Improving the structure of an abrasive tool without binder

The size distribution of the abrasive grains after shock-wave pressing corresponds to an asymmetric β distribution, as noted in [2]. The nonuniformity in the size distribution of the pores over the tool volume is 20%. This has a considerable influence on tool performance, since sections with pores of different size appear at its working surface, which results in spoiling of these sections and loss in cutting power of the tool. Thus, cutting and noncutting sections appear randomly at the tool’s working surface. This impairs the surface quality of the final part.
