[0002] Medium-speed wire EDM machine tools belong to the category of reciprocating high-speed wire EDM machine tools. They realize multiple cutting functions on high-speed reciprocating wire EDM wire cutting machines. They are commonly known as "medium-speed wire cutting". The so-called "medium-speed wire cutting" does not mean that the wire speed is between high speed and low speed, but a compound wire cutting machine tool. That is, the wire cutting principle is to use high-speed wire cutting for rough machining and low-speed wire cutting for fine machining. In this way, the operation is relatively stable and the jitter is small. Multiple cutting can reduce the error caused by material deformation and molybdenum wire loss, so that the processing quality is relatively improved. The processing quality can be between high-speed wire cutting machine and low-speed wire cutting machine.
