50% reduction in the energy consumption possible
Modern machine tools offer a diverse range of possibilities: they drill, mill, saw, turn and grind fully automatically. These production steps, which comprise the different metal-cutting processes, often only make up around 20% of the machine’s energy consumption.

Most of the energy is consumed by peripheral systems such as the hydraulics, cooling and lubrication. The BINE-Projektinfo brochure “Making machine tools work more efficiently” (03/2014) presents a research project that analysed the energy consumption of the individual machine components and developed optimisation concepts.
Energy savings of up to 50% are possible. In some cases the additional measures pay for themselves after just a few months.
The most energy intensive components in machine tools are the cooling lubricant systems, machine cooling and hydraulics. These formed the focus of the research work. For the investigations, a 4-axis machining centre was used similar to those deployed in the automotive industry, and which was re-equipped for research purposes.
This has resulted in a diverse range of optimisation concepts for individual components. As part of the project, a software tool has also been developed that compares various configurations for machine tools and supplies analyses of the energy consumption and costs at an early stage.
The research project is being led by the Institute for Production Management, Technology and Machine Tools (PTW) at TU Darmstadt. Partner companies are also involved from the mechanical engineering, component manufacturing and automotive production fields.

About BINE Information Service
Energy research for practical applications
The BINE Information Service reports on energy research topics, such as new materials, systems and components, as well as innovative concepts and methods. The knowledge gained is incorporated into the implementation of new technologies in practice, because first-rate information provides a basis for pioneering decisions, whether in the planning of energy-optimised buildings, increasing the efficiency of industrial processes, or integrating renewable energy sources into existing systems.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
