Automated Die-Sinking EDM Guarantees High Precision by Mastering Temperature Fluctuations

Like all of GF Machining Solutions' AgieCharmilles die-sinking EDM machines, the FORM X 400 features the Intelligent Speed Power Generator (ISPG), the world's most powerful die-sinking EDM generator. Users can achieve unprecedented quality and efficiency thanks to the machine series' discharge circuit, which provides spark erosion power modulation for high flexibility and maximum material removal. For example, the system optimizes micromachining processes so that fewer electrodes are needed to machine sharp internal corners.

Users of FORM X series machines benefit from advanced levels of logic, speed and safety thanks to the latest generation of the AC FORM human-machine interface (HMI) from GF Machining Solutions. The ergonomic AC FORM HMI is organized with a single menu level containing all icons in a logical, chronological order of use -- and dynamic contextual help is just a click away.

The FORM X series' software ensures greater reliability, improved machining efficiency and significantly less unproductive time for the highest level of precision and machine performance. The series' TECFORM EXPERT module allows the machine to quickly and safely produce the desired results. For further process optimization, industry-specific technologies free the machine operator from the task of adjusting the generator's parameters.

With its central database, the System 3R WSM keeps production running on the FORM X 400 with standardized procedures and manages the automation process, all while growing with users demands by making it easy to add new machines in the future. Integration is the key to unlocking the full potential of any manufacturing environment, and WSM streamlines this process.

WSM allows job lists to be interrupted so an urgent part can be machined; upon completion, the cell automatically returns to the list of jobs to be executed. Additionally, WSM helps eliminate the need to have all parts and electrodes 100 percent ready before executing a job. Machining can start while the parts and electrodes are being measured and loaded into the robot magazine, and WSM seamlessly updates the information about the running job as parts are loaded.

Specifically, for high-accuracy part processing, the FORM X 400 boasts a thermal control system that guarantees unmatched machining precision by using temperature-stable dielectric fluid to cool the machine's X, Y and Z-axis glass scales and the Z-axis ball screw.

Additionally, the machine body is thermally isolated from the high-speed Z axis, and all moving parts are fully disassociated from the loading and machining area, all of which ensures that temperature variations and particularly heavy or light workpieces cannot affect machining and measuring accuracy.
