The a900Z accommodates workpieces of up to Ø49.2” (Ø1250mm) x 39.4” (1000mm) high, with payload weights up to 2,750 pounds (1250kg).  The X- and Y- strokes are 55.1” (1,400mm) and 47.2” (1,200mm) respectively, with the Z- stroke ranging from 46.7” - 49.8” (1,185mm – 1,265mm), 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 a900Z 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.  With rapid rates for all linear axes of 2,362 inches per minute (60 meters per minute), and a B-axis rotation rapid rate of 18,000 degrees per minute, this agile platform allows for highly efficient machine movements.
 
The a900Z’s standard 10,000 RPM high power spindle offers output capabilities of 73.8 HP (55 kW) peak power, and 532 ft-lbs (721 N-m) peak torque, making is ideal for wide ranging material applications.  The optional 8,000 RPM high torque spindle is offered for customers machining tool materials and hard metals.  Tool changer magazine sizes range from the standard 60 tool capacity ring type unit, and the optional 185 tool capacity matrix type.

The standard automatic pallet changer on the a900Z greatly increases machine utilization, allowing workholding fixture tending on one pallet while the other pallet’s workpiece is being machined.  Since the APC is fully integrated into the core of the a900Z, it offers both unparalleled operation ease and system reliability.

The a900Z comes standard with our Fanuc based Pro-6 CNC control, featuring standard features such as a user-friendly touch screen interface, advanced tool data management, and our patented Makino Super Geometric Intelligence (SGI.5) high speed machining control system.  The Makino a900Z - the industry’s newest heavyweight in the complex production parts machining arena!
