An efficient and environmentally friendly way of manufacturing gears

21.01.2004


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.



Carborundum Electrite a.s. may have 100 years of experience in the production of grinding wheels, but an unsuccessful privatisation trial during the last decade left it without an R&D department. “Our Russian partner carried out the fundamental research while we provided trial testing and implementation,” explains Frumar.

Prof. Viktor Starkov, Director of the Research Centre at the Moscow State Technical University, ’Stankin’, describes how it carried out most of the research work. “We developed various formulae for new high-porosity tools and conducted industrial tests in 14 Russian factories, together with theoretical analysis and experimental research, which created a basis for the development of this new technology of gear production by profile depth grinding.”

Frumar describes the benefits of being in a EUREKA project: “The EUREKA scheme provided the perfect chance for international co-operation on projects which will produce products that are the first on the market and ahead of our competitors.”

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Autonomous 3D scanner supports individual manufacturing processes

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).

Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
