The Quality Improvement Research Of JNS’s CNC Machine Tool Products

With China’s rapid economic development, In the automotive, energy, marine, aviation, railways and other areas, more extensive use of CNC machine tools. In the fierce market competition, product quality and product quality management are getting more and more attention. To survive from the competition and to develop, enterprises need to enhance the quality, and put first-class quality throughout the whole process of producing. How steadily improve product quality, extend machine uptime, is a machine tool manufacturer for each core concerns.First, introduce the the JNS company product quality improvement research topics background, indicating the quality to improve the significance of the study, briefly describes the research to study ways to use market research, data analysis, the empirical analysis.Second, the literature of quality management theory, quality improvement tools are reviewed. Described the course of development of quality theory, total quality management theory and ISO9000standards and excellence in performance evaluation criteria of the relationship between cause and effect diagrams, histograms and Pareto chart used in this article, several quality improvement tools. Failure mode analysis, design improvements, improvements in quality management aspects of the quality of CNC machine tools to improve the methods and theories, which laid the theoretical basis of this paper.Again, by combing JNS in the last three years the remaining issues of customer complaints and safety notes, the use of Pareto analysis, the typical failure modes, respectively, to identify the the JNS two products exist, and were the reason, pointing out that the improved designand to tackle technical problems is the most direct way to reduce customer complaints and safety tune legacy issues; analysis of the production process, clear the assembly process is the key process of CNC machine tools production, measured in five areas from human, machine, method, analysisexist.Finally, according to the typical failure modes cause analysis, hydraulic failure, the milling head failure, submit a detailed quality improvement programs; to strengthen the quality management of the assembly process, to carry out the full quality of education, strengthen the6S management, and implementation of the Quality AwardThe five aspects of proposed improvements. Year of implementation, improve the effectiveness of the verification and analysis to improve the direction that the next step.Features and innovations of this study:the use of histograms, and cause and effect diagram Quality Improvement tools, analysis of quality defects and their causes, using the list method to analyze the factors of the specific quality problems; machine tool manufacturing industry to improve the quality management system,strengthen the process of quality control, to assess the effect of quality improvement, increasing customer satisfaction, have a practical reference.
