In the past, medium speed wire EDM could meet the needs of equipment upgrading. In 2010, China's mold output value has reached 120 billion yuan, and there are more than 100000 enterprises. With the continuous development of precision, complex, long life mold, many mold enterprises have updated the processing equipment, and medium speed WEDM machine tool is an essential important equipment for mold processing. China's aerospace, military and other fields of equipment updates, also promote the rapid development of medium speed WEDM.
