4 times less electrode wear with graphite electrodes! The new EDAF Series sinker-EDM comes with Makino's popular H.E.A.T. technology, available until now in the U series wire EDM machines. . The new EDAF comes with improved feed rates up to 5,000 mm/min in the X- and Y-axes. Another feature, HS-Rib, gives the Z-axis a jump speed of 20m/min, a 31% increase over the current model. - New more powerful H.E.A.T. generator (up from 40A to 80A peak current in standard, reducing power consumption by 44%) - Faster feedrates - New flushing control
