Built for Large Part Machining with Unmatched Rigidity

The DNM 6700 4th Gen delivers expanded capacity and high torque performance for heavy-duty vertical machining. With X/Y/Z travels of 1,300 × 670 × 625 mm, this model supports large workpieces and extended fixtures with ease. The massive Meehanite cast iron bed, rigid box-type column, and roller-type linear guideways ensure structural rigidity under the most demanding cutting conditions.

Ideal for job shops, aerospace suppliers, and mold/die manufacturers, the DNM 6700 combines power, accuracy, and reliability in a machine designed for large-part productivity.

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.
