FAQ

Can the used Nakamura-Tome WT-300 perform turning and milling in the same machine?

Yes. The WT-300 is designed as a multitasking CNC turning center with live-tooling capabilities. It can combine turning with operations such as milling and drilling, subject to the installed tooling and control options. This helps reduce the need to move parts between different machines.

Can the two spindles and turrets work simultaneously?

Yes. The opposed-spindle and dual-turret design supports simultaneous machining operations where the workpiece, tooling, and CNC program allow. Nakamura-Tome also specifies up to 30 kW of cutting power for suitable shaft work supported by synchronized spindles.

Does this Nakamura-Tome WT-300 have 48 tool stations?

The manufacturer specifies a maximum capacity of up to 48 tools using suitable holders and turret indexing positions. The machine has two 12-sided turrets, each supporting up to 24 indexing positions. The actual number of installed or included tools should be confirmed before purchasing.
