Wire EDM Makino U86
Makino U86 – Wire EDM
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.
Machining Performance
Our 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 threaded 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 inches in 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.
Wire Electric Discharge Machine
Numbers matter. That’s why, with more than 140 patents, Makino is the world leader in EDM technology, providing faster processing times and superior surface finishes for even the most complex and involved part geometries.
By combining innovative Makino machine tools and software with game-changing support from Makino Engineering Services, shops of every size are competing and winning the kind of work that matters on the global EDM stage. The flexibility of Makino technology and proven turnkey engineering solutions allows for EDM solutions at all levels to help further reduce operational costs.
BellyWIZARD™ is an exclusive Makino wire EDM technology that automatically selects the optimum machining parameters for those applications that, top to bottom, require exceptionally straight parts. BellyWIZARD meets today’s manufacturing demands for lower costs, reduced lead-times and tighter tolerance by providing up to 40 percent improvement in part straightness with fewer passes than conventional wire EDM technology.
Additional Information:
Reduce Belly/Bow
One of the most difficult challenges faced by wire EDM operators is the machining of vertically straight workpieces to very close tolerances. Inaccuracies are usually at their worst in the center of the vertical span of a workpiece. These inaccuracies are typically defined as a “belly” or “bow” in the workpiece. Such an error occurs 90 percent of the time during the initial rough-cut operation.
The advantage of using BellyWIZARD wire EDM technology is that it reduces the belly or bow in workpieces during these roughing operations. By reducing the belly or bow in the rough cut, thus cutting closer to the final net shape, this technology reduces or eliminates the need for additional skim-pass machining.
When skim-pass machining is necessary to achieve finer surface finishes, BellyWIZARD helps to reduce the total cycle time and consumable costs by reducing the amount of error (belly/bow) and remaining material on the final part, thus leading to faster skimming times.
Improved Compensation
BellyWIZARD technology is built into the E-code, so that parameters change automatically with workpiece height. The technology compensates for changes in the wire caused by eroded wear and wire lag. This compensation is done by automatically machining on a slight taper in the rough cut and through adaptive servo movements. The result is that BellyWIZARD produces straighter and more accurate parts without increased wire consumption. The improvement in part straightness can be as much as 40 percent over conventional wire EDM technology. This reduction in both total cycle time and production costs makes your shop more profitable.
H.E.A.T. (High-Energy Applied Technology) is a Makino advancement in wire EDM technology that dramatically reduces cutting times while maintaining exceptional part straightness with one- or two-pass cutting accuracy.
• H.E.A.T. cuts parts 18 to 44 percent faster than conventional wire EDM approaches while holding tolerances of straightness to 0.0005″ (T.I.R.) with one pass and 0.0002″ (T.I.R.) with two passes.
• H.E.A.T. increases skim speeds by 50 to 100 percent in real-world applications and conditions including poor flushing situations, non-sealed nozzle applications, parts with uneven surface thickness and through holes as well as parts up to 6 inches tall.
• H.E.A.T. delivers high-speed performance in difficult, real-world EDM production environments, especially job shops specializing in medical, aerospace and similarly demanding parts.
New H.E.A.T. addresses all types of available wires for cutting tool steels:
• Brass and coated wires
• Paraffin and non-paraffin wires
• High zinc
H.E.A.T. generator enhancements:
• BellyWIZARD™ – Unmatched part straightness
• CornerWIZARD™ – Excellent geometry control
• PowerWIZARD™ – Superior wire-break prevention/optimized machining speed and flushing control
SurfaceWIZARD™ is an important innovation from Makino that improves performance in difficult, real-world production of EDM parts for medical, aerospace and other applications where precision and exceptional surface quality is required. SurfaceWIZARD is particularly useful in parts with variable shape, thickness or sudden changes in thickness, such as a stepped part. It also produces excellent results cutting through cross-drilled holes or other similar detail.
Before SurfaceWIZARD, burning parts of this kind would often leave “witness” lines, the telltale lines left at the transition from one-step thickness to the next. To remove witness lines, a part would require either bench work or secondary operations, each of which increases production costs and slows delivery. SurfaceWIZARD technology virtually eliminates witness lines and maintains part straightness.
Benefits of SurfaceWIZARD:
• Minimizes witness lines that occur due to material thickness and stepped changes
• Eliminates wire-break issues
• Improves part straightness
• Achieves more consistent, higher-quality surface finish
• Suppresses errors caused by changes in machining condition variables by employing new generator and adaptive control technologies
