5-axis CNC machining center a900Z

horizontal60 toolsdirect-drive

Overview
The Makino a900Z is a horizontal 5-axis machining center with a factory-integrated Z-type fifth axis designed to machine complex geometries with fewer setups. It supports large workpieces up to Φ1250×1000 mm and a maximum pallet load of 1200 kg, providing high metal removal capability on a rigid three-point leveled bed.

Product details
The machine's kinematic layout minimizes force path lengths through the spindle and workpiece, efficiently transferring cutting loads into the three-point bed. This arrangement maximizes metal removal rates and extends tool life through superior system rigidity while leveraging the proven nx-series HMC platform.
