DN Solutions vs DN Solutions · Mill-Turn Machines
Summary
The DN Solutions DNX 2100 and DN Solutions SMX 3100 are both B-axis mill-turn machines, but the SMX 3100 is the bigger of the two. It takes a 12 in chuck against the DNX 2100's 210 mm (8 in), turns up to 660 mm (26 in) in diameter against 520 mm (21 in), and up to 1,540 mm (61 in) long against 1,100 mm (43 in).
The SMX 3100's spindle is built for torque: 30 kW (40 hp) and 1,203 N·m (887 ft-lb) against 18.5/15 kW (25/20 hp) and 326 N-m (240 ft-lb). The DNX 2100 spins faster, 5,000 rpm against 3,000 rpm, which keeps cutting speed up on smaller diameters, and it occupies 4,615 × 2,285 mm of floor against 5,700 × 3,011 mm.

Advantages
DN Solutions DNX 2100
- 5,000 rpm spindle against 3,000 rpm for small and medium diameters
- Smaller footprint: 4,615 × 2,285 × 2,630 mm against 5,700 × 3,011 × 2,761 mm
DN Solutions SMX 3100
- 1,203 N·m (887 ft-lb) of spindle torque against 326 N-m (240 ft-lb)
- 30 kW (40 hp) spindle against 18.5/15 kW (25/20 hp)
- 660 mm (26 in) turning diameter and 1,540 mm (61 in) turning length against 520 mm (21 in) and 1,100 mm (43 in)
Verdict
The DN Solutions SMX 3100 is the choice for large chuck work, shafts and housings up to 1,540 mm long, where torque matters more than rpm. The DN Solutions DNX 2100 fits shops whose parts stay within 520 mm in diameter and 1,100 mm long, where its 5,000 rpm spindle keeps surface speed up on smaller work and the machine takes less floor space.
