Influence of grain concentrations gradients on the profiling behaviour of bronze bonded diamond grinding wheels

Abstract

AbstractIn this work, diamond grinding wheels are first manufactured with two different metallic bonds. These are a ductile and a brittle bronze. Two differently graded (varied grain concentration) grinding wheels and two non-graded reference grinding wheels are manufactured in each case. The mechanical properties of these are then determined. Subsequently, a method is presented that enables the profiling of graded grinding wheels. For this purpose, the grinding wheels are profiled with SiC rolls using different profiling parameters. The profile accuracy after profiling is analysed using contour profiles in polyurethane. In addition, the dressing ratio and the process duration of profiling are measured. These parameters are used to determine the economic efficiency of the profiling process. Finally, this provides a bond-dependent profiling process that can economically and reproducibly generate a target contour on a grinding tool.
