Machining tools are the main equipments for metal machining and consist of mechanical parts, electrical parts and hydraulic parts, and so on. In order to reduce the probability of failure and improve the reliability of machine tools, this paper firstly performs failure analysis by statistical method. Then the failure trends for the key parts of machining center are given using power law process. In contrast with traditional method, which optimizes maintenance under repair costs, an optimization approach for maintenance is presented under the reliability constraints of machining center that used in a northeast manufacturing plant of China. The proposed analysis process could be a useful tool to assess the reliability and optimize the maintenance policy of machine tools.
