GF Machining Solutions’s new compact Form E 350 machine is a suitable die sinking EDM solution for small shops. The Form E 350 has sturdy C-axis construction, a cross table and a cast-iron frame for stability and force reduction, which helps maintain a precise spark gap between the part and the electrode. GF Machining Solutions says that 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. The Form E 350 also eliminates errors from backlash and wear.

The machine features a programmable dielectric management system with a 270-liter capacity integrated inside the machine cabinet. This system fills and empties the work tank without human intervention to keep the machine in production. The Form E 350 also comes with the Intelligent Speed Power Generator (ISPG) to provide quality surface finishes and precision applications in any conductive material. The generator improves machining speeds by 40 percent and reduces corner wear by 50 percent.

GF Machining says that the machine console comes equipped with a user-friendly, AC Form 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. The interface 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" (350 x 250 x 250 mm), the Form E 350 handles workpieces ranging to 31.5" x 19.7" x 10.4" (800 x 500 x 265 mm). 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.
