Doosan DNM 6700 vs DN Solutions MYNX 6500/II
Doosan Machine Tools vs DN Solutions · Vertical Machining Centers
Summary
The Doosan DNM 6700 and DN Solutions MYNX 6500/II are vertical machining centers of the same size class: both have 670 mm (26 in) of Y, 625 mm (25 in) of Z, a 1,300 kg (2,866 lb) table load and an 8,000 rpm spindle. X travel is 1,300 mm (51 in) against 1,270 mm (50 in). The real difference is in the spindle.
The DNM 6700 has the more powerful motor, 18.5 kW (25 hp) against 15 kW (20 hp), faster rapids at 36 m/min (1,417 ipm) against 30 m/min (1,181 ipm), and a longer 1,500 × 670 mm table against 1,400 × 670 mm. The MYNX 6500/II has far more torque, 286.5 N·m (211 ft-lb) against 117.8 N·m (87 ft-lb), and is the heavier machine at 9,000 kg (19,842 lb) against 8,500 kg (18,739 lb).

Advantages
Doosan DNM 6700
- 18.5 kW (25 hp) spindle against 15 kW (20 hp)
- 36 m/min (1,417 ipm) rapids against 30 m/min (1,181 ipm)
- 1,500 × 670 mm table and 1,300 mm (51 in) of X against 1,400 × 670 mm and 1,270 mm (50 in)
DN Solutions MYNX 6500/II
- 286.5 N·m (211 ft-lb) of spindle torque against 117.8 N·m (87 ft-lb)
- Better suited to roughing steel and mold bases with large cutters, where torque counts more than rapid speed
Verdict
For roughing steel and mold bases with large-diameter cutters, the DN Solutions MYNX 6500/II is the better fit: it delivers 286.5 N·m at the spindle against 117.8 N·m. For finishing, moderate roughing and work where non-cutting time counts, the Doosan DNM 6700 is ahead with 18.5 kW, 36 m/min rapids and the longer 1,500 × 670 mm table. Both carry the same 1,300 kg.
