EUREKA project E! 2339 EUROENVIRON GRINDING project has developed an alternative, flexible and environmentally friendly manufacturing technology for the production of gears that can reduce production times from months to a matter of days.
It can be used for all kinds of gears and joints made from treated alloyed steel, heat-resistant nickel or titanium alloys, such as those used in turbine and jet engine blades.
The current production process for industrial gears is expensive in terms of labour, materials and time. It involves the manufacture and maintenance of gear-cutting tools, the cutting and shaping of a blank and heat and thermo-chemical treatments. In comparison, the new process “is based on precision deep grinding by a shaped grinding wheel that improves both quality and productivity of the final gears. These unique tools are made by fusing abrasive grains of alumina corundum and silicon carbide to the surface of the tool with strong ceramic bonds,” says Josef Frumar, Production Manager at Czech lead partner Carborundum Electrite a.s.
The project partners hope that this new technique of grinding exact gear shapes may become an alternative to conventional practice which relies on distinct metalworking methods to obtain precision cutting edges. In Russia alone, the annual demand for grinding wheels is over 50,000 units. “The introduction and adoption of the new gear-manufacturing technology will make it possible to increase the production rates and quality of finished gear products,” concludes Frumar.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
