DN Solutions DNX 2100 vs Nakamura-Tome NTJ-100
DN Solutions vs Nakamura-Tome · Mill-Turn Machines
Summary
The DN Solutions DNX 2100 and Nakamura-Tome NTJ-100 are both B-axis mill-turn machines, but they serve different jobs. The DNX 2100 turns up to 520 mm (21 in) in diameter on a 210 mm (8 in) chuck; the NTJ-100 turns up to 175 mm (6.9 in) and takes a 6 in chuck as standard, with 8 in available as an extra-cost option.
Both main spindles reach 5,000 rpm, and the NTJ-100's optional Ø65 mm spindle runs to 4,500 rpm. The DNX 2100 turns longer parts, 1,100 mm (43 in) against 678 mm (26.7 in), and has the stronger spindle at 18.5/15 kW (25/20 hp) against 11 / 7.5 kW. The NTJ-100 needs less floor: 3,799 × 2,110 mm against 4,615 × 2,285 mm.

Advantages
DN Solutions DNX 2100
- 520 mm (21 in) turning diameter against 175 mm (6.9 in)
- 1,100 mm (43 in) turning length against 678 mm (26.7 in)
- 18.5/15 kW (25/20 hp) spindle against 11 / 7.5 kW
Nakamura-Tome NTJ-100
- Smaller footprint: 3,799 × 2,110 × 2,565 mm against 4,615 × 2,285 × 2,630 mm
- Suited to small aerospace and medical parts with compound-angle holes and features
Verdict
Part diameter splits these two. The DN Solutions DNX 2100 is the machine for shafts and larger parts up to 520 mm in diameter and 1,100 mm long, with more spindle power behind them. The Nakamura-Tome NTJ-100 suits small, complex aerospace and medical parts within 175 mm in diameter, and fits shops moving up from Y-axis mill-turn work that have less floor space to give.
