Original Press Release:



B-Axis Turning Center Provides Turning and Milling In A Single Setup



SUDBURY, MA - The multi-tasking Nakamura-Tome Super NTJ turning center completes multi-face angular machining and contour milling in a single setup, eliminating the need to refixture the part on another machine to perform secondary operations. This not only dramatically reduces overall production times and costs, it eliminates inaccuracies due to refixturing. With its advanced CNC software, this B-axis machine is capable of 9-axis machining with simultaneous 4+4 axis control.

The Super NTJ features a 5000 rpm 20 HP left-side spindle, a 5000 rpm 15 HP right-side spindle, and a dodecogonal 24-station lower turret (for both left and right spindles). The B-axis turret is capable of angular positioning to ±91° from horizontal, eliminating the need for angular work holders. The turret's direct drive provides high rigidity for milling, and the B-axis rotation is the world's fastest: 180°/second. Upper and lower turrets have maximum rotating tool speeds of 6000 rpm, and each has a capacity of 24 tools for turning or 12 tools for milling. Rapid traverses and chip-to-chip tool change times of 0.85 seconds minimize cycle times. Spindles offer increased efficiency through quick acceleration/deceleration.

Programming the Super NTJ is quick and easy with Luck-Bei II software. Tool offset values can be converted with a single G-code regardless of B-axis angle. Three-dimensional rectangular coordinate conversion can be carried out even on an inclined plane. CNC solid animation, M-code list display, and excess load detection software are also standard. Standard NT Work Navigator (torque type) software further reduces costs by eliminating the need for positioning jigs and fixtures.

Options include: the HAN-BEI-Mill in-process measuring system; PMS high-accuracy milling support software for programs with continuous minute blocks; and Net-Monitor software designed to integrate and manage multiple machine information from a personal computer and send alarms to a cell phone. Net-Monitor can also send advance notice of job completion in coordination with NT Nurse System 2, another software package that helps manage and monitor the Super NTJ.
