The cutting performance of diamond tools is determined by a high quantity of single diamond crystals that are either directly brazed on a turning wheel or are mixed and sintered with metallic powder. In this regard, the lifetime of the tools can be affected by the embedment of the diamonds which directly correlates with the amount of diamonds used in the tool. Tools with only two diamond crystals with varying distances between each other were fabricated in order to simulate different diamond ratios in the tools. The distance was within the range of 1-2 mm for brazed tools and 2-5 mm for sintered tools. To analyze the wear and machining behavior of the different parameter sets, the tools were moved linearly over an inhomogeneous concrete substrate, while the clamping force was steadily increased. The measured process forces and wear of the diamonds was quantified and set into relation. This work presents in a unique way the forces and wear behavior of diamond pairs moved linearly on a concrete block.
