This way the cutting edge stays longer sharp!


The development team TU Graz and weba have optimized the abrasion of cutting tools. Maintenance efforts have been significantly reduced.

The Steyr`s tool manufacturer weba considerably succeeded in minimizing the abrasion of cutting tools. This success was reached through corporate research project with the Technical University of Graz by development of new tool geometry. “Through the right adjustment of the cutting edge, cutting gap and the overlap with the particular work order, we have considerably reduced the maintenance effort for the tools”, weba`s general manager Herbert Danzinger explains. Currently the tool manufacturing specialists of weba are implementing the results of the field research in the stamping and forming tools. 

During this comprehensive research project “New methods in tool manufacturing”, the specialists of weba and the Technical University of Graz realized that through the use of correct geometry, the cutting tools show clearly less abrasion and reach therefore significantly larger numbers of strokes. Thereby the resilience of the cold forming tool has been tested in a field research with the duration of many moths.  The cognition: The use of the right geometry facilitates the maintenance effort and enables saving. 

Decisive cost advantage The advantage of the new developed geometry: The cutting tools reach considerably higher durability (life expectancy). In addition to the increased availability of the tool, the maintenance intervals are extended and therefore the costs of maintenance are significantly reduced. “It enables an important saving capability in the production. And our customers will also appreciate it”, weba`s general manager Herbert Danzinger perceives in the innovation an economically added value. 

Reasonable experiments Initially, it has been tried to increase the durability by using the alternative tool materials. But the cost-advantage-effect has not been reached. In fact the prototype with the changed cutting geometry, which was built in 2007, achieved a significant optimization of the durability – even better than the theory estimated. The gained results are in the meantime being used for the enhancement of all weba-tools. Wherefore Herbert Danzinger emphasizes the significance of these experiments: “To ensure the long term success, field researches with the strategic partners and clients are imperatively essential”, weba ´s general manager explains. Further projects are already being prepared by Steyr`s tool manufacturing specialist.
