DN Solutions MYNX 5400 II vs Doosan DNM 5700
DN Solutions vs Doosan Machine Tools · Vertical Machining Centers (VMC)
Summary
The DN Solutions MYNX 5400 II and the Doosan DNM 5700 are vertical machining centers of the same size, with about 1,020 mm (40 in) and 1,050 mm (41 in) of X travel, a 1,000 kg (2,205 lb) table load and an 8,000 rpm spindle each. What separates them is spindle torque.
The MYNX 5400 II delivers 286.5 N·m (211 ft-lb) against 117.8 N·m (87 ft-lb), more than twice the torque, from a 15 kW (20 hp) spindle. The DNM 5700 has the higher power rating at 18.5 kW (25 hp), faster rapids at 36 m/min (1,417 ipm) against 30 m/min (1,181 ipm), and a larger table, 1,300 × 570 mm (51 × 22 in) against 1,200 × 540 mm (47 × 21 in). It is also slightly lighter, 6,500 kg (14,330 lb) against 7,000 kg (15,432 lb).

Advantages
DN Solutions MYNX 5400 II
- 286.5 N·m (211 ft-lb) of spindle torque against 117.8 N·m (87 ft-lb)
- 530 mm (21 in) of Z travel against 510 mm (20 in)
Doosan DNM 5700
- 18.5 kW (25 hp) spindle power against 15 kW (20 hp)
- 36 m/min (1,417 ipm) rapid traverse against 30 m/min (1,181 ipm)
- 1,300 × 570 mm (51 × 22 in) table against 1,200 × 540 mm (47 × 21 in)
- Slightly more X and Y travel: 1,050 mm (41 in) and 570 mm (22 in)
Verdict
Choose the DN Solutions MYNX 5400 II for steel and cast-iron work with large face mills and drills at low speed, where 286.5 N·m (211 ft-lb) of torque decides the cut. Choose the Doosan DNM 5700 for general machining and multi-vise setups, where its 1,300 × 570 mm (51 × 22 in) table, 18.5 kW (25 hp) spindle and 36 m/min (1,417 ipm) rapids are worth more than low-end torque. Load limit and top speed are the same.
