Abstract

In the context of rapid industrial advancement, there is an increasing demand for high performance and precision, particularly in the widespread application of hole structures. Tungsten, a material with an extremely high melting point and excellent physical properties, poses significant challenges to machining techniques. This paper introduces an electrochemical discharge machining (ECDM) method, combining electric spark perforation and electrolysis in a saline solution with specific conductivity, effectively enhancing the efficiency of micro-hole machining in tungsten. The rapid formation of discharge channels, facilitated by the generation of gas, improves both erosion efficiency and discharge efficiency. Compared to traditional electric discharge machining (EDM), ECDM not only maintains high machining efficiency but also significantly improves the quality of machining by removing recast layers and micro-cracks through electrolytic action. This study demonstrates the advantages of ECDM in high-quality hole machining through comparative experiments, analyzes the machining outcomes under different electrical parameters, and achieves process optimization for tungsten hole machining, providing effective technological support for enhancing the reliability of tungsten in high-performance applications.
