Overview

The DN Solutions DNM 750L II stretches the already-large DNM 750 platform to an extraordinary 2,160 mm (85 in) of X-axis travel. This is the longest-travel machine in the entire standard DNM lineup, built for shops that need to machine very long parts on a vertical platform without stepping up to a double-column or gantry machine. Combined with 762 mm Y and 650 mm Z travel, you've got a work envelope that handles parts most VMCs can't even fixture.

The spindle delivers 118 Nm through an ISO 40 taper at 8,000 RPM. At this table size, the 40-taper makes sense — you're likely doing lighter passes across long surfaces rather than heavy hogging in a small area. The table measures 2,160 x 760 mm with an 1,800 kg load capacity, which is the highest in the standard DNM range. That capacity matters because long parts and multi-station fixtures add up weight quickly.

At 15,000 kg, the DNM 750L II is the heaviest standard DNM you can buy. Every kilogram of that mass contributes to vibration damping across the 2.16-meter travel range. Box-way construction maintains consistent cutting feel from one end of the table to the other, though shops should understand that any C-frame machine at 85 inches of X-travel has inherent overhang limitations at the extremes.

This machine fills a specific niche: shops that need very long linear travel but don't have the budget or floor space for a double-column platform. Aerospace stringers, long mold bases, structural beams, and multi-part production layouts all benefit from having 85 inches of continuous X-axis motion under CNC control.

Strengths & Limitations

Strengths

2,160 mm X-axis travel is the longest in the standard DNM range — machines parts up to 85 inches without creative fixturing
1,800 kg table capacity is the highest in the DNM family, handling heavy long parts and loaded multi-station fixtures
15,000 kg machine weight provides massive vibration damping across the full extended travel range
762 mm Y and 650 mm Z travel mean you're not just getting length — full 3D capability on long parts
40-taper platform keeps tooling costs manageable compared to 50-taper alternatives at this size
Box-way construction maintains consistent cutting performance across 2.16 meters of X-motion

Limitations

C-frame design at 2,160 mm X-travel has inherent overhang at the extremes — not ideal for heavy cuts at the far end
15,000 kg weight requires serious foundation work — minimum 8-10 inch reinforced slab recommended
Enormous footprint limits placement flexibility and practically eliminates relocation as an option
118 Nm spindle torque through ISO 40 is modest for heavy steel work at this machine size
8,000 RPM limits high-speed applications even on a machine this size

Best For

Aerospace shops machining long stringers, spar caps, and structural members that need 80+ inches of continuous X-travel Mold base manufacturers working with oversized bases that exceed the X-travel of standard VMCs Production shops running multi-station fixture layouts across the 2,160 mm table for maximum spindle utilization Structural component manufacturers machining long beams, rails, and architectural elements Shops that need long-travel VMC capability but can't justify the cost of a double-column or gantry platform

Frequently Asked Questions

01 What does a DN Solutions DNM 750L II cost?

New pricing runs $160,000-$220,000 depending on options. That's roughly $30,000-$40,000 more than the standard DNM 750 II for the extended bed. Used Doosan-era models are rare on the secondary market but sell for $65,000-$110,000 when available.

02 Should I get the DNM 750L II or a double-column machine?

A double-column machine provides better rigidity at every point across a large table because the spindle never overhangs the column. The DNM 750L II costs significantly less and has a smaller footprint. For finishing passes and moderate-depth cuts on long parts, the 750L II works well. For heavy roughing across the full table, a double-column is the better choice.

03 How does the DNM 750L II compare to the DNM 6700 XL?

The 750L II has more X-travel (2,160 vs 2,100 mm), more Y-travel (762 vs 670 mm), more Z-travel (650 vs 625 mm), and higher table load (1,800 vs 1,300 kg). It weighs 15,000 kg versus 10,000 kg. The 750L II is the larger, heavier machine for bigger and heavier parts. The 6700 XL costs less and has a smaller footprint.

04 Is the 40-taper spindle limiting on a machine this size?

For heavy steel roughing with large-diameter cutters, yes — the 118 Nm torque limits how hard you can push. For most mixed-material work and multi-station production, 40-taper is practical and keeps tooling costs down. If your work is primarily heavy steel on big parts, consider the 50-taper DNM 750 50 II instead.
