NAKAMURA-TOME NTJ-100 HORIZONTAL MACHINING CENTER

The Nakamura-Tome NTJ-100 is a sophisticated 10-axis multitasking turning center engineered for complex precision machining operations. This machine features dual opposed spindles, each rated at 6,000 RPM with 15 HP motors, enabling simultaneous cutting on both sides for balanced processes and reduced cycle times. The primary upper turret accommodates 30 turning tools and 12 rotary tools, while the secondary lower turret holds 24 turning tools and 12 rotary tools, providing exceptional tool capacity for intricate workpieces. The NTJ-100 handles workpieces up to 6.89 inches in maximum turning diameter with 26.69 inches of turning length using a 6-inch chuck and accepts bar stock up to 1.65 inches diameter. The upper and lower turrets feature integrated B-axis swivel capability with a 182-degree range and Y-axis positioning (80mm upper, 65mm lower), enabling profile milling, angular drilling, and contour operations with both turning and milling functionality performed simultaneously. The machine delivers impressive feed rates of 787 ipm across X, Y, and Z axes with maximum Z-axis traverse of 1,574 ipm. Its 10-axis configuration includes C-axis indexing at 1E-3 degree increments with stepless rotation tool stations, ensuring exceptional flexibility for off-center milling operations with C-axis synchronization. Rotary driven-tool stations operate at 6,000 RPM with 7.5 HP motors on each turret. This configuration makes the NTJ-100 ideal for manufacturing automotive components, aerospace parts, and complex medical devices requiring integrated turning and milling in single setups.
