Overview

The Doosan DNM 6700 is a large-travel vertical machining center from DN Solutions (formerly Doosan Machine Tools), featuring 1,320mm X-axis travel designed for medium-to-large workpiece production in a single setup. As one of the largest models in the DNM series, the 6700 targets aerospace structural components, mold and die, energy sector parts, and heavy industrial components that exceed the capacity of standard 1,000mm-class VMCs. Built on a high-rigidity cast iron column and bed with linear guide construction, the DNM 6700 combines a large work envelope with high rapid traverse rates and a capable 12,000–15,000 RPM spindle for versatile cutting across aluminum, steel, stainless, and titanium.

The DNM 6700's table — 1,700 x 700 mm — accommodates substantial workpieces and allows multiple fixture setups for batch machining of smaller parts or single-setup machining of long structural components. The machine's linear guide system on all axes enables rapid traverse rates up to 48 m/min, maintaining productive positioning times despite the large travel distances. Spindle power of 22–30 kW provides both the low-end torque for steel roughing and high-speed power for aluminum finishing without requiring tool-change spindle swaps.

DN Solutions equips the DNM 6700 with the Fanuc 0iMF Plus control as standard, with Heidenhain iTNC 640 available for European mold and die applications. Full enclosure, programmable coolant, and chip conveyor integration support production environments. Through-spindle coolant at high pressure is available as an option for deep-pocket drilling and high-speed steel milling. The machine's column design and bed casting are engineered for thermal stability in sustained production cycles.

The DNM 6700 competes with the Mazak VCN-700C, Okuma MB-10000H (as a horizontal alternative), and Hyundai WIA F660D in the large-travel production VMC class. New machine pricing typically ranges from $180,000 to $280,000. For shops requiring 1,300mm-class X-axis travel with DN Solutions' established service infrastructure and Fanuc control, the DNM 6700 is a well-proven production choice.

Strengths & Limitations

Strengths

1,320mm X-axis travel and 1,700 x 700mm table handle large aerospace structures, long mold bases, and multi-fixture production setups that exceed the capacity of standard 1,000mm-class VMCs
2,000 kg table load rating accommodates heavy steel fixtures, large cast iron workpieces, and dense part-and-fixture combinations without overloading the linear guide system
DN Solutions' extensive North American and European dealer and service network provides installation support, application engineering, and parts availability that supports high-uptime production operation
No. 50 taper spindle provides the rigidity and torque capacity needed for heavy roughing in steel and titanium that No. 40 taper machines cannot match at equivalent cutting parameters

Limitations

No. 50 taper tooling is larger and heavier than No. 40, limiting spindle RPM headroom and increasing tooling inventory cost for shops that also run No. 40 machines — less ideal for pure high-speed aluminum work
Premium pricing ($180,000–$280,000) is justified by large-part capability but exceeds the budget appropriate for shops whose work rarely uses more than 1,000mm X-axis travel
Large machine footprint (approximately 6,500 x 3,500 mm) requires significant floor space and careful shop layout planning, particularly for shops adding to an existing machine line

Best For

Aerospace structural component manufacturers machining large aluminum and titanium frames, spars, bulkheads, and panels in the 1,200–1,300mm length range in a single setup Mold and die shops producing large injection mold bases, die casting dies, and stamping dies that require 1,300mm X-axis capacity and heavy-cut No. 50 taper spindle capability Energy sector manufacturers machining large valve bodies, pump casings, turbine housings, and other structural components requiring the full 1,320mm work envelope Heavy industrial job shops serving multiple industries who need a large-capacity general-purpose VMC with DN Solutions' service infrastructure for maximum uptime on high-value parts

Frequently Asked Questions

01 What is the DNM 6700's relationship to the broader DN Solutions DNM series?

The DNM series is DN Solutions' (formerly Doosan) core production VMC lineup, covering machines from the DNM 4000 (smaller travel) through the DNM 6700 (largest standard travel) and beyond. The 6700 designation indicates the 670mm Y-axis travel, with the full model designation referencing X, Y, and Z capacity in the series convention. The DNM 6700 is the large-capacity workhorse of the series, positioned for shops whose work consistently requires 1,000mm+ X-axis capacity.

02 Can the DNM 6700 machine titanium aerospace components?

Yes. The DNM 6700's No. 50 taper spindle and 22–30 kW power provide the rigidity and torque required for titanium machining. Key considerations for titanium include using appropriate cutting parameters (conservative speeds and feeds versus aluminum), sharp carbide tooling with positive geometry, and high-flow coolant to manage heat. The DNM 6700's through-spindle coolant option is recommended for titanium deep-pocket and drilling operations to maintain tool life and chip evacuation.

03 What is the difference between the 30-tool and 60-tool ATC configurations?

The standard DNM 6700 ships with a 30-tool arm-type ATC. The optional 60-tool magazine is a chain-type or matrix configuration that accommodates complex programs requiring large tool libraries — common in aerospace, mold, and multi-feature production programs. Shops with programs consistently using more than 25–28 tools should specify the 60-tool option during the purchase process. The larger magazine may affect overall machine footprint and lead time.

04 Is the Heidenhain iTNC 640 control a significant upgrade from the Fanuc 0iMF Plus?

The Heidenhain iTNC 640 offers different strengths than the Fanuc 0iMF Plus, particularly for 3D contouring, DXF import, and mold machining applications where Heidenhain's conversational programming and contouring cycles excel. For shops already standardized on Fanuc with existing post processors and operator familiarity, the Fanuc 0iMF Plus is the lower-risk choice. Mold shops and shops with European machining traditions often prefer Heidenhain. Both are capable controls — the choice depends on existing shop infrastructure and application requirements.

05 How does the DNM 6700 compare to the Mazak VCN-700C?

Both machines compete in the large-travel production VMC class with similar X-axis travel and No. 50 taper spindles. The Mazak VCN-700C runs the Mazatrol SmoothG control with strong conversational programming and Mazak's Multi-Tasking G-code library, while the DNM 6700 uses Fanuc 0iMF Plus. Mazak's dealer network in North America is broader, but DN Solutions has a strong established presence. Both machines are well-proven production platforms — the decision often comes down to existing brand relationships and control preference.
