DNM 5700 4th Generation: Vertical Machining Center for Large, Heavy-Part Production

The DNM 5700 4th Generation is a vertical machining center built for shops that need to hold tolerance on large, heavy parts without slowing down production. It delivers 1,050 x 570 x 510 mm of X, Y, and Z travel across a 1,300 x 570 mm table rated for 1,000 kg, with a choice of an 8,000 rpm high-torque spindle or a 15,000 rpm high-speed spindle depending on the work. Ellison Technologies, the largest DN Solutions distributor in North America, stocks and supports the full DNM lineup for shops matching table size and spindle configuration to their part mix.

DN SOLUTIONS (FORMERLY DOOSAN MACHINE TOOLS) DNM VERTICAL MACHINING CENTER ALL-PURPOSE PRODUCTION

Work smarter, not harder. The DN Solutions (formerly Doosan Machine Tools) DNM 5700 vertical machining center comes packed with the most production improving standard features to keep you one step ahead of the competition. Enhanced FANUC controls, pre-wired Renishaw probing, dual screw chip auger, through spindle coolant, spindle chiller, and Big Plus spindle to name a few.

Aerospace and Structural Components

Aerospace shops running structural brackets, housings, and large fixtures benefit from the DNM 5700 4th Gen's 1,300 x 570 mm table and 1,000 kg load capacity, which accommodate oversized aluminum and titanium parts without a second setup. The 15,000 rpm high-speed spindle keeps cycle times down on aluminum structural work, while the standard 8,000 rpm, 286 Nm high-torque spindle covers heavier titanium and steel cuts on the same machine. Ellison supports aerospace manufacturers across its territory with machines sized for these part families.

Energy and Heavy Industry

Energy sector parts, manifolds, housings, and structural components for oil and gas or power generation equipment, tend to be large, heavy, and need repeatable accuracy across a wide table. The DNM 5700 4th Gen's 1,000 kg table load and reinforced saddle design support these heavier workpieces without giving up positioning accuracy. Ellison serves energy and oil and gas manufacturers with machines built to handle this class of part.

Mold, Die, and Large Tooling

Mold and die shops need a machine that holds tolerance across a large work envelope during long, unattended cuts. The DNM 5700 4th Gen's Meehanite cast-iron bed and oversized linear roller guides are built for that kind of extended cutting, and Smart Thermal Monitoring compensates for spindle heat during long production runs, which matters most on jobs where a single setup can run for hours. The 30-tool standard ATC, expandable to 40 or 60, keeps a full roughing-to-finishing tool set on the machine for large mold and die work.

Medical Equipment Components

Some medical equipment manufacturers use the DNM 5700 4th Gen for larger components, such as imaging equipment housings, surgical robotic bases, and equipment frames, where the priority is a large work envelope and reliable repeatability rather than micro-part tolerances. Through-spindle coolant and an optional air-through-spindle setting keep the cut clean on materials where contamination is a concern. Ellison works with medical equipment manufacturers who need this kind of large-format capacity.

Versatile Spindle Options: Torque or Speed

Choose between two powerful spindle configurations:

8,000 RPM high-torque spindle: 286 Nm (211 ft-lbs), 15/20 hp—ideal for hard metal removal
15,000 RPM high-speed spindle: 118 Nm (87 ft-lbs), 25 hp—perfect for precision contouring and mold work

Both spindles feature Big Plus CAT40 tooling and are oil-jacket cooled for thermal stability. Spindle acceleration and deceleration are tightly controlled, optimizing productivity while minimizing wear. Rigid tapping and through-spindle coolant come standard, ensuring better chip evacuation and part finish at higher feedrates.

Expandable Tooling and Intelligent Automation

The servo-driven double-arm ATC supports 30, 40, or 60 tools, each up to 300 mm long and 8 kg in weight. Chip-to-chip tool change time is just 4.1 seconds, improving cycle efficiency. Combined with Renishaw probe readiness, adaptive feedrate control, and tool load monitoring, the DNM 5700 is automation-ready—ideal for high-mix, low-touch environments. Smart features like manual pulse generator, full guarding, and large sliding doors simplify operator interaction and maintenance.

Smart Thermal and Load Control for Accuracy

Ellison’s DNM 5700 integrates Smart Thermal Monitoring, a sensorless algorithm that proactively compensates for spindle heat expansion. Combined with high-rigidity ball screws and roller guides, the system ensures micron-level repeatability during extended runs. Meanwhile, the Tool Load Monitoring System protects against tool breakage and wear, reducing unplanned downtime and improving tool utilization.

FAQ Section

What’s the difference between the 8K and 15K spindle options?

The 8,000 RPM high-torque spindle delivers up to 286 Nm of torque—ideal for heavy-duty cutting and harder metals like steel and cast iron. The 15,000 RPM spindle offers high-speed precision, better suited for aluminum, plastics, or complex 3D contouring in mold and die work. Your choice depends on part material, surface finish goals, and machining strategies.

How does the DNM 5700 improve thermal stability?

The machine uses a spindle oil chiller and software-based Smart Thermal Monitoring system to actively reduce thermal drift. Instead of relying on sensors, the algorithm compensates based on RPM and cycle duration—improving part accuracy during long or continuous jobs. This is especially valuable in aerospace and mold manufacturing, where tight tolerances are critical.

Is this machine automation-ready?

Yes. The DNM 5700 includes standard features that enable easy automation:

Probe-ready with Renishaw OMI-2T
Through-spindle coolant and air
Full enclosure with large access doors
Chip conveyors, tool load monitoring, and grease lubrication

These make it suitable for pallet systems, robotic loading, or lights-out manufacturing environments.

Can the ATC handle long or heavy tools?

Yes. The automatic tool changer supports tools up to 300 mm (11.8") long, 8 kg (17.6 lb) in weight, and up to 125 mm diameter (when adjacent pockets are empty). Options for 40- or 60-tool magazines allow greater flexibility in complex jobs or multi-material production lines.

What industries is the DNM 5700 built for?

This model is engineered for aerospace, die/mold, energy, medical, and general precision machining. Its rigidity, expanded travels, and thermal compensation features make it perfect for shops needing high mix, medium volume production with minimal setup time.
