With the adjustment of the product structure of the special machining machine tool industry, the medium speed WEDM machine tool has ushered in a good opportunity for development, and has gradually become the new main force of the special machining machine tool industry. In 2001, the output of medium speed WEDM machine tools in China was only 150. By 2004, it had reached 1800 and increased to 2400 in 2005. In 2006, it is expected to have an annual output of 3500 ~ 4000, with an output value of about 2.5 billion ~ 3 billion yuan. The manufacturer of medium speed WEDM machine tools is the largest variety in the special processing machine tool industry.

The main reasons why medium speed WEDM machine tools become the new main force in the market are as follows:

Medium speed WEDM can meet the needs of equipment upgrading. In 2005, China's mold output value reached 62 billion yuan, with more than 20000 enterprises. With the continuous development of precision, complex and long-life molds, the processing equipment of many mold enterprises have been updated, and the medium speed WEDM machine tool is an essential and important equipment for mold processing. China CNC information network www.skxox.com the equipment renewal in China's aerospace, military and other fields has also promoted the rapid development of medium speed WEDM.

It has become the final processing means of precision molds. In the past, medium speed WEDM machine tools produced "metamorphic layer" on the surface, affecting the service life of molds. Now, medium speed WEDM machine tools have eliminated the "metamorphic layer", and its surface accuracy and surface roughness can meet the requirements of fine, complex and long-life molds, Like grinding, it can be used as the final processing means of precision die.
