Overview

The Doosan DNM 6700 is the large-format CNC vertical machining center in Doosan's DNM series, extending the platform to a 1,300 x 670 mm (51.2 x 26.4 in) table — one of the largest table capacities in the standard 40-taper VMC class. The DNM 6700 targets the large workpiece segment where shops need VMC-class accessibility and programming simplicity for large mold plates, aerospace structural panels, large fixture plates, and large-format production components that exceed the capacity of mid-size VMCs.

The DNM 6700's 30-tool ATC and 15,000 RPM (18,500 RPM option) spindle provide the tool capacity and speed range for complex programs requiring many tool changes and spindle speed variation across roughing and finishing operations on large workpieces. The machine's 15,000-lumen LED work light system (a Doosan standard feature on DNM 6700) improves chip visibility in the large machining envelope — a practical detail often missed in spec comparisons.

For mold shops, the DNM 6700 handles large mold frame machining, large cavity rough milling, and electrode holder machining in the wide-open VMC format that gives operators complete visual access and easy manual fixturing of large workpieces. The 1,300 mm X-travel accommodates mold bases up to approximately 1,200 mm in X — covering most single-cavity automotive bumper and dashboard molds, large packaging molds, and appliance molds.

At $140,000-$200,000, the DNM 6700 is competitively priced against the Haas VF-6 and Mazak VCN-700 in the large-format VMC segment, with Doosan's typical 15-20% price advantage for comparable specifications.

Strengths & Limitations

Strengths

1,300 x 670 mm table handles large mold frames, aerospace panels, and large fixture plates that require refixturing on smaller VMCs
30-tool ATC provides sufficient tool capacity for complex programs requiring roughing, semi-finishing, and finishing tool sets
22 kW spindle delivers aggressive stock removal on large aluminum and steel workpieces at 15,000 RPM
Price advantage over Haas VF-6 equivalent — typically 15-20% lower for comparable specifications
Standard LED work light system improves chip visibility in the large machining envelope

Limitations

BT40/CAT40 taper standard — shops needing CAT50 rigidity for very heavy large-part cuts should consider HMC platforms
10,500 kg machine weight requires solid floor foundation — site prep is significant for some facilities
Doosan's service coverage is less dense than Haas or Mazak in remote North American locations
Large table footprint means the machine requires significant floor space in the shop

Best For

Mold shops rough-milling large mold frame cavities and performing electrode holder machining on large-format molds Aerospace subcontractors machining large structural panel fixtures, jig components, and tooling plates Die shops machining large stamping die shoes and punch holder plates that exceed 1,000 mm in X Job shops seeking large-table VMC capacity at competitive pricing for mixed large-part production work Shops requiring a large VMC with familiar Fanuc control for programming continuity with existing machines

Frequently Asked Questions

01 How does the DNM 6700 compare to the Haas VF-6?

The DNM 6700 and Haas VF-6 have similar table sizes and spindle specifications. The Haas VF-6 benefits from Haas's own nationwide service network and excellent parts availability. The Doosan DNM 6700 typically prices 15-20% lower and offers comparable core specs. For shops with Doosan dealer coverage in their region (Ellison Technologies, Methods Machine Tools), the DNM 6700 represents strong value. Shops in areas without local Doosan coverage may prefer the Haas for service accessibility.

02 Is the DNM 6700 suitable for mold rough machining?

Yes. The DNM 6700's 1,300 mm X-travel and 22 kW spindle make it well-suited for rough milling large mold cavity blocks in P20 pre-hardened tool steel and aluminum mold plate. The boxway option adds rigidity for heavy roughing cuts. However, for finishing hardened mold cavities (50+ HRC), shops typically pair the DNM 6700 for roughing with a dedicated high-speed machining center (Makino, Röders, Fanuc Robodrill) for finish milling.

03 What is the maximum workpiece weight on the DNM 6700 table?

The DNM 6700 has a standard table load capacity of 1,000 kg (2,205 lb) distributed across the full table surface. For heavy workpieces approaching this limit, ensure that the fixture is distributed across the full table span to avoid concentrated loading on the table center. Exceeding this capacity will affect positioning accuracy and can damage the table and guideway system.
