U3 H.E.A.T

Builds on the diverse capabilities of the U3 by adding enhanced technologies that boost productivity

The Makino U3 H.E.A.T. (High Energy Applied Technology) configuration contains enhancements to the flushing and filtration system that dramatically increase cutting speed, especially in poor flush applications, while maintaining part straightness and accuracy. The U3 H.E.A.T. harnesses the raw horse power from its larger capacity independent dual flushing pumps to deliver higher pressure and volume of flushing to machining to reduce Rough Cut cycle time. The machine is also standard with a larger capacity (4) filter filtration system to accommodate the higher capacity flushing capability.

The U3 H.E.A.T. utilizes a Split-V Wire Guide system that requires less maintenance and last 34 times longer than traditional Round Wire Guides. Machine maintenance and consumable wear items are also reduced when compared to traditional designs, which provides greater productivity while reducing operational costs. The (4) di-electric filters are housed in a non-submerged cabinet with an integrated Filter Air-Purge function that evacuates the water from the filters before exchanging, reducing weight of the spent filter and preventing the traditional dirty, wet slip hazards that are normally encountered with filter replacement.

The U3 H.E.A.T. features Makino’s Hyper i control that provides intuitive and familiar touch Pinch/Swipe/Drag operations similar to smartphones and tablets.  This efficient and user-friendly interface is used for all Makino Wire and RAM EDM machines, and utilizes a straightforward 3-Step operation process of Program/Setup/Run.  The operator is provided with an effective and commanding view of the control with the large 24” class HD touch-screen display that is further enhanced with a standard mouse and keyboard.  The Hyper i control is also standard with a full-function advanced Handbox that provides greater convenience and flexibility, and contains digital onboard electronic manuals, instructional training videos, and advanced E-Tech Doctor help functions that empower and support the operator with integrated resources right at their fingertips.

Like the U3, the U3 H.E.A.T. utilizes a space-savings design that integrates the di-electrode reservoir into the base machine casting, reducing the footprint while improving thermal stability.  The stationary work table design delivers repeatable accuracy regardless of work piece size or weight, and excellent access to the work tank is provided by the pneumatic raise and fall front door that allows access to the underside of the work piece or lower machine head even with a large work piece on the table.  The U3 H.E.A.T. contains a robust machining conditions library that has been developed to provide an optimal mix of Speed, Accuracy, Surface Finish, and Low Wire Consumption for both sealed and poor flush applications.  As the industry leader in low wire consumption technologies, Makino has worked to reduce the single largest expenses in operating a wire EDM machine, providing efficient and user-friendly operation that achieves new levels in productivity for the most demanding applications.

U3 H.E.A.T. enhancements from U3:

  • Standard 4-Sided hardened work table
  • Split-V Wire Guide System
  • Higher capacity flush pumps (2 pumps)
