At the Chicago Technology Days DMG MORI presented the NLX 2500|700 2. Generation, a successor model of the best-selling turning center, implementing deep-reaching optimizations in machine structure, control and various functionalities. The innovation leader has considered the requirements of today's markets and embedded the new model in the Machining Transformation (MX) concept. Process Integration, Automation, Digital Transformation (DX), and Green Transformation (GX) are the key pillars of this concept with which DMG MORI is shaping the future of manufacturing. The NLX 2500|700 2. Generation provides users with various needs with maximum flexibility and running autonomy in universal turning. The core characteristics of the powerful NLX series – its stability and the associated precision – have been enhanced even further. The aim is to reduce throughput times and increase machining quality. With these measures and the adaption of high torque turnMASTER spindles on the left and right, the NLX 2500|700 2. Generation will continue to set standards in the productive heavy-duty machining of demanding workpieces.
Precision machining for a wide range of workpieces
Enhanced and fine-tuned box guideways, stable roller guides with a width of 55mm and double anchored ball screws ensure high rigidity in the machine’s guide and drive geometry. The sophisticated temperature stabilization and compensation minimizes thermal displacements coming from machine operation and environment. Among other measures, this is guaranteed by internally cooled ball screws, machine bed and spindle temperature control. In addition, direct measuring system smartSCALE provide longtime stability in production and prolonged drive accuracy. The turret is available as a BMT60, BMT40 or VDI40 with ten to 20 tool positions. The driven tools reach speeds of up to 12,000rpm or torques up to 100Nm depending on the machining needs. Designed for extreme heavy-duty machining, the left 10" turnMASTER spindle of the NLX 2500|700 2. Generation offers a torque of up to 828 Nm, optionally even up to 1273 Nm with the 12" version. The right spindle is available in 6", 8", and 10" design with a torque of up to 577 Nm at the top end.
With a maximum turning diameter of ø 366mm and a turning length of up to 705mm, the NLX 2500|700 2. Generation offers capacity for a very wide range of workpieces. The maximum bar capacity for operation with bar feeders is increased to ø 105mm on both spindles compared to ø 80 mm on the previous generation. The travel distances are 260mm in the X-axis and 795mm in the Z-axis. A travel of 120mm (± 60mm) in the Y-axis allows off-center milling, drilling and further operation with driven tools for more flexibility. Measurements can be carried out during machining at various positions, allowing users a high degree of process integration.
Integrated processes through exclusive DMG MORI technology cycles
The stealth design makes the NLX 2500|700 2. Generation more durable and easier to maintain, while the user-friendly ERGOline operating panel is available with MAPPSX (FAMUC 31iB Plus) or SIEMENS SINUMERIK ONE. Numerous exclusive technology cycles facilitate workshop-oriented programming in both cases. For example, complex processes such as gear hobbing can be integrated, enabling the NLX 2500|700 2. Generation to fulfill a key requirement in Machining Transformation (MX).
Automated universal turning for maximum productivity
Just like the integration of multiple processes in one workspace, the automation of production also plays a major role in the context of Machining Transformation (MX). The range of flexible automation solutions for the NLX 2500|700 2. Generation includes the classic gantry loader and various robot-based products, including the Robo2Go and the IMTR or the MATRIS light and the WH-AMR 10 as autonomous mobile robots for handling workpieces. Integrated solutions for automatic unloading of workpieces are also available to match working with bar feeders. These automation solutions are operated directly via the SIEMENS or MAPPS control system. Extended machining autonomy on the NLX 2500|700 2. Generation allows continuous production even in unmanned night and weekend shifts. Machine utilization can be maximized in order to keep production lean. All of this without making compromise in sustainability and reducing use of resources like lubrication oil, coolant, compressed air and electricity.
Efficient use of energy and resources
Compared to the first NLX generation, the NLX 2500|700 2. Generation is more economical and efficient in all respects. Power consumption has been reduced by 16%, air and oil by 12% and 50% respectively. With an extensive coolant and chip management in place, the coolant in use gains longevity, reducing total consumption, meaning that the machine also supports the Green Transformation (GX) in the long term.
