Improvement of the technological process of processing parts of coaxial radio components using thermal impulse deburring

Abstract

Purpose of the study is to improve the technological process of manufacturing small-sized parts of coaxial radio components from beryllium bronze and alloy 29 NK to reduce costs and obtain stable quality at the stage of machining. Analysis of the characteristics of parts of coaxial radio components and methods of deburring has shown that a promising method is thermal impulse deburring. For complete removal of burrs by the thermal impulse method, the selection of the tool and processing modes at the stage of blade processing was carried out in order to obtain a normalized size of burrs. The thermal impulse deburring experiment showed complete deburring while maintaining the geometry of the parts. The design of the tooling and devices for placing parts in it are proposed. The calculation of the base pressure and the required volume of the gas mixture for processing the loaded batch of parts has been developed. The calculation of the size of the batch of loading and the time of thermal impulse treatment for the production program has been developed. A technique for choosing equipment for a thermal impulse treatment section is proposed. The results of the research performed can be used to apply the operation of thermal impulse deburring in the technological process of manufacturing small-sized parts from beryllium bronze and alloy 29 NK.
