Efficient precision grinding of machine components

10.06.2013
Reducing energy and lubricants in the automotive industry

In mechanical engineering, maximum precision is required for the final machining. Therefore in order to ensure the quality of the workpieces, it is important that as little frictional heat as possible is created and the unavoidable rash is removed.

The latest BINE-Projektinfo brochure “Energy efficient finishing in mechanical engineering” (03/2013) presents a new grinding process for the automotive industry that requires minimum amounts of lubricants and coolants. In comparison with the previously standard flood cooling, the new process halves the energy consumption.

The new process, called minimum quantity lubrication, has been tested for the first time on an industrial scale on the camshaft production line at Volkswagen AG’s factory in Salzgitter. The researchers optimised the grinding machine, abrasive body and the lubricant feed. The aim was to create no more frictional heat than can be removed via the tool and chips without damage. For this purpose the manufacturing process for the grinding media was changed, whereby it was furnished with a lasered, microstructured surface. The lubricant is now sprayed on via a dual-channel nozzle system. This enables the compressed air and lubricant to be optimally mixed.

The manufacture of camshafts provided a natural choice as a pilot application because the induction-hardened chromium steels, workpiece geometry and the required precision are very demanding. If this project runs successfully, the new process can also be transferred to other production processes.

The previous results have been very promising. With the two million camshafts produced at Salzgitter every year, the electricity consumption during their production can be reduced by at least 2.4 million kWh. This contrasts with the minimal additional investment of four cents per camshaft.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
