Multitasking Turning Centers Enable Heavy-Duty Machining

Methods Machine Tool introduces the Nakamura-Tome NTRX-300 and the NTRX-300L multitasking turning centers.

Methods Machine Tool introduces the Nakamura-Tome NTRX-300 and the NTRX-300L multitasking turning centers. The NTRX-300L is 20" (1,850 mm) longer in the Z axis than the NTRX-300, offering a larger work envelope for larger part applications plus three additional tools with a maximum length of 15.75" (400 mm) in a separate storage area.

The NTRX-300 offers true opposing twin spindles and can be equipped with 8" A2-6 25-hp or 10" A2-8 30-hp spindles. The machine also features a 25-hp tool spindle with 12,000 rpm and full five-axis capabilities with FANUC 31I A5 control. The Y-axis travel measures 10" (250 mm) while the below-center X-axis travel measures 5" (125 mm). The NTRX-300 is available in two models, with 8" (203-mm) chucks and 2.5" (63.5-mm) bar capacity or with 10" (250-mm) chucks with 3.15" (80-mm) bar capacity.

The larger NTRX-300L features a 72.83" (1,850 mm) distance between spindles and is designed to eliminate tooling interference during multitasking. The machine features standard 40-station automatic toolchanger (ATC) and can be equipped with a 80- or 120-tool ATC as an option.

Both the NTRX-300 and NTRX-300L feature a bed design with a vertical column structure mounted on a horizontal machine bed for rigidity and thermal stability. They are equipped with CAMplete TruePath Turn/Mill software as well as Nakamura-Tome (NT) Smart X Operation Software, which offers an operation-level management function to view operator clearance level; a productivity monitor function showing the status, productivity graph and capacity utilization of the machine; and a loading monitor function that provides detailed load information. An NT Collision Guard feature protects against machine collision and includes an air bag function to minimize damage in the event of a collision. Voice guidance, production management and 3D collision check are also included.
