Machine Comparison
DN Solutions DNX 2100 vs Index G220
DN Solutions vs Index-Traub · Mill-Turn Machines
Summary
The DN Solutions DNX 2100 and Index G220 are both 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, while the Index G220 is a smaller-diameter machine, turning up to 220 mm (8.66 in) with a 165 mm (6.5 in) chuck.
The DNX 2100 also turns longer parts, 1,100 mm (43 in) against 660 mm (26 in), and has more spindle torque, 326 N-m (240 ft-lb) against 125 / 170 Nm. The Index G220 spins faster, 6,000 rpm against 5,000 rpm, and its spindle is rated 20 / 24 kW against 18.5/15 kW (25/20 hp).

Advantages
DN Solutions DNX 2100
- 520 mm (21 in) turning diameter against 220 mm (8.66 in)
- 1,100 mm (43 in) turning length against 660 mm (26 in)
- 326 N-m (240 ft-lb) of spindle torque against 125 / 170 Nm
Index G220
- 6,000 rpm spindle against 5,000 rpm
- Spindle rated 20 / 24 kW against 18.5/15 kW (25/20 hp)
- Suited to complex aerospace and medical parts in titanium, Inconel and hardened steel
Verdict
These machines fit different part sizes. The DN Solutions DNX 2100 is the one for shafts and larger parts, up to 520 mm in diameter and 1,100 mm long, where its 326 N-m of torque counts. The Index G220 suits smaller, complex aerospace and medical components within 220 mm in diameter, where the 6,000 rpm spindle and its 20 / 24 kW rating are the better match.
