Applications & Machining Capabilities

Used Nakamura-Tome Super NTJ CNC mill-turn center is designed for manufacturers that need to machine complex turned parts with additional milling, drilling, and angular machining operations.

Its twin-spindle and dual-turret design supports machining on both ends of a workpiece, while the upper turret's 182° B-axis swivel range makes angled drilling, inclined-surface milling, and multi-face machining possible without repeatedly repositioning the part.

Typical Applications

1. Aerospace Components

Suitable for machining precision shafts, fittings, mechanical connectors, and other complex aerospace-related metal parts where turning and milling operations are required.

2. Automotive & Transmission Parts

Applicable to drive shafts, transmission components, couplings, hydraulic connectors, and engine-related precision parts.

3. Medical Equipment Components

Can be used to machine suitable stainless-steel and other metal components for medical equipment, subject to required tolerances, process validation, and quality standards.

4. Hydraulic & Pneumatic Components

Suitable for valve components, hydraulic fittings, connectors, precision bushings, and other parts requiring multiple machining operations.

5. Industrial Machinery & Robotics

Applicable to precision mechanical parts, actuator components, shafts, couplings, and custom metal components used in automation equipment.

6. Precision Contract Manufacturing

A practical option for job shops handling complex parts, multiple machining operations, and production runs where reducing setup changes is important.

FAQ

Can the Super NTJ machine both sides of a part without manual repositioning?

Yes, the Super NTJ features opposed twin spindles that support workpiece transfer between the main and sub-spindle. This allows front- and back-side machining within an integrated process for suitable workpieces, helping reduce manual handling and additional setups.

What can I machine with the 182° B-axis turret?

The upper B-axis turret swivels from -91° to +91°, allowing angled drilling, inclined-surface milling, and multi-face machining. It is especially useful when a part requires machining at several different angles without repeated workpiece repositioning.

What is the maximum workpiece size for this used Super NTJ?

The Nakamura-Tome Super NTJ has a manufacturer-rated maximum turning diameter of 190 mm and maximum turning length of 620 mm. The actual machining envelope depends on the workpiece shape, chuck, tooling, and machining setup. Contact us to discuss your specific part requirements.
