EDAF2 RAM EDM

SPEED, REPEATABILITY AND EASY OPERATION
TO MAKE THE PRECISION PARTS THAT MATTER
 
The EDAF2 sinker EDM machine offers an ideal mix of high-speed machining, high accuracy and surface finish capability to efficiently tackle any job. At the heart of the machine is a robust and rigid structure that provides sustained long-term precision. The EDAF2 has a space-saving design that integrates the dielectric reservoir into the base casting of the machine, which reduces floor space requirements while improving thermal stability. The machine’s thermal stability is further enhanced with active liquid cooling of the Y-axis and Z-axis structures that keeps the entire machine at a stable temperature.
 
The EDAF2 offers a flexible machine design that utilizes a stationary worktable with a programmable rise-and-fall work tank. Operators will find that the machine provides excellent operator ergonomics with superb access to the work tank, and the design simplifies the integration of ATC (automatic tool changer) and automation systems to extend unmanned operation. The EDAF2 is available with an optional 50mm (2.0”) and 100mm (4.0”) table-down configuration that provides additional depth to the work tank. Operational safety is also a vital requirement, and the EDAF2 features a standard built-in fire extinguishing system and U/V flame sensor that monitors the machining process.  
          
The EDAF2 is loaded with machining technologies that deliver optimum productivity for every application.  Makino’s proprietary generator and adaptive power control technologies ensure efficient machining while achieving the highest level of accuracy and surface integrity. Dedicated settings such as HyperCut, SuperSpark™ IV and ArcFree empower the operator with practical tools to accomplish a wide variety of work. The powerful yet user-friendly Hyper-i control system complements and elevates the capability of the EDAF2 into a streamlined package that delivers a paradigm shift in efficiency and productivity to all operations.

A new on-board programming system, Makino Program Generator (MPG), was designed to make the powerful 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.

ArcFree technology is standard on these new machines. In the past, if a CNC sinker happened to develop a destructive DC arc during machining, the job would have to be stopped, and both the workpiece and the electrode would require cleanup of the area that was arced. Sometimes the electrode or the workpiece, or both, would be scrapped due to this DC arc activity. All modern sinker EDM machines have anti-arc, or arc prevention, circuits. The EDAF-Series machines have the most highly sophisticated spark gap monitoring and arc prevention circuits available today. This new technology will provide peace of mind, as the machines can be relied upon to burn any application, unattended, with virtually no possibility of developing a destructive DC arc during the course of the burn. Even jobs that offer less-than-optimal surface areas of burn due to electrode/workpiece geometry can easily be started with unusually high current density, and can be relied upon to perform flawlessly throughout the burn.

Both EDAF models will be available with a fine-hole option and HQSF™ (High-Quality Surface Finish) capability. Other standard and/or optional performance enhancing features include Makino’s Z-axis stabilizer, dielectric fluid cooling unit, ram temperature controller, and high-precision Mi C-axis head. A new power-saving mode automatically activates at the end of machining, reducing the machine’s power consumption while idle by 70 percent.

Relying on Makino’s proven rise-and-fall drop-tank design, the EDAF-Series is user-friendly and favorable for automation. The EDAF2 and EDAF3 can be factory ordered for left-hand- or right-hand-mounted controls, facilitating easy integration of one or more machines with a variety of commercially available electrode and work-pallet handling robots.
