Wire EDMs offer affordability, reduced cycle times

A new, affordable sinker EDM is designed to facilitate unattended operation for entry-level applications. The Edge2 Series 2000 sinker EDM (pictured) is capable of correcting variables including on/off time, jump parameters, and current. According to the manufacturer, the systems can machine small, intricate jobs and deep ribs accurately and reliably without trial runs and regardless of operator skill; novice users can write complete programs with a few inputs from the Single Page Program macro.

Standard features promoting unattended operation include an eight- or 16-station automatic electrode changer and an MR rotating head capable of standard z-axis high-speed pulse machining at 10 m/min. The fixed table reportedly eliminates dielectric weight shift during machining and improves servo reaction speed and precision.

A servo design provides cycle time jump rates of 393 in/min and surface finishes within 2 mm. It features 12-by-10-by-10-inch travels and weighs 6000 lb.

Also from Makino is a wire EDM machine that?s reportedly capable of delivering cycle times up to 50 percent faster. The newest in the U Series wire EDM machines, the U86 is capable of handling large molds within a small machine footprint.

Submersed machining capabilities of up to 19.7 inches and a table capacity in excess of 6600 lb make the U86 capable of handling workpieces up to 940 by 780 by 500 mm. A Dual Jet automatic wire threader and wire guiding system reportedly allow accuracy to within 1 mm for positioning with ±2-mm repeatability.
