Electric spark cutting is a method of forming a linear electrode. Because it simplifies the processing of molds (especially complex molds) and shortens the production cycle, it is widely used in the mold manufacturing industry. However, due to the gap between the structural design, manufacturing precision and processing technology index of China's fast-moving wire-cutting machine tools compared with similar foreign machine tools, the general wire-cutting machine tools in China cannot meet the precision machining when the machining accuracy is high.
