Twin ATC, B-Axis Multitasking System

Methods Machine Tools’ Nakamura-Tome Super NTMX multitasking turn-mill offers dual 24-tool ATC magazines. Full five-axis milling capability via a Fanuc 31iA5 control is said to provide high precision and accuracy for manufacturing complex contoured components in large or small volumes for the medical, aerospace and similar industries.

The dual ATC magazines enable tools to be separated from a central magazine and placed on the left or right spindle, depending on where they will be used. If 24 tools are insufficient for operations on one side, or if the operator wants to use the same tool for similar operations on both spindles, tools from the left magazine may be used on the right spindle or the right magazine on the left spindle. For simplified operations, the machine features easy access and fast setup via the front location of the ATC magazines and an easy-to-operate tool spindle, the company says. To increase tool changing speed, the inserts can be changed without stopping the machine.

The machine includes a lower turret with 12 stations and ½ index capabilities for a total of 24 available tools. The turret enables turning, drilling, boring, grooving and threading operations. The ATC magazines offer a maximum capacity of 48 tools. Spindle speeds range to 5,000 rpm at 15/10 hp. Other features include a 6" (150-mm) chuck and 2" (51-mm) bar capacity. A 10/5-hp tool spindle ranges in speed to 12,000 rpm. The distance between the spindles is 38.58" (980 mm) with a maximum turning diameter of 7.67" (195 mm) and a maximum turning length of 30.70" (780 mm). The system is offered in a 102 sq. ft. footprint with dimensions of 112.4" × 132" × 106.2" (2,855 × 3,353 × 2,697 mm).
