Reliable and efficient production with 5-axis flexibility
This versatile machine builds upon the industry leading performance and reliability of our nx-series four axis HMC’s, adding a factory built and fully integrated “Z-type” fifth axis to accommodate today’s more complex part geometry challenges in a minimum number of workholding setups and machining operations.
The unique kinematic arrangement of the a500Z minimizes the force path lengths both through the spindle as well as through the workpiece, efficiently transferring both cutting loads and reactive forces into the machine’s three point leveled bed, maximizing both metal removal rates and perishable tool life due to unparalleled system rigidity.
The a500Z accommodates workpieces of up to Ø630mm x 500mm high, with payload weights up to 400kg. The X- and Y- strokes are 730mm and 750mm respectively, with the Z- stroke ranging from 500mm – 700mm, depending on the rotary axes positioning. Both rotary tables are of the direct drive type, with unlimited 360° movement on the B-, and 180° on the innovative ‘slant style’ C-axis unit. This allows a full range of workpiece positioning ranging from the pallet top sitting horizontal to the spindle centerline to parallel to the spindle centerline, or anywhere in between these two extremes. As has long been Makino’s hallmark, all axes on the a500Z have closed loop active temperature control standard, providing not only the superior dimensional control that is inherent to this design, but also extended component life even in the most demanding production environments.
