CNC turning and milling center

Nakamura-Tome NTRX-300

The machine is currently operating in an Italian high-end facility specializing in individual components and custom manufacturing for Formula 1 as well as the aerospace sector. The machine is in exceptional condition. Photos are available upon individual request and under strict confidentiality.

CNC turning/milling center (multitasking) with full 5-axis simultaneous machining
- 2 turning spindles (main spindle + sub spindle)
- B-axis milling head (swivelling milling head) + C-axes on both turning spindles
- Designed for complete machining (turning + milling + drilling + threading + contouring)

Working area / capacities:
- Max. turning diameter: 640 mm
- Max. turning length: 1,100 mm
- Distance between spindle noses (min./max.): 250 / 1,350 mm
- Distance between centers (min./max.): 125 / 1,225 mm
- Bar capacity / spindle bore: 71 mm
- Chuck diameter (typical for A2-8 configuration): 254 mm (10")

Main spindle (left):
- Spindle nose: A2-8
- Bar capacity: 71 mm
- Speed range: stepless up to 4,500 rpm
- Spindle power (depending on spindle package): approx. 22/18.5 kW (alternatively 15/11 kW available depending on package)

Sub spindle (right):
- Design: fully-fledged sub spindle (workpiece transfer/complete machining)
- C-axis available (for milling/indexing operations)
- Clamping device: hydraulic chuck (compatible with A2-8 configuration, typically 10")

Milling unit / 5-axis kinematics:
- B-axis swivel range: 225° (−120° / +105°)

- Y-axis: ±125 mm (250 mm total)
- X/Y “square stroke” / machining window: 250 mm × 250 mm
- X-axis undercut below spindle center: 125 mm (for extended machining range)
- C-axis on main and sub spindle (C1/C2)

Tool / milling spindle (typical version):
- Milling spindle in B-head for drilling/milling/threading/simultaneous machining
- Speed (depending on package): approx. 8,000 rpm (higher speeds optionally available)
- Power (depending on package): typically up to 18.5 kW (package dependent)

Tool handling:
- Automatic tool magazine (ATC): 120 positions
- Automatic tool changer (magazine/ATC)

Control / software:
- Nakamura NT-Smart X user interface / process management
- 5-axis capable CNC platform (CAM-compatible complete machining, simultaneous machining)

Typical applications and process capability (for your listing):
- Complete “done-in-one” machining: turning + milling + drilling + threading + 5-axis contours
