FORM E 350 die-sinking EDM

Lincolnshire, Illinois – GF Machining Solutions’ compact FORM E 350 machine is a die sinking EDM solution for small shops. Even with its small footprint, the machine still boasts several design and performance features that enhance a shop’s competitive advantage.

A sturdy C-axis construction, cross table, and cast-iron frame offer high stability and force reduction, which helps maintain a precise spark gap between the part and the electrode. Regardless of part weight or dielectric volume, the machine delivers consistent accuracy. Integrated glass scales preserve long-term, repeatability and eliminate the need for recalibration as well as any errors found in traditional screw systems due to backlash and wear.

The latest-generation Intelligent Speed Power Generator (ISPG) on the FORM E 350 excels at superior surface finishes and precision applications in any conductive material. It overcomes common process challenges for copper electrodes, including electrode wear induced by electrical discharge. ISPG improves machining speeds by 40% and reduces corner wear by 50%.

Designed for high efficiency on the shop floor, the machine features a programmable dielectric management system with a 270L capacity integrated inside the machine cabinet. This system fills and empties the work tank without human intervention to keep the machine in production and is easy to access for routine maintenance.

The machine console comes equipped with the user-friendly AC FORM HMI (human machine interface) that is based on a standard Windows platform and offers interactive graphical assistance so that all operations, such as measurement and machining cycles, are illustrated by graphics/icons for fast operator understanding and ease of use. It provides simple descriptions of machining targets, automatic selection of optimal technology, and dynamic parameters adaption.

With an X/Y/Z travel of 17.8" x 9.8" x 9.8" (350mm x 250mm x 250mm), the FORM E 350 handles workpieces up to 31.5" x 19.7" x 10.4" (800mm x 500mm x 265mm.) It also has a four-position linear tool changer.

The FORM E 350 is automation ready and can easily be paired with the System 3R WorkPartner 1+ robot to implement unattended night and weekend operation.
