly and safely achieve the best performance and produce the desired result. Segment-dedicated techno-logy eliminates the need for the operator to adjust the generator’s parameters.
The machines’ software manages job preparation and setup and offers a range of machining strategies to ensure highest precision and performance. Process control takes a fraction of a second and produces an extremely homogeneous surface finish. In combination, these features yield greater reliability, improved machining efficiency and significantly less unpro-ductive time.
Moreover, the FORM 2000 VHP and FORM 3000 VHP feature GF AgieCharmilles’ new and ergonomic AC FORM human-machine interface (HMI) for a new level of logic, speed and safety. Developed on the basis of a study with numerous customers to streamline the mold making process, AC FORM HMI is organized on one menu level where all icons are arranged logically and in chronological order of use, and dynamic contextual help is always just a click away.
On board the new machines are GF AgieCharmilles’ breakthrough iQ (innovation + quality) technology ensuring absolute pulse efficiency to eliminate wear and save on expensive material. In both copper and graphite, iQ technology captures debris and exploits it as a protective and “healing” layer on the electrode. Furthermore, iQ makes it possible to reduce the number of electrodes consumed by as much as two thirds while at the same time dramatically decreasing erosion time. That means savings on both electrodes and greater time, and the result is greater profit.
