Grinding systems of the future in practice
It becomes really interesting when someone emerges from an ocean of monotony and sameness with new ideas. In the field of grinding Mr. Gerhard Schrottner clearly succeeded in that. He has been following his vision of an inner cooled grinding wheel for quite some time. The basic idea was easy: “Fun with grinding – Grinding with fun!”
For more than 20 years Mr. Gerhard Schrottner has focused on optimizing the process of grinding and has always met with the same problem: The development of heat. Machine manufacturers have tried to solve this problem using higher flushing pressure and optimizing the supply of coolant.
In the fight against the development of heat Mr. Gerhard Schrottner is working in a totally different direction. His idea is simple: the jet of coolant is aimed at the side of the grinding wheel using the existing pipes. The force of the rotation pushes the grinding medium into a well-thought-out turbine-like labyrinth inside of the grinding wheel and exits with the right velocity through the grinding layer. Thus the grinding layer stays cool and clean.
In the field of tool grinding the coolgrind grinding wheel has been successfully used for a fairly long time. The list of success is long:
Even in the field of flat glass grinding the coolgrind system has already been successfully used and was able to significantly increase productivity: instead of the usual 60 km of flat glass per grinding wheel, 120 km of flat glass could be produced using one coolgrind grinding wheel.
The new project: Flat grinding with coolgrind
The Austrian company H-Tec Präzisionstechnik GmbH is a well appreciated partner concerning high precision. In the ongoing search for possibilities to optimize the process of grinding they came across the coolgrind system. Diverse precision parts are being flat grinded on a Favretto MR 7U – 120. All participants were astonished by the first test with a coolgrind grinding wheel with the dimensions 450 mm diameter, 50 mm wide, 6 mm layer height and grain size CBN 91.
