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零件的切削性能、结合剂体系和砂轮生产工艺参数。除了砂轮的硬度、导热性和密度等性能外，粘结系统的组分也显著影响切削材料与粘结基体的结合。这些特性的总和决定了磨削工具的磨削行为。磨粒在结合剂基体中的化学结合及其对烧结金属砂轮磨削性能的影响，迄今为止还没有详细的研究。因此，本研究项目的目的是了解磨料颗粒和粘结基体之间的化学粘附特性，由此产生的磨削层性能和烧结金属金刚石砂轮的磨削行为之间的关系，并通过特征值来描述它们。
