Nakamura Tome NTRX-300

High Rigidity & Maximum Flexibility

The NTRX-300 is a multi-axis turning center equipped with opposed twin spindles, a powerful B-axis tool spindle turret, extended X-Y stroke capacity, and a high-capacity ATC (Automatic Tool Changer) magazine. With a maximum turning diameter of 640 mm, machining length of 1,100 mm, and spindle distance of up to 1,350 mm, long, complex, and high-precision workpieces can be fully machined in a single setup.

This advanced configuration provides manufacturers with shorter cycle times, fewer setup requirements, lower production costs, and significantly higher productivity.

Key Features

  • Twin Spindle + B-Axis ATC Turret:
    Combines turning and 5-axis milling operations within a single machine, allowing complex parts to be completed in one setup.
  • Large Machining Capacity:
    Maximum turning diameter of 640 mm, machining length of 1,100 mm, and spindle distance up to 1,350 mm make it ideal for large and long workpieces.
  • 250 mm Square X-Y Stroke + 225° B-Axis Rotation:
    Enables machining of multi-surface geometries, angled surfaces, and complex milling/drilling operations.
  • ATC (Automatic Tool Changer) Magazine – Standard 40 Tools (Optional 60 / 80 / 120):
    Provides excellent flexibility for mass production and applications requiring multiple tools and complex machining operations.
  • High Rigidity & Low Center-of-Gravity Design:
    Vertical column and horizontal base structure ensure stability and precision even under high cutting forces.
  • User-Friendly Design:
    Large viewing window provides clear visibility of the machining area, while the spindle center location allows easy operator access from the front of the machine.
