China's strategy of precision and ultra precision machining of China's development of precision and ultra precision machining after decades of efforts, has become more and more mature. Whether the precision machine tools, diamond tools, or precision machining technology has formed a complete system of precision manufacturing technology, to promote manufacturing to a higher level of development laid a good foundation. Is moving to the nanometer level precision or nm precision, and its prospects are very encouraging. With the rapid development of science and technology and increasingly fierce competition in the market? More and more manufacturing companies will start a large amount of manpower, financial and material resources to study and implement the strategy of advanced manufacturing technology and advanced manufacturing mode.
