Abstract

The problem of early failure of domestic CNC grinding machine is studied herein. Minitab is used to analyze the machine fault data collected, and the best fitting function about it is obtained. On the basis, the early failure period about the machine is found, and the fault data in the early failure period is also analyzed by FMEA. Meanwhile, the main fault location, fault mode and fault reason in the early failure period of the machine are obtained. Some measures to eliminate the early failure, which are related to the self-made parts, purchased parts and enterprise management, are proposed. These studies lay a foundation for improving the reliability of the series machine.
