Makino’s U86 Delivers Speed and Accuracy to Wire EDM Applications

Advanced Wire EDM Generator Improves Makino’s Award-Winning Design

MASON, OH—September 2008—The U86 relies on advanced generator technology, like H.E.A.T. and BellyWIZARD for significantly faster cycle times while achieving superior surface finishes and accuracies. With a rigid, compact design capable of handling large molds and dies within a small machine footprint, the U86 can slash cycle time by 50 percent while achieving high quality surface finishes of 35mRmax in just three machining passes.

Its sturdy, fixed-bed table brings maximum rigidity while its machining speeds reach up to 350mm2/min (32 inch2/hr). The end result is high-precision molds delivered more quickly than ever before. The U86 meets and exceeds the demanding tolerances of Wire EDM applications using the K-generator and its unique voltage waveform delivery and monitoring capabilities. High frequency electric pulses can be more efficiently delivered to the workpiece at nanosecond intervals, facilitating faster machining passes on the workpiece—even when removing larger amounts of material.

BellyWIZARD and H.E.A.T. technologies give this large Wire EDM the ability to cut at even higher speeds than standard technologies while producing parts up to 19 inches tall with straightness of 3 micron (0.00012 inch) T.I.R., top to bottom.

These enhancements are supported by the high-performance, advanced machining features of the U-Series Wire EDM machines. Makino’s award-winning drop tank design and fixed table eliminate dielectric weight shift during machining and improve servo reaction speed and precision. It The U86 design also improves operator efficiency and safety. The U86 has submersed machining capabilities of up to 19.7" and features a table capacity in excess of 6,600 lb., capable of handling workpieces up to 940 x 780 x 500 mm in size. Other features include the U86’s Dual Jet automatic wire threader and wire guiding system with built in "coreless" machining routines, and high precision positioning accuracy and repeatability of +/- .002mm.
