Nakamura-Tome vs Nakamura-Tome · CNC Lathes
Summary
The Nakamura-Tome SC-200 and the Nakamura-Tome SC-300II are two sizes of turning center from the same maker. The Nakamura-Tome SC-200 is the smaller machine, with an 8″ chuck, φ65mm bar capacity and a 317.8mm turning length. The Nakamura-Tome SC-300II takes a 10 in or 12 in chuck and turns parts up to 635 mm (25 in) long, twice the length.
The Nakamura-Tome SC-300II also passes larger bar: 71 mm (2.8 in) as standard, or 89 mm (3.5 in) with the extra-cost Ø89 mm option. The Nakamura-Tome SC-200 answers with a smaller footprint, 3,195mm wide by 1,967mm deep against 3,996 × 2,130 mm, and it stands 2,225mm high at the top of its moving parts against 2,300 mm.

Advantages
Nakamura-Tome SC-200
- Smaller footprint: 3,195mm wide by 1,967mm deep against 3,996 × 2,130 mm
- Lower machine, 2,225mm at the top of its moving parts against 2,300 mm
- 8″ chuck matched to smaller work that does not need a 10 in or 12 in chuck
Nakamura-Tome SC-300II
- 635 mm (25 in) turning length against 317.8mm, twice as long
- 71 mm (2.8 in) bar capacity against φ65mm, or 89 mm (3.5 in) with the Ø89 mm option
- 10 in or 12 in chuck against 8″
- Suited to heavy roughing of forgings and castings
Verdict
Pick by part size. The Nakamura-Tome SC-200 fits shops turning short parts in an 8″ chuck or from bar up to φ65mm, and it needs less floor: 3,195mm of width against 3,996 mm. The Nakamura-Tome SC-300II is the choice for longer parts up to 635 mm (25 in), for larger chucked work in a 10 in or 12 in chuck, for bar up to 89 mm (3.5 in) with the option, and for heavy roughing of forgings and castings.
