A part of Makino’s award-winning U-Series of wire EDM machines, the U86 relies on advanced generator technology for significantly faster cycle times while achieving superior surface finishes and workpiece accuracy. 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. The end result is high-precision molds delivered quickly. 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—even when removing larger amounts of material. The U86’s servo optimizes speeds and feeds in reaction to the voltage waveforms. This translates into aggressive metal removal rates, which are achieved without any workpiece distortion.

Additional Information

Machining Performance
WIRE EDM Our New WireWIZARD operating system improves operating ease. The unique drop tank design allows setup work to be done easily from three sides. WireWIZARD technologies deliver high speed machining capability and superior accuracy. These unique features select the optimum machining conditions even for shapes where water pressure changes can occur, such as when starting to machine from the edge of a workpiece.

10-Year "Ballscrew" Warranty
We are so confident in our design and construction that we warrant our ballscrews for 10 years.

Machining Accuracy
Because superb roundness equal to that of jig grinders is obtained, the part shape and guide pin holes can be machined simultaneously. This makes it possible to improve overall product accuracy as well as to shorten lead times.

Patented, Low Maintenance Automatic Wire Threading
The wire is treaded in 15 seconds from the time a break occurs. With the standard specification, automatic threading is possible for start holes as small as 0.19" diameter.

Powerful Programmable AWT Functions
Optimize unattended machining by integrating a variety of Autothreading methods including High Speed, Small Hole and Normal, randomly within the same program based on the application.

Long Life Wire Guides
Get at least 12,000 machining hours out of single set of Wire guides. Virtually eliminate vertical alignment of the Wire since the guides do not require removal for cleaning.
