DNX 2100 Multi-Axis Mill-Turn Center for Heavy, Interrupted Cutting

The DNX 2100 is a DN Solutions multi-axis mill-turn center that combines turning, milling, and drilling in a single setup, built for heavy, interrupted cutting on complex parts. It runs a 5,000 RPM main spindle alongside a 12,000 RPM milling spindle, a 240-degree tilting B-axis, and full C-axis contouring, so a part that would otherwise need three or four separate machines can hold tolerance through one clamping. Ellison Technologies, the largest DN Solutions distributor in North America, supplies and supports the DNX 2100 as part of its multi-tasking mill-turn centers line for manufacturers producing aerospace, medical, and energy-sector components.

DNX 2100 Applications and Industries

Aerospace Components and Structural Parts

Aerospace shops use the DNX 2100 for structural brackets, housings, and bushings that combine turned diameters with off-axis milled features. The 240-degree B-axis and ±4.525 in. Y-axis travel reach angled holes and pockets without a second fixture, and the servo-driven tailstock holds long, thin-walled parts steady through interrupted cuts. Ellison supports aerospace manufacturers across its DN Solutions territory with the process planning and tooling these parts require.

Medical Implants and Precision Components

Medical component manufacturers run the DNX 2100 for implants and precision fittings that need turning, milling, and drilling completed before the part is unclamped, since re-fixturing risks the tolerance stack-up implant work can't absorb. The 12,000 RPM milling spindle and 0.0001-degree B-axis increment support fine contouring, and full C-axis contouring keeps cross-holes and flats on location. Ellison works with medical device manufacturers in its territory to spec the tooling and workholding these jobs call for.

Automotive and Powertrain Components

Powertrain parts such as shafts, housings, and manifolds benefit from the DNX 2100's single-setup capacity: turning the OD, drilling cross-holes, and milling flats in one clamping removes the repositioning error that shows up in high-volume automotive runs. A 1,417 ipm rapid traverse rate and a 30-station automatic tool changer with 1.7-second tool-to-tool time keep cycle time down on parts with multiple operations. Ellison supports automotive suppliers with the automation integration needed to run the DNX 2100 unattended across shifts.

Energy, Oil and Gas Components

Hydraulic fittings and other energy-sector components often mix external turning with off-center porting that would take two or three fixtures on a standard lathe. The DNX 2100's Y-axis and B-axis drill and mill those ports in the same setup as the turning operations, and the 20 bar (290 psi) coolant system clears chips from deep holes without a secondary flushing step. Ellison serves energy and oil and gas manufacturers across its territory with machines built for this kind of heavy, interrupted cutting.

Rigid Structure with Advanced Thermal Stability

Built on a heavily ribbed, one-piece cast iron bed, the DNX 2100 resists vibration and deformation even during aggressive cutting. Heavy-duty linear roller guideways provide smooth, fast movement and tight positional tolerances. Multiple thermal compensation sensors are strategically placed throughout the structure and spindle for real-time thermal drift control. The spindle chiller system ensures consistent performance during extended machining cycles, while the servo-driven tailstock maintains centerline alignment under variable load conditions.

Milling and Turning Spindles Engineered for Power

The DNX 2100 features two powerful spindles:

  • Main turning spindle: 5,000 RPM, 22 kW (30 hp), 326 Nm torque

  • Milling spindle: 12,000 RPM, 18.5 kW (25 hp), 58 Nm torque

The spindles are integral motor designs with beltless drive for maximum torque transmission, rapid acceleration, and zero backlash. The C-axis enables 360° contouring and turning, while the B-axis offers 240° of tilt for angled milling or compound hole drilling. These capabilities allow the DNX 2100 to handle multi-process parts without repositioning.

Intelligent Tooling and Y-Axis Flexibility

Equipped with a 30-tool automatic tool changer (ATC)—expandable to 60 tools—the DNX 2100 uses a CAPTO C6 interface, allowing quick tool changes with high rigidity. The ATC features random tool selection and a 1.7-second tool-to-tool time for fast cycle transitions. The orthogonal Y-axis enables true off-center machining, with the ability to mill flats, drill off-axis holes, and finish keyways without custom rotary tools. This greatly reduces setup times and fixture complexity.

Integrated Coolant, Probing, and Automation Features

To support unattended operation and increase tool life, the DNX 2100 comes with:

  • 20 bar (290 psi) high-pressure coolant system

  • Air blast for chuck cleaning

  • Automatic tool setter with 4-direction touch sensors

  • Chip conveyor and 105-gallon coolant tank

  • Grease lubrication system with cartridge-based refills

  • Safety enclosure with interlocks and signal tower

Its FANUC 0i-TF Plus control includes a 15” touch panel, 2 MB part storage, USB/Ethernet connectivity, and EZ Guide i conversational programming.

FAQ Section

What are the key benefits of the DNX 2100’s multi-axis configuration?

The DNX 2100 combines turning, milling, Y-axis, B-axis, and full contouring C-axis control in a single platform. This configuration allows for full part completion—including angled features and off-center milling—in one setup, drastically reducing changeovers, fixture complexity, and tolerance stack-up. It’s ideal for shops aiming to improve throughput on complex parts without compromising on precision.

How does the thermal compensation system improve machining accuracy?

Thermal growth can significantly affect machining accuracy during long or high-speed cycles. The DNX 2100 uses a multi-point thermal compensation system with sensors placed on the structure and milling spindle. This allows real-time adjustments that reduce dimensional drift, ensuring stable machining conditions for tight-tolerance work. Paired with oil chillers and integral spindle design, the machine maintains accuracy even under demanding conditions.

What kind of workpieces is the DNX 2100 best suited for?

The DNX 2100 is built for parts requiring multiple machining operations—turning, milling, cross-hole drilling, or angled features. Typical applications include medical implants, aerospace bushings, powertrain components, and hydraulic fittings. Its B-axis tilt and Y-axis travel make it well-suited for complex geometries and features that would otherwise require multiple setups or specialty tooling.

Is the DNX 2100 suitable for lights-out manufacturing?

Yes. With features like automatic tool setting, chip evacuation system, high-pressure coolant, and a fully enclosed work area, the DNX 2100 supports unattended machining. The machine’s robust control software includes tool monitoring, alarms, and safety interlocks that help protect the spindle, tooling, and part during automated cycles. An optional parts catcher is also available for finished part removal without operator intervention.

What is the control interface like for operators?

The DNX 2100 uses a FANUC 0i-TF Plus control with a 15” touchscreen interface, intuitive layout, and EZ Guide i conversational programming. It includes support for custom macros, multiple canned cycles, tool monitoring, program protection, and USB/Ethernet transfer. It’s engineered for both experienced G-code programmers and operators familiar with conversational control environments
