DN Solutions SMX 2600 vs DN Solutions SMX 3100
DN Solutions vs DN Solutions · Mill-Turn Machines
Summary
The DN Solutions SMX 2600 and the DN Solutions SMX 3100 are mill-turn machines with the same working envelope. Both turn parts up to 660 mm (26 in) in diameter and 1,540 mm (61 in) long, both are rated 30 kW (40 hp), and both occupy 5,700 × 3,011 × 2,761 mm (224 × 119 × 109 in). The difference is the spindle: the SMX 2600 uses a 10 in chuck, the SMX 3100 a 12 in chuck.
The SMX 2600 spins faster, to 4,000 rpm against 3,000 rpm. The SMX 3100 delivers more torque, 1,203 N·m (887 ft-lb) against 724 N·m (534 ft-lb), and weighs 16,300 kg (35,935 lb) against 15,800 kg (34,833 lb).

Advantages
DN Solutions SMX 2600
- 4,000 rpm spindle against 3,000 rpm, for higher cutting speed on smaller diameters
- Lighter, at 15,800 kg (34,833 lb) against 16,300 kg (35,935 lb)
DN Solutions SMX 3100
- 1,203 N·m (887 ft-lb) of torque against 724 N·m (534 ft-lb)
- Takes a 12 in chuck against 10 in
Verdict
Pick by the cut, not the envelope, since both machines take the same 660 mm (26 in) by 1,540 mm (61 in) work at 30 kW (40 hp). The DN Solutions SMX 3100 suits large-diameter steel and chuck work where torque matters more than rpm, with 1,203 N·m (887 ft-lb) on a 12 in chuck. The DN Solutions SMX 2600 suits medium-diameter parts that benefit from its 4,000 rpm top speed on a 10 in chuck.
