Abstract
With the strongly support from the country for the manufacturing industry, valve industry will be gradually appreciated. This paper mainly introduces some technical parameters requirements of ball valve. During the analysis of traditional valve machining process, proposing a new processing mode about ball valve grinding: Electrical Discharge Machining (EDM). By comparing three different electrode materials at different stages in processing results, selecting the most reasonable electrode materials correspond to the process stages to increase the accuracy and efficiency of machining core of ball valve.
