The Application Study Of Lean Production In A Company To Improve Projects Of1.8T Crankshaft Machining Production Line

Along with the automobile industry continues to expand the scale, the automobile industry of the key parts of the quality, performance and quantity demand has increased dramatically, but the key components of China’s auto parts enterprises are facing production line automation level is low, production layout is not reasonable, the processing cost is high, the situation of the low rate of delivery. A company is a professional manufacturer of domestic production of automotive crankshaft, its products at home and abroad, the part of the production line is also facing the same problem, which makes some customers for A company expressed concern about the ability to deliver orders, reduce its market share. In recent years, A company has been looking for solutions, through years of practice, the A found that1.8T production line in the implementation of lean production, product quality, production cost, order delivery has been greatly improved.This paper takes A company1.8T crankshaft machining production line layout as the research background, combining the theory diagram analysis method, investigation method, the analysis of A company1.8T crankshaft production line delivery rate, production cost, product quality in the production line, equipment layout, work rhythm, basic implementation of unreasonable places in order to lean production, the necessity and feasibility of the implementation of lean production and analysis of1.8T crankshaft production line of A company, design optimization of the use of the concept of lean production in A company1.8T crankshaft machining production line problems and short board, and establish the "pull","one piece flow","production" mode of production, work out the best1.8T crankshaft machining production line optimization scheme, make the products in the production line of the single flow more smoothly, reduces the cost of production line, improve product quality, and better meet customer order requirements.Preparation of standard documents, the solid foundation for A company in the crankshaft production line next step implementation of lean production.
