The summary：CNC machine tools is required for this generated a new type of automatic machine tools. CNC machine tool set of microelectronics technology, computer technology, automatic control technology and servo drive technology, precision machinery technology in one, is highly typical of Mechatronics products. As a result of CNC machine tools is an expensive precision equipment. Therefore, NC machine tool fault diagnosis and repair of NC machine tool in use process is the important component, is also the current constraints of CNC machine tools play a role in one of the factors, so the study of NC machine tool fault diagnosis and repair technology and method has important significance.
