Let high-speed cutting machine tools achieve high-speed machining

In mid-July, we visited Mr. Chen Changnian, consultant of the Machinery Industry Branch of the China Council for the Promotion of International Trade. Mr. Chen is worthy of being an expert in high-speed cutting technology. He has never stopped talking about his own business. He talked about high-speed machining at an opening and exported it into a chapter. The basic theory of high-speed cutting technology was proposed as early as the 1930s, but until the last decade or so, high-speed cutting technology began to be gradually applied, mainly because there was no support for advanced machine tool technology. In order to promote the development of high-speed cutting technology, guns and guns have been used in the past for high-speed cutting experiments, and high-speed machine tool spindles driven by diesel engines and steam turbines have also appeared, which cannot make high-speed machining an industrial practical technology. Undoubtedly, electric spindle, high-speed feed mechanism, high-speed CNC
