Three-Turret Multitasking Center

The Nakamura-Tome multitasking turning center is said to offer 100-percent stock-on turning and machining that virtually eliminates lost productivity from tool changes. The Super NTY3 has three turrets, each with a Y axis—all in a relatively small footprint (109.45" × 77.6"). It features one-pass complete turning, machining and finishing as well as reducing part cycle times.

The turning center offers multi-point machining with process integration, combining turning and milling capabilities in one machine. Its three, 6,000-rpm milling motors can simultaneously machine two flat surfaces (top and bottom) on one spindle and one surface on the other. Each rigid turret holds 12 driven or 24 stationary tools for a maximum of 72 tool stations. Accelerating Y axes have travels of 2.44" (62 mm). Up to 29/20-hp is available for shaft/work turning with synchronized spindles (14.5/10-hp per spindle). The center has a maximum turning diameter of 6.89" (175 mm), a maximum turning length of 23.5" (588 mm) and bar capacity of 1.65" (42 mm).

The turning center features the Fanuc 31iA CNC with nanometer resolution designed for smooth movement and improved accuracy. Overload detection and NT Nurse programming/monitoring software are also standard, as is NT Work Navigator (torque-type) software, which is said to reduce costs by eliminating the need for positioning jigs and fixtures.
