Nakamura NTJ-100 Features Fast Cycle/Tool Change Time

Methods Machine Tools Inc.’s Nakamura-Tome NTJ-100 multitasking turn-mill center can handle low to high volume lots of medical, aerospace, general job shop components and more

The new Nakamura NTJ-100 multitasking center offers fast tool changes compared to a full tool spindle ATC machine. A large tool capacity, up to 54 tool stations for turning and 24 tool stations for milling tools, reduces setup time. For faster cycle times, the machine has two high rigidity turrets, each with a Y axis – 3.5” (80 mm) on the upper and 2.6” (65 mm) on the lower, facilitating pinch turn and pinch mill operations. An upper turret swiveling B axis with a range of 182 degrees, is ideal for easily producing angular features, eliminating the requirement for expensive angle milling heads.

Two milling tool motors can double the performance compared with traditional multitasking centers. Twin 6,000 min−¹ spindles offer faster motor acceleration and deceleration to improve machining efficiency. Synchronization of the left and right C axes is offered for parts simultaneously clamped by the left and right side chucks. The NTJ-100 has a maximum turning diameter of 6.9” (175 mm), a maximum turning length of 26.7” (678 mm) and a standard 1.6” (42 mm)/maximum 2.6” (65 mm) bar capacity.

The NTJ-100 provides X axis and Z axis speeds of 787 ipm and 1,574 ipm, respectively. Designed with a minimum 7.9” (200 mm) and maximum 35.8” (910 mm) distance between spindles to eliminate any interference of tooling during multitasking, the NTJ-100 allows for multiple tools in the cut simultaneously.
