EDAF2 and EDAF3 Designed for mold makers, these electrical-discharge machining (EDM) units from Makino are capable of accurate, high-speed machining and finishing. The smaller of the two, the EDAF2, has a rise-and-fall tank. The EDAF3 (shown at left) has a programmable drop tank that can be lowered to a level below the worktable. A dielectric reservoir is built into the EDAF3’s base. Both EDMs have a stationary worktable, built-in fire-extinguishing system and ultraviolet flame sensor that monitors the machining process.
What’s new? A variety of recent upgrades. They include the use of a liquid-cooled ball screw and the replacement of analog or semi-digital components with a fully digital generator, called the ES200A, and electrical components.
Benefits Faster, more efficient performance. With the upgrades, the EDMs now have about 25 percent more power — but use less energy; while as accurate and precise as before, they also are faster. These upgrades have reduced the cost of producing molds and mold components.
