In the past, the surface of the medium-speed WEDM machine tool will have a "metamorphosis layer", which will affect the die life. Now the medium-speed WEDM machine tool has gone through the "metamorphosis layer", and its appearance accuracy and roughness can meet the needs of fine, messy and long-life molds. It can be used as a means of fine mold processing as well as grinding. According to China Machine Tool Network, because of a series of advantages of medium-speed WEDM machine tools, the development trend of "cutting instead of grinding" is increasingly obvious.

The medium speed WEDM machine can meet the needs of equipment upgrading. In 2014, China's mold production reached 120 billion yuan, with more than 100000 companies. With the continuous development of fine, disordered and long-life molds, many mold companies' processing equipment is numerous and updated, and the medium speed WEDM machine tool is an essential and important equipment for mold processing. The renewal of equipment in China's aerospace, military and other fields has also promoted the rapid development of medium-speed WEDM machines.
