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.

烧结金属结合剂金刚石砂轮的性能取决于部件的切削性能、结合剂系统和砂轮生产中的工艺参数。结合系统的组成部分，除了硬度、导热性和砂轮密度等性能外，对切削材料融入结合基体有显著影响。这些特性的总和决定了磨削工具的磨削性能。磨料颗粒在结合基体中的化学粘附作用及其对烧结金属砂轮磨削性能的影响尚未得到详细的研究。因此，本研究项目的目的是了解磨料颗粒与结合基体之间的化学粘附特性、所产生的磨削层性能与烧结金属金刚石砂轮磨削行为之间的关系，并通过特征值来描述它们。
