Advantages
DN Solutions DNX 2100
- 5,000 rpm main spindle against 2,500 (3,800) rpm (A8) and 1,800 rpm (A11)
- Suits small and medium diameters, where spindle speed keeps the cutting speed up
- Eccentric Turning cycle and DSSV spindle speed variation, which DN Solutions lists
Niles-Simmons N20 MC
- Six turning lengths, 1,000 | 1,500 | 2,000 | 2,500 | 3,000 | 3,500 mm, where the DN Solutions DNX 2100 has one at 1,100 mm (43 in)
- Spindle power of 34 | 30.4 kW (A8) or 40 | 31 kW (A11) against 18.5/15 kW (25/20 hp)
- Spindle torque of 655 | 580 Nm (A8) or 1,337 | 1,200 Nm (A11) against 326 N-m (240 ft-lb)
Verdict
Choose by part length and by how heavy the cut is. The DN Solutions DNX 2100 suits shafts and long parts up to 1,100 mm (43 in) in small and medium diameters, where 5,000 rpm keeps the cutting speed up. The Niles-Simmons N20 MC suits longer shafts, up to 3,500 mm on the longest version, and heavier turning, with 1,337 | 1,200 Nm on the A11 spindle against 326 N-m (240 ft-lb). For parts beyond 1,100 mm, only the Niles-Simmons N20 MC applies.
