On the issue of designing and creation of a composite grinding wheels of increased productivity for rails treatment

Abstract

The article discusses the technological aspects of the development and design of composite modified wheels used in the mechanical treatment of railway rails. It allows to increase the productivity of treatment and tool durability. An increase in the physical and mechanical features of the shard of abrasive wheels can be achieved by modifying the binder component in the composition of the ceramic charge mixture with a nanomodifier such as carbon tubes. As a result of the modification of the abrasive composition of the charge mixture, it was possible to achieve an effective performance of railway rails treatment without a significant loss in the durability of the composite grinding wheel.
