Rotary table axes offer rotational motion of 240° (± 120°) on the A axis and a full 360° (continuous rotation) on the C axis.
The machine is equipped with a 15,000 rpm HSK-A63 spindle with 120Nm (42 Nm continuous) of torque.
A direct-drive motor technology in the D300’s C axis rotary table and A axis trunnion provides positioning accuracy and repeatability. The machine features roller linear guides across all linear axes for outstanding rigidity and stiffness while maintaining very productive rapid and feedrates.
3.5 sec tool change cycle
The new Matsuura LX-160 is a two-pallet, five axis vertical machining centre with X-Y-Z travels of 19.7 x 9.8 x 11.8 in. (500.38 x 248.92 x 299.72 mm) and a 46,000 rpm Fanuc control. The rotation centre of the tilting B axis is lowered to a position below the pallet surface to reduce each axis movement during simultaneous five axis machining, shortening cycle times. The tool change system shortens the change cycle to 3.5 seconds from chip-to-chip, a 65 per cent reduction compared to conventional Matsuura machines.
The machine features linear motor drives on all five axes, 3,600 ipm rapids on the X, Y and Z axes and 100 – 200 min-1 rapids on the B and C axes. The machine is designed with a large 6.3 x 7.9 in.

It incorporates Mazak’s MX Hybrid Roller Guide System, which increases vibration dampening, extends tool life, handles higher load capacities and eliminates tramp oil in the coolant by utilizing a greener grease-based lubrication system.
Cam-driven tool changing reduces non-cut times, offering 5-second chip-to-chip tool change cycles. The machine’s automatic tool changer stores up to 60 tools and accommodates maximum tool diameters of 10.24 in. (260 mm).
The machine is equipped with Mazak’s Windows 7-based Matrix Nexus 2 CNC control.
Workpieces up to Ø 6.5 ft/2 m
With a maximum workpiece size of 78.75 x 63 in. (2000 x 1600 mm) and a maximum loading capacity of 11,023 lb (5000 kg), the NHX10000 is an ideal solution for machining large workpieces up to Ø 6.5 ft (2 m) and difficult-to-cut materials, which are in great demand in the aircraft, construction machinery and energy industries.
Mori Seiki’s DCG (Driven at the Centre of Gravity) technology is used for the X and Z axis drive. DCG controls vibration and improves machining accuracy, reduces machining time and extends tool life.
For the B axis drive, a full indexing table equipped with DDM (Direct Drive Motor) is available as an option. By transmitting the drive power directly to the rotary axis, DDM eliminates backlash and provides outstanding transmission efficiency and high-speed feed.
