DN Solutions DNX 2100 SB vs DN Solutions SMX 2100 STB
DN Solutions vs DN Solutions · Mill-Turn / Multi-Tasking Machines
Summary
The DN Solutions DNX 2100 SB and the DN Solutions SMX 2100 STB are two multitasking turn-mill machines from one maker, built around the same 10 in chuck, a 4,000 rpm main spindle rated at 22 kW and a 5,000 rpm sub-spindle. The step up to the SMX 2100 STB buys swing and torque, at the cost of a much heavier machine.
The SMX 2100 STB turns 600 mm (24 in) in diameter against 520 mm (21 in) and delivers 512 N·m (378 ft-lb) against 456 N-m (336 ft-lb). The DNX 2100 SB takes slightly longer work, 1,100 mm (43 in) against 1,040 mm (41 in), and weighs 11,000 kg (24,251 lb) against 15,900 kg (35,054 lb), on a footprint of 4,615 × 2,285 mm against 4,845 × 2,770 mm.

Advantages
DN Solutions DNX 2100 SB
- 1,100 mm (43 in) turning length against 1,040 mm (41 in)
- Lighter machine: 11,000 kg (24,251 lb) against 15,900 kg (35,054 lb)
- Smaller footprint: 4,615 × 2,285 × 2,630 mm against 4,845 × 2,770 × 2,777 mm
DN Solutions SMX 2100 STB
- 600 mm (24 in) turning diameter against 520 mm (21 in)
- 512 N·m (378 ft-lb) of main spindle torque against 456 N-m (336 ft-lb)
Verdict
Choose the DN Solutions SMX 2100 STB when parts exceed 520 mm (21 in) in diameter or when roughing needs its 512 N·m (378 ft-lb), and the floor can take a 15,900 kg (35,054 lb) machine. Choose the DN Solutions DNX 2100 SB for shaft-type parts up to 1,100 mm (43 in) and for two-sided work inside its smaller swing: it has the same chuck size, spindle speeds and rated power in a lighter, smaller machine.
