DNM 5700L 4th Generation: Long X-Travel Vertical Machining Center for Large Parts

The DNM 5700L 4th Generation is a vertical machining center built for shops that need extra-long X-axis travel without giving up rigidity. It delivers 1,300 mm of X travel across a 1,500 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 running oversized parts, fixtures, or high-density multi-part setups.

DNM 5700L 4th Generation Applications and Industries

Aerospace and Structural Components

Aerospace shops use the DNM 5700L 4th Generation to machine large structural parts and brackets that need a big table and consistent thermal behavior across long cycles. The machine's Smart Thermal Monitoring system compensates for spindle growth during extended runs, and the 15,000 rpm spindle handles aluminum structural work while the 8,000 rpm high-torque spindle covers titanium and harder alloys. Ellison supports aerospace manufacturers across its territory with the tolerances and duty cycles this kind of work requires.

Energy and Heavy Industry

Energy and heavy-industry parts such as manifolds, housings, and large fabricated components often exceed the table size of a standard VMC, which is why the DNM 5700L 4th Generation's 1,500 x 570 mm table and 1,000 kg load rating matter. The 8,000 rpm, 286 Nm high-torque spindle is built for the heavier cuts this work demands. Ellison works with energy and oil and gas manufacturers who need a machine that holds tolerance through a full shift of roughing and finishing on large stock.

Mold, Die, and Large Tooling

Mold and die shops need a machine that holds precision across a large work envelope without losing surface finish as the spindle heats up. The DNM 5700L 4th Generation's roller-type linear guideways and direct-coupled spindle keep vibration low, and Renishaw probe readiness (OMI-2T optical receiver) supports in-process alignment on large tooling blocks. Between the 30, 40, and 60-tool ATC options, shops can run complex die work without stopping for manual tool changes.

Intelligent Features for Lights-Out Machining

The DNM 5700L comes standard with:

  • Smart Thermal Monitoring: Predicts spindle heat drift and applies compensation

  • Adaptive Feedrate Control: Adjusts feed in real-time based on spindle load

  • Tool Load Monitoring: Detects wear or breakage to prevent scrap or downtime

  • Renishaw OMI-2T probe readiness: For in-process part and tool measurement

With up to 60-tool automatic tool changers, through-spindle coolant/air, and high-pressure flood coolant, this machine is built for automation, consistency, and 24/7 performance.

Built-In Stability and Longevity

The 5700L’s frame features 8-point leveling and a thicker, ribbed saddle for vibration damping. Its roller-type linear guideways are wider and more rigid than ball-type guides, ensuring high-accuracy machining even over long runs. The direct-coupled ball screws and servo-mounted drives eliminate backlash and deliver fast rapid traverse rates:

  • X/Y: 42 m/min

  • Z: 36 m/min

Whether machining aerospace structures, energy components, or production dies, the DNM 5700L keeps precision consistent—job after job.

FAQ Section

What makes the DNM 5700L ideal for large part machining?

The DNM 5700L’s standout feature is its 1,300 mm X-axis travel, paired with a large 1,500 mm-long table that supports up to 1,000 kg. This allows for processing of long parts, multiple small parts in a single setup, or large fixtures. The rigid cast iron base, wide roller guides, and reinforced column ensure excellent cutting performance even with heavy tools and deep cuts. It’s especially valuable in industries like aerospace, energy, and mold making where larger envelope machining is common.

Should I choose the 8,000 rpm or 15,000 rpm spindle option? 

The 8,000 rpm high-torque spindle delivers 286 Nm of torque and suits heavier cuts in steel, titanium, and other tough alloys. The 15,000 rpm high-speed spindle trades torque for speed, at 117.8 Nm, and fits better with aluminum and other materials where faster cutting speeds shorten cycle time.

How does Smart Thermal Monitoring improve accuracy?

Smart Thermal Monitoring is a sensorless algorithm that predicts and compensates for spindle heat expansion based on speed and cycle duration. This system ensures consistent machining accuracy during long jobs or when the shop environment varies. It helps reduce scrap, maintain tolerance integrity, and support unattended operations.

What is the benefit of roller-type guideways?

Compared to traditional ball guideways, roller-type linear motion guides are up to three times more rigid and twice as durable. They allow for greater stability during high-force machining and provide smoother axis movement—resulting in better surface finishes and longer component life. The DNM 5700L's guideways are also extra wide, ensuring full support of the saddle even under heavy loads.

Is this machine suitable for automation?

Absolutely. The DNM 5700L is equipped with features that support lights-out manufacturing, including:

  • Probe-readiness (Renishaw OMI-2T)

  • Adaptive feedrate and tool load monitoring

  • High-capacity tool changer options

  • Grease lubrication for low maintenance

  • Full enclosure with easy access for robotic loading
