Doosan DNM 5700 vs Haas VF-3SS
Doosan Machine Tools vs Haas Automation · Vertical Machining Centers (VMC)
Summary
The Doosan DNM 5700 and the Haas VF-3SS are mid-size vertical machining centers with about the same X travel, 1,050 mm (41 in) against 40 in (1,016 mm), and the same rapids, 36 m/min (1,417 ipm) against 1,400 ipm (35.6 m/min). The Doosan is the wider, heavier-loading machine; the Haas is the faster, taller one.
The DNM 5700 has 570 mm (22 in) of Y travel against 20 in (508 mm), a 1,300 × 570 mm (51 × 22 in) table against 48 × 18 in (1,219 × 457 mm), and a 1,000 kg (2,205 lb) table load against 1,750 lb (794 kg). The VF-3SS spins to 12,000 rpm against 8,000 rpm, is rated 30 hp (22.4 kW) against 18.5 kW (25 hp), and has 25 in (635 mm) of Z travel against 510 mm (20 in).

Verdict
Choose the Doosan DNM 5700 for mold bases, plates and wide fixtures: it carries 1,000 kg (2,205 lb) and has 570 mm (22 in) of Y travel. Choose the Haas VF-3SS for aluminum parts and small tools at 12,000 rpm, for work that needs 30 hp (22.4 kW), and for tall parts or fixtures that use its 25 in (635 mm) of Z. X travel and rapids are the same, so the part's width, height and weight decide.
