Abstract

Some issues related to the possibility of increasing the efficiency of shaping blade tools from polycrystalline superhard materials by diamond grinding are considered. It has been established that one of the ways to increase the efficiency of using diamond micropowder grains in circles is to apply thick metal coatings on them. The use of embossed metal coatings on diamond grains can significantly extend their cutting resource. This is explained on the one hand by a stronger adhesion of the coating material to the diamond surface compared to the components of the binder, and on the other hand, a significant increase in the contact surface of the coated grain with the binder of the circle. It was established that the strength of metal and ceramic ligaments should be consistent with the strength of diamond grains sintered with it, and the concentration and graininess of the latter have a significant impact on the integrity of the grains in the sintered layer.
