Built for Large Part Machining Without Compromise
The DNM 5700L is engineered to meet the demands of shops requiring extra-long X-axis travel with uncompromising rigidity and precision. Featuring 1,300 mm of X travel and a spacious 1,500 × 570 mm table that supports up to 1,000 kg (2,205 lbs), this VMC delivers exceptional stability and capacity for oversized parts, fixtures, or high-density setups. The rigid Meehanite cast iron bed, wide linear roller guides, and pre-tensioned ball screws ensure that the machine maintains micron-level tolerances even under heavy loads or aggressive tool paths.
Dual Spindle Options for Torque or Speed
Whether you're roughing hard metals or finishing complex contours, the DNM 5700L has a spindle configuration to match:
8,000 RPM high-torque spindle: 286 Nm (211 ft-lbs), ideal for heavy-duty cutting and long tool life
12,000 RPM high-speed spindle: 118 Nm (87 ft-lbs), optimized for aluminum, plastics, and mold applications
Both are CAT 40 Big Plus and benefit from direct-drive architecture with oil-jacket chillers to minimize vibration and thermal growth—resulting in tighter tolerances and longer tool life.
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: 36 m/min
Z: 30 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.
Which spindle should I choose—8K or 12K?
If you prioritize torque for heavy metal removal, the 8,000 RPM spindle delivers 286 Nm of torque and is best for hard metals like steel or cast iron. The 12,000 RPM spindle provides higher speeds with less torque—ideal for precision finishing or lighter materials such as aluminum or plastics. Both spindles are CAT 40 Big Plus, direct-drive, and oil-cooled for thermal stability and high repeatability.
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
