Makino introduced the Ram EDM machinery, the EDAF Series. It is designed for manufacturing in uncontrolled thermal environments and long hours of unattended burning. EDAF-series machines are also equipped with a servo system for rapid response to signals from the spark gap monitoring circuits, enabling cycle time reductions of 10 to 20 percent in burns common to today’s shop applications.

The EDAF series features two models, the EDAF2 and EDAF3. The sizes of the EDAF2 is 53.2” x 95.5” x 98.4” and the EDAF3 is 59.1” x 102.4” x 100.8”. The EDAF2 has X-, Y-, and Z-axis travels of 13.8”, 9.8”, 9.8” and the EDAF3 has 17.7”, 13.8”, 13.8”. The EDAF2 provides worktable dimensions of 21.7” x 13.8” with a payload of 1,102 lb, while the EDAF3 offers table dimensions of 27.8” x 19.7” with a maximum payload of 1,764 lb.
