Two spindles, three turrets and three Y-axes

The Nakamura Tome Super NTY3 NTY3 twin-spindle machine has a Y-axis capability on each of its three turrets. Each turret has 24 tool positions, offering up to 7.5 kW of milling power on any station. With up to 72 driven tools available at any time, almost any component, however complicated, can be machined in one hit. By using all three turrets, operations can be balanced between the spindles to deliver the shortest possible cycle times. On complex medical or aerospace components, say, upper and lower turrets can use the same program to simultaneously machine opposite sides of any prismatic features, or perform simultaneous helical interpolation on the upper and lower faces. In fact, Nakamura says that the Super NTY3 can reduce cycle times by up to 60 per cent, compared to a twin-turret machine with just one Y axis. The Super NTY3 can swing parts up to 175 mm diameter and 588 mm, and has a chucking capacity of 165 mm diameter and a 42 mm bar capacity through either spindle – all within a footprint of just 2,780 x 1,970 mm. The Nakamura Tome Super NTY3 will be exhibited for the first time in the UK at the MACH 2008 exhibition as part of Turning Technology’s participation on the Engineering Technology Group stand.
