High-Speed Machining Without Compromise

The DNM 5700S 4th Gen is the high-speed variant of the trusted DNM 5700 platform, equipped standard with a 15,000 RPM direct-drive spindle designed for rapid material removal and superior surface finishes. With its large working envelope—X/Y/Z travels of 1,050 × 570 × 510 mm—and a rugged build designed for consistent precision, the 5700S is an ideal fit for mold & die shops, aerospace suppliers, and medical device manufacturers looking to reduce cycle times without sacrificing accuracy.

Superior Thermal Stability and Motion Control

To maintain tolerances during extended machining cycles, the DNM 5700S includes:

  • Smart Thermal Monitoring: Predicts spindle heat drift and compensates algorithmically

  • Oil-jacketed spindle cooling: Maintains thermal balance during high-speed operation

  • Wide roller-type linear guideways: Support heavier cutting loads with smooth axis movement

  • Pre-tensioned ball screws: Eliminate backlash and boost repeatability

These features ensure the machine performs predictably across all three axes, even in lights-out or high-volume environments.

Fast Tool Changes and Automation Readiness

The DNM 5700S supports:

  • 30-tool servo-type ATC standard (options for 40 or 60 tools)

  • Tool-to-tool change time: 1.2 seconds

  • Chip-to-chip change time: 4.1 seconds

  • Max tool size: 125 mm diameter (with adjacent pots empty), 300 mm length, 8 kg

It’s also Renishaw OMI-2T probe-ready, enabling in-process part inspection and tool measurement. Coupled with adaptive feedrate control, tool load monitoring, and high-pressure through-spindle coolant, the 5700S is purpose-built for unattended high-speed production.

Designed for Production Efficiency

The DNM 5700S boasts:

  • 1,000 kg (2,205 lb) table load capacity

  • 15″ iHMi touchscreen control with FANUC 0i-Plus CNC

  • Grease lubrication system for low-maintenance operation

  • Fully enclosed guarding, telescopic covers, and flood/through-spindle coolant for chip and coolant containment

Its compact 2,470 × 3,320 mm footprint fits comfortably on most shop floors while still delivering extended axis travels.

FAQ Section

What makes the DNM 5700S different from the standard DNM 5700?

The DNM 5700S comes standard with a 15,000 RPM high-speed spindle, compared to the 8K or optional 15K spindle on the base model. This makes the 5700S ideal for high-speed cutting, surface finishing, and mold/die applications where reduced cycle time and high RPMs are critical. All other platform specs—rigid casting, roller guides, tool changer, and automation features—remain the same, ensuring you don’t trade durability for speed.

Is the DNM 5700S suitable for aluminum and composite machining?

Yes. Its high spindle speed and thermal stability make it particularly effective for materials like aluminum, carbon fiber, plastics, and other light alloys. The machine’s through-spindle coolant, high RPMs, and vibration-dampened construction help achieve excellent surface finishes without sacrificing feedrate or tool life.

How does the Smart Thermal Monitoring system work?

Rather than relying on physical temperature sensors, the DNM 5700S uses algorithmic models based on spindle speed and usage time to predict thermal expansion. It automatically compensates for drift by adjusting axis positioning, maintaining micron-level precision even during long or heat-intensive machining cycles.

Can the tool changer be expanded for high-mix production?

Yes. The standard 30-tool ATC can be upgraded to 40 or 60 tools, allowing the machine to support more part variations, reduce tool setup time, and keep spindle utilization high in job shops or automated cells. Each magazine supports tools up to 300 mm in length and 8 kg in weight.

What industries benefit most from the 5700S?

The DNM 5700S is tailored for aerospace, die/mold, medical device, energy, and automotive industries—anywhere precision and surface finish are just as important as cycle time. It’s especially effective for high-speed finishing operations or intricate part geometry where RPM and axis responsiveness matter.
