MMS JUNE 2018 192 JEDD COLE | EDITOR | Modern Equipment Review EDM SPOTLIGHT Wire EDMs Handle Extra-Large Workpieces Sodick has released two models of wire EDMs, the ALN800G and ALN800GH. These machines are designed to accommodate extra-large work, with X-, Y- and Z-axis travels ranging to 31.5" × 23.6" × 31.5", respectively. The generator and control are said to improve accuracy and speed on large parts. Despite its size, the ALN800G offers a three-sided automatic drop tank for easy setup, even with a crane. Likewise, the high-column ALN800GH offers a Z height of 31.5" (800 mm). Both machines provide rigid linear motor drives for friction-free machining as well as a ceramic workspace capable of damping thermal distortion. | Sodick Inc. | 847-310-9000 | EDM's Optimized Pulses Reduce Electrode Wear GF Machining Solutions' Form P 350 die sinking EDM includes precision-enhancing features and integrated technologies that are said to improve productivity and profitability. A compact C-axis construction, fixed table and cast iron frame offer stability and force reduction to main- tain a precise spark gap between the part and elec- trode. Regardless of part weight or dielectric volume, the machine is said to deliver consistent accuracy and surface finishes of 0.1 µm Ra. Integrated glass scales preserve repeatability and eliminate the need for recalibration. 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 tech- nology eliminates the need to adjust the generator's parameters. These features yield reliability, improve efficiency and reduce unproductive time. The company's innovation and quality (iQ) technol- ogies control the erosion of graphite and copper elec- trodes 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. | GF Machining Solutions LLC | 800-282-1336
