Advantages
Doosan DNM 4500
- Lighter at 5,000 kg (11,023 lb) against 6,500 kg (14,330 lb)
- Smaller footprint: 2,158 × 2,615 mm against 2,413 × 3,100 mm
Doosan DNM 5700
- 1,050 mm (41 in) of X travel against 800 mm (31 in)
- 570 mm (22 in) of Y travel against 450 mm (18 in)
- 1,300 × 570 mm (51 × 22 in) table against 1,000 × 450 mm (39 × 18 in)
- 1,000 kg (2,205 lb) table load against 600 kg (1,323 lb)
Verdict
Since the spindle and rapids are identical, buy on part size. The Doosan DNM 5700 is the choice for multi-vise setups along its 1,300 mm (51 in) table, mold bases and plates up to 1,000 kg (2,205 lb), or parts that need 570 mm (22 in) of Y travel. The Doosan DNM 4500 is the choice for vise work and small fixtures when floor space is tight and parts stay under 600 kg (1,323 lb).
