Doosan Machine Tools vs Doosan Machine Tools · Vertical Machining Centers
Summary
The Doosan DNM 5700 and Doosan DNM 6700 are two sizes of the same vertical machining center family. They share an 8,000 rpm spindle rated 18.5 kW (25 hp) with 117.8 N·m (87 ft-lb) of torque, and both rapid at 36 m/min (1,417 ipm). The difference is the envelope.
The DNM 6700 travels 1,300 x 670 x 625 mm against 1,050 x 570 x 510 mm, carries a 1,500 × 670 mm table against 1,300 × 570 mm, and is rated for 1,300 kg (2,866 lb) of workpiece against 1,000 kg (2,205 lb). The DNM 5700 is the smaller and lighter machine: 6,500 kg (14,330 lb) against 8,500 kg (18,739 lb), on a 2,413 × 3,100 mm footprint against 2,597 × 3,350 mm.

Advantages
Doosan DNM 5700
- Smaller footprint: 2,413 × 3,100 × 2,985 mm against 2,597 × 3,350 × 3,120 mm
- Lighter machine at 6,500 kg (14,330 lb) against 8,500 kg (18,739 lb)
Doosan DNM 6700
- 1,300 mm (51 in) of X travel against 1,050 mm (41 in)
- 670 mm (26 in) of Y and 625 mm (25 in) of Z against 570 mm (22 in) and 510 mm (20 in)
- 1,500 × 670 mm table rated for 1,300 kg (2,866 lb) against 1,300 × 570 mm and 1,000 kg (2,205 lb)
Verdict
The spindle, torque and rapids are identical, so buy on part size. The Doosan DNM 5700 suits shops whose plates and multi-vise setups fit within 1,050 mm of X and 1,000 kg, and that want the smaller footprint. The Doosan DNM 6700 is the choice for mold bases up to 1,300 kg, tall setups that need 625 mm of Z, and long parts or rows of fixtures across 1,300 mm of X.
