Doosan DNM 4500 vs Haas VF-2SS Super Speed VMC
Doosan Machine Tools vs Haas Automation · Vertical Machining Centers (VMC)
Summary
The Doosan DNM 4500 and the Haas VF-2SS Super Speed VMC are small vertical machining centers with nearly the same envelope: 800 mm (31 in) against 30 in (762 mm) of X, 510 mm (20 in) against 20 in (508 mm) of Z, and rapids of 36 m/min (1,417 ipm) against 1,400 ipm (35.6 m/min). The spindle is where they part.
The Haas runs to 12,000 rpm against 8,000 rpm and is rated 30 hp (22.4 kW) against 18.5 kW (25 hp). Its table also carries a little more, 1,500 lb (680 kg) against 600 kg (1,323 lb). The Doosan gives more room across the table: 450 mm (18 in) of Y against 16 in (406 mm), and a 1,000 × 450 mm (39 × 18 in) table against 36 × 14 in (914 × 356 mm).

Advantages
Doosan DNM 4500
- 450 mm (18 in) of Y travel against 16 in (406 mm)
- 1,000 × 450 mm (39 × 18 in) table against 36 × 14 in (914 × 356 mm)
- 800 mm (31 in) of X travel against 30 in (762 mm)
Haas VF-2SS Super Speed VMC
- 12,000 rpm spindle against 8,000 rpm
- 30 hp (22.4 kW) spindle power against 18.5 kW (25 hp)
- 1,500 lb (680 kg) table load against 600 kg (1,323 lb)
Verdict
Choose the Haas VF-2SS Super Speed VMC for aluminum parts and small tools, where 12,000 rpm and 30 hp (22.4 kW) set the cycle time. Choose the Doosan DNM 4500 when the part or fixture is wide: it has 450 mm (18 in) of Y and a 1,000 × 450 mm (39 × 18 in) table, and for general steel and aluminum job-shop work its 8,000 rpm spindle is enough. Rapids and Z travel do not separate them.
