Compact EDM for Small Shops Delivers Consistent Accuracy
GF Machining Solutions’ new compact Form E 350 machine is a die-sinking EDM solution for small shops.
GF Machining Solutions’ new compact Form E 350 machine is a die-sinking EDM solution for small shops. The machine boasts a sturdy C-axis construction and cross table, which combine with the cast iron frame to offer high stability and force reduction to help maintain a precise spark gap between the part and the electrode. According to the company, the machine delivers consistent accuracy regardless of part weight or dielectric volume. 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 system is said to excel at surface finishes and precision applications in any conductive material. It overcomes common process challenges for copper electrodes, including electrode wear induced by electrical discharge.
Designed for high efficiency on the shop floor, the machine features a programmable dielectric management system with a 270-L capacity integrated inside the machine cabinet. This system fills and empties the work tank without human intervention, keeping the machine in production. The tank is easy to access for routine maintenance.
The machine comes equipped with the user-friendly AC Form human-machine interface (HMI) based on Windows. It offers interactive graphical assistance to speed operator understanding. It provides simple descriptions of machining targets, automatic selection of optimal technology and dynamic parameters adaption.
With an X, Y and Z travel of 17.8" × 9.8" × 9.8" (350 × 250 × 250 mm), the system handles workpieces as large as 31.5" × 19.7" × 10.4" (800 × 500 × 265 mm.) It also has a four-position linear toolchanger and is automation-ready, easily paired with the System 3R WorkPartner 1+ robot to implement unattended night and weekend operation.
Additives, machine settings, workpiece materials and current technology are factors in avoiding common problems with unwanted rust and surface defects.
Electrical discharge machines, both wire and ram type, have undergone rapid improvements in capability, economical operation, speed and flexibility. New applications are continually emerging as shops discover the advantages of this process.
A new breed of power generators for wire EDMs has options for reducing, even eliminating, one of the unwanted side effects of this very versatile metalcutting process.
