Nakamura-Tome SC-300II vs Nakamura-Tome WT-150II
Nakamura-Tome vs Nakamura-Tome · CNC Lathes
Summary
The Nakamura-Tome SC-300II and the Nakamura-Tome WT-150II sit in different size classes and serve different jobs. The Nakamura-Tome SC-300II is a 10 in or 12 in chuck lathe for large chucked parts and heavy roughing. The Nakamura-Tome WT-150II is a 6 in chuck machine, with an 8 in chuck as an extra-cost option, for small parts machined on both sides.
The Nakamura-Tome SC-300II turns 360 mm (14.2 in) in diameter against 190 mm (7.5 in) and 635 mm (25 in) in length against 515 mm (20.3 in), with a 22 / 18.5 kW spindle against 15 / 11 kW. It takes 71 mm (2.8 in) bar against 51 mm (2 in); each machine has an extra-cost larger-bar option, 89 mm (3.5 in) and 65 mm (2.6 in). The Nakamura-Tome WT-150II is faster at 5,000 rpm against 3,500 rpm, or 4,500 rpm with the Ø65 mm option.

Advantages
Nakamura-Tome SC-300II
- 360 mm (14.2 in) turning diameter against 190 mm (7.5 in)
- 635 mm (25 in) turning length against 515 mm (20.3 in)
- 22 / 18.5 kW spindle against 15 / 11 kW
- 71 mm (2.8 in) bar capacity against 51 mm (2 in), with 89 mm (3.5 in) as an extra-cost option
Nakamura-Tome WT-150II
- 5,000 rpm spindle against 3,500 rpm
- Suited to small parts machined on both sides in one machine
Verdict
Choose by part size. The Nakamura-Tome SC-300II is for flanges, hubs, forgings and castings up to 360 mm (14.2 in) in diameter that need 22 / 18.5 kW, and for bar up to 89 mm (3.5 in) with the extra-cost option. The Nakamura-Tome WT-150II is for small two-sided parts and shafts within 190 mm (7.5 in) and 515 mm (20.3 in), where 5,000 rpm suits small diameters. The two rarely compete for the same part.
