Reliable and efficient production with 5-axis flexibility
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.
