146 MMS June 2017 mmsonline.com MODERN EQUIPMENT REVIEW Spotlight: EDM EDM Network offers Chmer EDM's six-axis AD5L EDM Drill/Mill, a high-speed EDM drilling machine that can also mill 3D diffuser shapes required for air cooling in jet engines and industrial gas turbine generators. The AD5L can be equipped for fully submerged operation or standard flushing. Also available are a 20-position rotary electrode changer and a guide changer to handle different electrode diameters in one setup. SIX-AXIS EDM DRILL ALSO MILLS 3D SHAPES series of wire EDMs. The series has a new digital power manager for improved cutting and accuracy, an HP AVR circuit for better accuracy with mul- tiple parts, and two options on cutting surface roughness: the WGPlus SKD-11 (0.3 micron Ra) and the WGPlus tungsten carbide (0.1 micron Ra). The company says that this series is ideal for those seeking a modern wire EDM with a user- friendly control interface. There are four models in this series. X, Y and Z axes measure 15.7" × 11.8" × 8.7" on the V400G Plus; 19.7" × 11.8" × 12.2" on the V500G Plus; 25.6" × 15.7" × 16.1" on the V650G Plus; and 31.5" × 19.7" × 13.8" on the V850G Plus. Other features include a Windows XP-based control; rigid, heavily-ribbed, high-grade Meeha- nite castings; a direct-couple drive system (no belts); electrolysis-free machining with Digital Power Manager technology; and intelligent servo- controlled wire threading technology.

BRASS COATING PROTECTS CARBIDE EDM PARTS FROM OXIDATION Seibu's EL coating, available from KGK Interna- tional, is de signed to prote ct carbide par ts, resulting in longer tool life and more parts pro- duced. Seibu's wire EDMs require a simple M code to be added to the CNC program in order The EDM's X-, Y- and Z-axis travels measure 500 × 300 × 350 mm, with an optional Z-a xis travel of 600 mm also available. The X and Y axes are driven by the Chmer linear motors using Panasonic drives with precision glass scales for positioning accuracy. Submersible A-B index tables are available from MMK, Yukiwa, Parkson, Hirschmann and others. Electrode diameters range from 0.2 to 6.0 mm. EDM Network Inc., call 888-289-3367 or visit edmnetwork.com.
