The main advantage of horizontal milling and drilling is that chips can fall freely downwards and be easily removed. With travel paths of 1,400 x 1,200 x 1,350 mm, the NHX 8000 4th generation offers enough space to process large engine blocks securely. This is particularly beneficial for aluminum, gray cast iron, and vermicular graphite cast components, as the horizontal spindle orientation minimizes chip accumulation in the deep pockets and holes of complex workpieces. The secure processing also increases tool life, contributing to cost-effectiveness along with multi-sided machining. It reduces setup times and thus also non-productive times, and facilitates the machining of components with low positional and reference tolerances. For example, engine blocks and cylinder heads have numerous holes, sealing surfaces, and threads that require high precision form and positional tolerances across different sides. The design and the resulting structural advantages give horizontal machining centers a strategic advantage over vertical machine concepts.
Machine rigidity during roughing or finishing
Horizontal machining centers like the NHX 8000 4th generation impress with their enormous machine rigidity, allowing them to handle high machining volumes. This is particularly advantageous for machining large cast parts with numerous flat surfaces and deep holes. At the same time, the stable construction ensures precise manufacturing with high repeat accuracy. This allows even the most demanding holes and fits to be realized with consistent quality over large series.
The spindle range of the NHX 8000 4th generation includes both spindles with 16,000 rpm and a powerMASTER spindle with a torque of 1,413 Nm, enabling the machine to showcase its strengths in all application areas.
Automation solutions on offer
Beyond its structural advantages, the NHX 8000 4th generation proves to be an optimal basis for automated production. In the machining of engine blocks, round pallet storage or linear pallet pools (LPP) are suitable. The latter can link up to eight machines, have space for a maximum of 99 pallets, and feature up to five setup stations that can be operated both manually and optionally automated. Additional process steps can also be integrated into an LPP, such as a laser station that marks the components for further tracking. Fully automatic manufacturing solutions enable users to prepare new orders in parallel with main time and simultaneously maximize spindle running times. Autonomous transport systems like DMG MORI's AMR series create additional space as needed. They automatically supply the machines with new tools and handle the removal of chips.
A well-thought-out automation approach also preserves the flexibility of production. The industry has been undergoing a shift away from conventional drives towards hybrid and electric vehicle technologies for several years. In this transformation process, it is essential to design production systems that can accommodate technological changes without sacrificing efficiency. Horizontal machining centers offer a decisive advantage here: they combine series productivity with structural adaptability. New component geometries, modified clamping concepts, or adjusted batch sizes can be integrated into existing system architectures without the need to completely rebuild production lines.
Partners for a sustainable transformation
DMG MORI aims to support holistic solution provision. The machine tool manufacturer combines the horizontal machining center with optimal automation and numerous digital solutions that enable a fully connected production with intelligent monitoring and transparent documentation. This philosophy supports a sustainable transformation and creates future-proof structures for competitive manufacturing in the mobility sector.
