GF Machining AgieCharmilles FORM F 450

The AgieCharmilles FORM F 450 is the middle size of GF Machining Solutions' FORM F series, a die-sinking EDM sold as a base machine that can be upgraded later. It has 450 x 300 x 350 mm of X, Y and Z travel, a 600 l dielectric capacity, and takes workpieces up to 820 x 540 x 270 mm and 800 kg. Best surface finish is 0.4 μm, with 0.10 μm as an option.

That split between standard and optional runs through the whole machine. The ISPG generator comes in a standard 40 A configuration and can be expanded to 80 A for higher erosion rates. GF sells Performance, Advanced Materials, Tooling and Precision Technology packages that add machining power, surface quality and application technologies to an installed machine, so a shop can start with the base specification and buy capability when the work calls for it. Automation is optional too: a four-position linear tool changer, an 18-position rotary tool changer or a left-side automation interface.

What comes with the series is the process control. iGAP manages the lateral spark gap, TECFORM sets parameters for graphite roughing and copper finishing, and an application database covers common cavity geometries and materials. High-resolution glass scales and encoder motors provide the axis feedback, and the AC FORM HMI adds guided workflows and measurement cycles. Econowatt lowers power draw when idle.

One figure needs attention: the electrode weight limit is 10 kg, against 50 kg on the AgieCharmilles FORM X 400. Large graphite electrodes for deep cavities can exceed that. The machine weighs 2940 kg without dielectric in a 2104 x 2022 x 2808 mm footprint.
