Development of a New Testing Method for Assessing the Wear Behaviour of Circular Cutting Discs

Abstract:

In the present work a new testing method for assessing the wear resistance of matrix materials employed in the manufacture of diamond tools is presented and discussed. The method allows assessing the wear behaviour of different metallic matrices by simulating a circular cutting action of a tool where, instead of a normal abrasive element (matrix impregnated with diamond) only the matrix material is tested. This method has originated a preliminary model of continuum abrasive contact layer between a rotating circular element made of a metal matrix and a glass material. The model allows the determination of the matrix wear rate at different applied forces. To validate the methodology used, different matrix materials (with different mechanical properties) have been analysed in relation to the experimental wear rate.
