Diamond coatings for advanced cutting tools in honing and grinding

In high-performance machining processes, the cutting tools are an essential factor with regard to the resulting quality of the manufactured components and the efficiency of the entire production chain. For the machining of advanced materials with high hardness and brittleness, tools combining cutting and abrasive machining with high wear-resistance were developed and investigated. Focusing on honing and grinding, the development of application-adapted tools, their coating characteristics, cutting behavior and their improvements of performance are presented. The results demonstrate high wear resistance and high material removal rates in combination with significantly reduced surface roughness.
