我厂从1981年4月开始严格执行对ST710转子的超速检查,暴露了跳排问题,该年废品率高达8.7%.于1982年开始攻关,经过QC小组人员的现场探索、计算,排列出因果图,并采取了对策,同年11月起一等品率稳达99.77%,消灭了废品.随后又经过二年多的观察,于1985年7月正式纳入产品图纸和工艺文件.现把调整设计和工艺参数的依据叙述如下,供同行分析指正. I plant from April 1981 began to strictly implement the ST710 rotor speeding inspection, revealed the problem of jump problems, the rate of up to 8.7% of the year. In 1982, tackling problems, after QC team members on-site exploration, calculation, arrangement of causal At the same time, after more than two years of observation, formally incorporated product drawings and process documents in July 1985. Now adjust the design And process parameters based on the following description, for peer analysis correct.
