Makino's latest Ram EDM machinery, the new EDAF Series, features a new mechanical design for increased rigidity and reduced thermal distortion.

The EDAF-series is ideal for manufacturers facing uncontrolled thermal environments and long hours of unattended burning.

EDAF-series machines are also equipped with an improved servo system for rapid response to signals from the spark gap monitoring circuits, enabling cycle time reductions of 10-20 percent in burns common to today's job shop applications.

There are two models in the series: the EDAF2 and EDAF3.

EDAF2: 1.4 m x 2.4 m x 2.5 m (53.2 in. x 95.5 in. x 98.4 in.) with X, Y, and Z axis travels of 0.4 m x 0.2 m x 0.2 m (13.8 in., 9.8 in., and 9.8 in.). This model provides worktable dimensions of 0.5 m x 0.2 m (21.7 in. x 13.8 in.) with a payload of 449 kg (1102 lb.).

EDAF3: 1.5 m x 2.6 m x 2.5 m (59.1 in. x 102.4 in. x 100.8 in.) with X, Y, and Z axis travels of 0.4 m x 0.4 m x 0.4 m (17.7 in., 13.8 in. and 13.8 in.). Worktable dimensions on this model are 0.2 m x 0.5 m (7.8 in. x 19.7 in.) with a maximum payload of 800 kg (1764 lb.).

Reliable, Worry-Free Unattended Burning

The EDAF-series comes equipped with new spark gap monitoring and arc prevention technology, ArcFree, which helps prevent destructive DC arcs that typically lead to time-consuming clean-up procedures or scrapped parts. Manufacturers can burn any application, fully unattended, worry-free. Even applications with unfavourable electrode/work piece geometry can be started with unusually high current density, and relied upon for flawless results.

Enhanced Software Configuration

Included in the EDAF series is Makino's new on-board programming system, Makino Program Generator (MPG), designed to make the Makino MGH control more user friendly, while generating more aggressive model plans to meet the demands of shortened lead times on today's shop floor. By providing answers to simple prompts, and inputting basic data, even novice operators will be able to generate efficient and safe burn routines. This new program generator also allows for programming of multiple electrodes and multiple burn locations.

Makino's High Quality Surface Finish (HQSF) technology provides the EDAF-series with improved electrical conductivity for more consistent discharging and spark diffusion. HQSF technology eliminates secondary discharges that waste energy while permitting increased efficiency of the sparks for a superior finish without a loss in metal removal rates. In addition, the HQSF technology allows for achievable surface finish capabilities that are 50 percent better than that of conventional achievable surface finishes, regardless of discharge surface area.
