Nakamura-Tome NTRX 300

Montrasio GmbH offers you two excellent used NTRX 300 machines.

Machine Concept
- CNC turning/milling center (multitasking) with full 5-axis simultaneous machining
- 2 turning spindles (main spindle + counter spindle)
- B-axis milling head (swiveling milling head) + C-axes on the turning spindles
- Designed for complete machining (turning + milling + drilling + threading + contours)

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 passage / spindle bore: 71 mm
- Chuck diameter (typical for A2-8 version): 254 mm (10")

Main Spindle (Left)
- Spindle nose: A2-8
- Bar capacity: 71 mm
- Speed range: infinitely variable up to 4,500 rpm
- Spindle power (depending on spindle package): typically 22/18.5 kW (alternatively 15/11 kW possible depending on package)

Counter Spindle (Right)
- Design: full-featured counter spindle (part transfer/complete machining)
- C-axis available (for milling/indexing operations)
- Clamping device: hydraulic chuck (matching A2-8 configuration, typ. 10")

Milling Unit / 5-Axis Kinematics
Hnsdpfx Ajykvr Nebfjh
- 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 overhang under spindle center: 125 mm (for extended machining area)
- C-axis on main and counter spindle (C1/C2)

Tool / Milling Spindle (typical version)
- Milling spindle in B head, for drilling/milling/threading/simultaneous machining
- Speed (depending on package): typically 8,000 rpm (higher speeds optional)
- Power (depending on package): typically up to approx. 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 guidance
- 5-axis capable CNC platform (CAM-capable full machining, simultaneous operation)

Typical Application and Process Capability (for your listing)
- "Done-in-one" complete machining: turning + milling + drilling + threading + 5-axis contours
- Ideal for complex parts (e.g. aerospace, motorsport, demanding precision parts)
- Very well suited for automated production
