Application Research On Lean Production Of Forging Workshop Of Zhangjiakou Coal Mining Machinery

With rapid development of science and technology, the internationalization and globalization situation is more and more clear, the economic competition of various industries in the world is becoming fiercer and fiercer. How to create and maintain a competitive advantage in the brutal market, has become the primary problem for each enterprise's survival and development. For manufacturing enterprise, the field management, quality improvement, productivity enhancement, cost pressure will become even more important. For a long time, in some extent, the problems such as extensive management, casual process control, less strictimple mentation of rules and regulations existed in the coal mine machinery manufacturing enterprises. Adaptability of the lean production method, and the effective control method for quality, cost, and efficiency, not only contribute to the transformation and upgrading of the coal mine machinery manufacturing enterprise, but also the only route for the company getting bigger and stronger.The paper describes the origins and historical background of lean production method, the research and current status of lean production method. The paper has thoroughly studied the fine profit production method elementary theory. Based on this theory, According to the existing problems of enterprise, has formulated the company fine profit production plan of ZMM, and the problems encountered during lean production and the solutions are analyzed and compared, and presented a further improvement measures. By comparing before and after the effect of the implementation and improvement, has established the more complete company fine profit culture, through used the fine profit production tool to improve produces the scene, the Company's operating costs reduced significantly, increasing productivity.Through the application of lean production in ZMM, obtained some successful experiences, the paper research and the practice achievement has certain guiding sense to other correlation profession similar question.
