The numerical control technology and numerically-controlled machine tool's widespread application, for machine-building industry's industrial structure, the product type and the scale as well as the production method have brought the revolutionary change. The numerically-controlled machine tool is the modern processing workshop most important equipment. Along with the modern technique of manufacture's development, the enterprise selects the numerical control equipment already is ultimately. I am at the practice company main product is the communication foundation equipment and the remote sensing product. The axis, the housing and the lap and so on manufacture is mainly with the numerical control lathe, the machining center and the numerical control milling machine, the drilling machine and so on completes. But will meet the electric control system unavoidably in the numerical control lathe in the work process the breakdown, for this reason, this paper will introduce the numerical control lathe's electric control system common breakdown diagnosis.
