Development strategy of my country's precision and ultra-precision machining China's precision and ultra-precision machining have become increasingly mature after decades of efforts. Whether it is Swiss CNC precision machine tools, diamond tools, or precision machining processes, a complete set of precision manufacturing technology systems has been formed, which has laid the foundation for the promotion of mechanical manufacturing to a higher level. It is moving towards nanometer precision or nanometer precision, and its prospects are very encouraging. With the rapid development of science and technology and the increasingly fierce market competition? More and more manufacturing industries have begun to invest a lot of human, financial and material resources in advanced manufacturing technology and advanced manufacturing model research and implementation strategies.
