Optimization of technological process of repair of wheel pairs

Abstract

The article considers the question of the increase of efficiency of the machining operation the tread surface of wheel pairs of high hardness and quality. It analyzes the statistics and shows that the weakest point of the technological process of repair of wheel pairs with high hardness and quality is the machining on the profile of the tread surface. A new design of tool lather to perform turning is offering. The cutter has three inserts, two of which are designed to perform turning along the running surface. The turning effect is used separation allowance and heat generation in the cutting zone. The analysis of the stresses in cemented carbide during grinding is performed.
