Overview

The DN Solutions DNM 6700 L is the long-bed variant of the DNM 6700, stretching X-axis travel to 1,500 mm (59 in) for shops that need to machine longer parts without compromising on the 6700's generous Y and Z capacity. You're getting 1,500 x 670 x 625 mm of travel with a 1,600 x 670 mm table that handles workpieces up to 1,300 kg — that covers a huge range of mid-to-large production work.

The spindle runs the standard DNM powertrain: ISO 40 taper, 8,000 RPM, 18.5 kW (25 hp), 117.8 Nm torque. It's not flashy, but it's proven across tens of thousands of installations. The box-way construction matters even more on an extended-travel machine like this — linear guides can lose rigidity at the extremes of long travels, while properly tuned box ways maintain cutting performance edge to edge.

At 9,000 kg, the DNM 6700 L carries more mass than the standard 6700's 8,500 kg, reflecting the longer bed casting. That extra weight helps dampen vibration across the entire travel range, particularly when machining at the far ends of the X-axis where lighter machines tend to chatter. The 1,600 x 670 mm table gives you room to fixture multiple parts side by side or handle single workpieces up to about 60 inches long.

This is the machine for shops doing long structural components, multiple-part fixturing, and production runs where you want to fill the table with parts and let it run. Aerospace beam sections, automotive subframes, and long mold bases all fit naturally on this platform.

Strengths & Limitations

Strengths

1,500 mm X-axis travel handles long parts that won't fit on standard VMCs — up to 60 inches of workpiece length
625 mm Z-axis travel provides deep reach for tall parts and cavity work, a meaningful upgrade over the 5700 series
9,000 kg machine weight maintains cutting rigidity even at extreme X-axis positions where lighter machines chatter
1,300 kg table capacity supports heavy fixtures and multiple-part setups for production efficiency
Box-way construction performs consistently across the full travel range without rigidity loss at the ends
Standard DNM platform with massive parts and service infrastructure worldwide

Limitations

Large footprint demands significant floor space — measure twice before committing to the long-bed variant
8,000 RPM spindle speed is conservative for aluminum-heavy shops needing high surface speeds
9,000 kg weight requires reinforced concrete foundation and makes relocation difficult
30-tool standard magazine may need upgrading for complex multi-operation parts

Best For

Aerospace shops machining long beam sections, stringers, and structural members that need 50+ inches of X-travel Mold shops working with long mold bases and large core/cavity blocks that exceed standard VMC table lengths Production shops fixturing multiple parts side by side to maximize spindle utilization per cycle Automotive suppliers machining subframes, crossmembers, and other long structural components Job shops that frequently see long parts and want one machine to handle them without creative fixturing

Frequently Asked Questions

01 What does a DN Solutions DNM 6700 L cost?

Expect $120,000-$165,000 new depending on spindle option and accessories. The L variant adds roughly $10,000-$15,000 over the standard DNM 6700 for the extended bed. Used Doosan-era models sell in the $45,000-$80,000 range.

02 How does the DNM 6700 L compare to the DNM 6700 XL?

The XL stretches X-travel further to 2,100 mm (83 in) with a 2,200 mm table, adding another 600 mm of reach for even longer parts. The XL weighs 10,000 kg versus the L's 9,000 kg. Choose the XL only if you genuinely need 80+ inch parts — the L covers most long-part work at a lower price and smaller footprint.

03 Is the DNM 6700 L good for multiple-part fixturing?

Absolutely. The 1,600 x 670 mm table with 1,300 kg capacity is ideal for gang fixturing. You can run two or three identical parts in a row, or fixture different operations on the same plate. The 1,500 mm X-travel gives the spindle full access across a multi-station setup.

04 What floor preparation does the DNM 6700 L need?

At 9,000 kg, you'll need a minimum 6-inch reinforced concrete slab. DN Solutions provides a foundation drawing with point-load specifications. The machine uses leveling pads rather than anchor bolts, but the slab needs to be flat and rated for the distributed weight.
