Makino is excited to announce the newest addition to our family of high capability horizontal machining centers, the five axis a500Z. 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” fourth / fifth axis combination 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 Ø24.8” (Ø630mm) x 19.9” (500mm) high, with payload weights up to 880 pounds (400kg). The X- and Y- strokes are 28.7” (730mm) and 29.5” (750mm) respectively, with the Z- stroke ranging from 19.7” - 27.6” (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.
