First, an overview Since the founding of our country, the machine tool industry has made great progress. From scratch, from small to large, has basically established a relatively complete category of machinery manufacturing system. At present, the ownership of machine tools in our country amounts to 2.7 million units, which is more than 40 times that of the initial stage of liberation. Variety of machine tools (excluding dedicated machine tools) has reached more than 1,000 kinds of above. More than 95% of the machine tools required by all sectors of the national economy can be self-sufficient, and their export volume keeps growing.
