NTY3-250
Nakamura-Tome’s latest multitasking platform, the NTY³-250 is the most productive 3-turret machine available for today’s high-precision manufacturers.
The NTY3-250’s large distance between spindle faces at 47.2″ allows for no interference issue to have multiple tools in the cut simultaneously, helping you optimize cycle time reduction with ease.
The new 19″ LCD SmartX control makes the operator interface more user-friendly, with 30% fewer buttons and switches.
