EDM Network will exhibit 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.

The EDM’s X-, Y- and Z-axis travels measure 500 × 300 × 350 mm, with an optional Z-axis travel of 600 mm. 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.
