DNM 6700 4th Gen Vertical Machining Center for Large-Part Production

The DNM 6700 4th Gen is DN Solutions' large-capacity vertical machining center, built for shops that need to hold tolerance on oversized parts. It delivers 1,300 x 670 x 625 mm of X/Y/Z travel, a 1,300 kg table load capacity, and a choice of 8,000 rpm high-torque or 15,000 rpm high-speed spindle options. It's part of Ellison's broader machining centers lineup. Ellison Technologies, the authorized DN Solutions distributor across a large multi-state territory and serving manufacturers since 1955, stocks and services the DNM 6700 4th Gen for aerospace, automotive, and energy shops running large-format work.

Aerospace and Structural Components

Aerospace suppliers use the DNM 6700 4th Gen to machine large structural brackets, housings, and fixtures that need multiple setups on smaller machines. The 1,300 mm X-axis travel and 1,300 kg table load handle oversized aluminum and titanium workpieces in a single fixture, and Smart Thermal Monitoring keeps positioning accuracy inside 0.014 mm through long production runs. Ellison Technologies supports aerospace manufacturers across its territory with machine setup, spindle rebuild, and ongoing service.

Automotive and Heavy Equipment

Automotive and heavy-equipment shops run the DNM 6700 4th Gen on large tooling, jigs, and structural components that outgrow standard-size VMCs. The 8,000 rpm high-torque spindle option cuts steel and cast iron efficiently, and the 30-tool ATC, expandable to 60, keeps multi-operation jobs running without manual intervention. Ellison works with automotive manufacturers throughout its DN Solutions territory to spec, install, and maintain machines like the DNM 6700.

Energy and Oil & Gas

Energy and oil & gas manufacturers use large-envelope VMCs like the DNM 6700 4th Gen to machine valve bodies, manifolds, and other heavy components that need a rigid, well-supported table. The machine's 1,300 kg load capacity and fully supported saddle, with no table overhang, hold accuracy on unbalanced, asymmetric parts. Ellison Technologies serves energy and oil & gas manufacturers with the DNM 6700 and the rest of its DN Solutions lineup.

Performance-Driven Features That Maximize Output

The DNM 6700 4th Gen offers a choice between:

8,000 RPM high-torque spindle: 286 Nm (211 ft-lbs)
15,000 RPM high-speed spindle: 118 Nm (87 ft-lbs)

Key capabilities include:

Big Plus CAT 40 spindle with rigid tapping
Direct-drive spindle with oil-jacket chiller for thermal control
Rapid traverse speeds: 36 m/min (X/Y), 30 m/min (Z)
Adaptive Feedrate Control & Tool Load Monitoring
Renishaw probe-ready with OMI-2T optical interface

The intelligent design supports dynamic machining strategies while maintaining micron-level accuracy over long production cycles.

Automation-Ready for High-Mix, High-Volume Workflows

Engineered for production efficiency, the DNM 6700 includes:

30-tool ATC standard (options for 40 or 60 tools)
Tool-to-tool time: 1.2 seconds
Chip-to-chip time: 4.4 seconds
Max tool length: 300 mm (11.8"), up to 8 kg (17.6 lb)

Spindle options, advanced coolant delivery (through-spindle and air), and a programmable MPG control make it simple to integrate into a lights-out or hybrid production environment.

Designed for Precision and Longevity

The DNM 6700 was built for long-term accuracy with:

Smart Thermal Monitoring: Compensates for heat-based drift in real time
Eco-friendly grease lubrication: Lower maintenance, cleaner operation
ISO 230-2 compliant: Positioning accuracy of ±0.014 mm and repeatability of ±0.007 mm

Additional specs:

Table load capacity: 1,300 kg (2,866 lb)
Machine footprint: 2,670 × 3,560 mm
Machine weight: 8,500 kg (18,739 lb)

This combination of rigid construction and intelligent controls ensures long-term precision across all types of materials and part geometries.

FAQ Section

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

The 8,000 RPM spindle is designed for high-torque, heavy-duty cutting with a peak torque of 286 Nm, making it ideal for steel and hard materials. The 15,000 RPM spindle offers higher rotational speed at 118 Nm torque, optimized for high-speed finishing, aluminum cutting, and mold/die work. Choose based on your material mix and desired surface finish.

Is the DNM 6700 suitable for large part machining?

Yes. With a 1,300 mm X-axis travel and 1,300 kg table load capacity, the DNM 6700 is ideal for large components, fixtures, and dies. The fully supported saddle and wide roller guides prevent overhang and maintain part accuracy regardless of weight distribution.

How does Smart Thermal Monitoring improve accuracy?

Smart Thermal Monitoring is a sensorless software algorithm that detects spindle thermal behavior based on spindle speed and runtime. It automatically compensates for thermal expansion, maintaining precision over long shifts or in changing environments—ideal for shops running tight tolerance production.

Can this machine handle automation or unattended machining?

Absolutely. The DNM 6700 features Renishaw probing, adaptive feedrate control, and tool load monitoring. It’s compatible with robotic load/unload systems and high-capacity tool changers (up to 60 tools), making it suitable for high-mix or high-volume lights-out environments.

What industries benefit most from the DNM 6700?

Industries such as aerospace, die/mold, automotive, and energy benefit from the DNM 6700’s combination of capacity, power, and precision. It’s especially valuable when machining large steel or alloy parts requiring multi-axis stability and repeatable tolerances.
