GF Machining Solutions’ Form P 350 die sinking EDM includes precision-enhancing features and integrated technologies that are said to enhance productivity and profitability.

A compact C-axis construction, fixed table and cast iron frame offer stability and force reduction to maintain a precise spark gap between the part and electrode. Regardless of part weight or dielectric volume, the machine is said to deliver consistent accuracy and surface finishes of Ra 0.1 micron. Integrated glass scales preserve repeatability and eliminate the need for recalibration and errors due to backlash and wear.

The machine includes the company’s intelligent power generator and Tecform module, which optimizes each pulse, reducing electrode wear and producing high-quality surface finishes. Segment-dedicated technology eliminates the need to adjust the generator’s parameters. These features yield reliability, improve efficiency and reduce unproductive time.

The company’s iQ (Innovation and Quality) technologies control the erosion of graphite and copper electrodes and reduce costs. Real-time spark characteristic analysis and setting adjustment for pulse efficiency ensure wear-free spark erosion, precision, efficiency and greater control over the cost of the electrode.

The console’s AC Form human-machine interface (HMI) is based on Windows. Interactive graphics illustrate operations such as measurement and machining cycles for ease of use. It provides descriptions of machining targets, automatic selection of optimal technology and dynamic parameter adaption.

The machine comes standard with a four-position linear toolchanger for System 3R macro tooling. An optional rotary toolchanger can increase the number of electrodes to 160. The EDM can also be paired with the System 3R WorkPartner 1+ robot for unattended night and weekend operation.

With X-, Y- and Z-axis travels of 17.8" × 9.8" × 11.8" (350 × 250 × 300 mm), the machine accommodates workpieces as large as 27.6" × 18.1" × 10.8" (700 × 460 × 275 mm).
