FAQ
What is the Nakamura-Tome NTRX-300L lathe-mill?
An extended version of the NTRX-300 for machining very long workpieces – it combines turn-mill versatility with a 1850 mm spindle distance for demanding industrial applications.
What are the main differences between the NTRX-300L and the standard NTRX-300?
The increased distance between spindles to 1850 mm and the optional steady rest enable working with much longer workpieces while maintaining all the advantages of the basic model.
What part sizes does the NTRX-300L support?
1850 mm distance between spindles adapted to very long workpieces – ideal for complex, large-sized components in industrial production.
How does the optional steady rest increase stability?
The steady rest eliminates vibrations and deformation – providing exceptional stability when machining long workpieces during intensive cutting operations.
What tooling options does the machine offer?
Additional magazine for up to 123 tool holders, including extra-long tools – exceptional flexibility, shorter changeovers and support for production automation.
What operations does a B-axis milling spindle enable?
The B-axis milling spindle performs five-axis operations – turning, milling and drilling at a variable angle in one setting without additional operations.
How does the dual-spindle design improve performance?
Two turning spindles enable simultaneous machining of two workpieces or comprehensive machining of one – reducing cycle times in serial and piece production.
Why choose the Nakamura-Tome NTRX-300L lathe-mill?
1850 mm between spindles, steady rest, 123 tools, B-axis and dual-spindle design – maximum versatility and precision for very long workpieces.
