The properties of sintered metallic bonded diamond grinding wheels are dependent on the cutting properties of the components, on the bonding system and the process parameters in the production of the grinding wheels. The components of the bonding system, in addition to the properties, such as the hardness, the thermal conductivity and the density of the grinding wheel, significantly influence the integration of the cutting material into the bonding matrix. The totality of these properties determines the grinding behavior of the grinding tool. The chemical adhesion of the abrasive grains in the bonding matrix and their influence on the grinding behavior of sintered metal grinding wheels has not been investigated in detail so far. The aim of this research project is therefore to understand the relationships between the characterization of the chemical adhesion between the abrasive grain and the bonding matrix, the resulting grinding layer properties and the grinding behavior of sintered metal diamond grinding wheels and to describe them by means of characteristic values.

烧结金属键合的钻石砂轮的性质取决于组件的切割特性，粘结系统和生产磨轮的过程参数。除了性质之外，键合系统的组件（例如硬度，导热率和磨轮的密度）显着影响切割材料在粘合基质中的整合。这些属性的总体决定了研磨工具的研磨行为。到目前为止，尚未详细研究键合基质中磨料晶粒中的化学粘附及其对烧结金属研磨轮的磨削行为的影响。因此，该研究项目的目的是了解磨料颗粒与粘结矩阵之间化学粘附的表征之间的关系，由此产生的研磨层的性能与烧结金属钻石磨石车轮的研磨行为，并通过特征值的方式来描述它们。
