Nakamura Tome JX-250

JX-250: Real Multi-Tasking Power with the World’s Shortest Tool Spindle “NT Smart Cube”

The Nakamura-Tome JX-250 is a high-end production center that delivers true multi-tasking machining capability with its ATC system, dual-spindle architecture, standard Y-axis on both turrets, and extended Z-axis cross-over movement.

Thanks to the “NT Smart Cube” tool spindle, the machine provides a more compact, precise, and rigid machining platform. With its wide spindle distance (up to 1,850 mm) and powerful milling performance, the JX-250 is designed to complete complex workpieces in a single setup.

Key Features

  • NT Smart Cube:
    Minimizes interference while delivering high rigidity and precision.
  • Y-Axis on Both Turrets:
    Enhances complex milling capability and machining flexibility.
  • Z-Axis Cross-Over Movement:
    Provides a large working area with R: 490 mm and L: 140 mm travel capacity.
  • Powerful Milling Performance:
    Equipped with a 5.5 / 3.7 kW milling motor operating up to 6,000 rpm.
  • ATC Capacity:
    Standard 40-tool capacity with optional 80 / 120-tool configurations.
  • Dual Spindle + Dual Turret Architecture:
    Enables parallel machining processes for shorter cycle times.
  • 1,850 mm Spindle Distance:
    Offers a spacious machining area for long and large workpieces.
