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.

The leaves of the lotus flower, and other natural surfaces that repel water and dirt, have been the model for many types of engineered liquid-repelling surfaces. As slippery as these surfaces are, however, tiny water droplets still stick to them. Now, Penn State researchers have developed nano/micro-textured, highly slippery surfaces able to outperform these naturally inspired coatings, particularly when the water is a vapor or tiny droplets.
Enhancing the mobility of liquid droplets on rough surfaces could improve condensation heat transfer for power-plant heat exchangers, create more efficient...
Longer, more severe, and hotter droughts and a myriad of other threats, including diseases and more extensive and severe wildfires, are threatening to transform some of the world's temperate forests, a new study published in Science has found. Without informed management, some forests could convert to shrublands or grasslands within the coming decades.
"While we have been trying to manage for resilience of 20th century conditions, we realize now that we must prepare for transformations and attempt to ease...
A University of Oklahoma astrophysicist and his Chinese collaborator have found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.
The discovery of two supermassive black holes--one larger one and a second, smaller one--are evidence of a binary black hole and suggests that supermassive...
A team of European researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. The study is published today (27 August) in Ocean Science, an open access journal of the European Geosciences Union (EGU).
Though not as frequent as in the Pacific and Indian oceans, tsunamis also occur in the Mediterranean, mainly due to earthquakes generated when the African...
In mountainous regions earthquakes often cause strong landslides, which can be exacerbated by heavy rain. However, after an initial increase, the frequency of these mass wasting events, often enormous and dangerous, declines, in fact independently of meteorological events and aftershocks.
These new findings are presented by a German-Franco-Japanese team of geoscientists in the current issue of the journal Geology, under the lead of the GFZ...
