The miniaturization of machine tools has become one of the current research hotspots in the field of machining. According to different processing objects and application conditions

a variety of micro and small machine tools have been developed

which can realize economical processing and save space

energy and resources. It can also be used in teaching and education to improve student participation. Combining the processing advantages of wire EDM

a desktop type reciprocating slow wire EDM wire cutting machine is developed

the basic structure of the machine tool is designed

and the PID constant tension wire transport system and the open loop motion system are constructed. Different types of machining comparison tests have been carried out to prove that the machine tool has good overall accuracy and can complete high-quality machining tasks with different requirements.
