我所自六十年代初开始生产表壳用不锈钢以来,已有近二十年的历史。目前我所供应的表壳用不锈钢订货量已达到每年2500吨以上,占全国表壳用钢总量的75～80％,并成为我所的主要产品之一。 1979年以后,我所的手表壳用不锈钢由Φ220轧机转到Φ300/Φ250轧机生产,产品质量有所提高,性能基本稳定。但根据用户要求降低成本提高收得率,提出厚度公差由+0.5毫米进一步缩小到+0.3毫米,全年可节约钢材约75吨。为此我车间结合创优活动,在调查的基础上对提高厚度公差精度的问题,试用全面质量管理的方法进行了分析研 I have been producing stainless steel for watch cases for almost 20 years since the early 1960s. At present, I supply stainless steel case orders have reached more than 2,500 tons per year, accounting for the total steel case of the country’s 75 to 80%, and become one of my main products. After 1979, my watch case with stainless steel Φ220 mill to Φ300 / Φ250 mill production, product quality has improved, the basic performance and stability. However, according to the request of the user to reduce the cost and increase the yield, the thickness tolerance is further reduced from +0.5 mm to +0.3 mm, saving about 75 tons of steel throughout the year. To this end, my workshop combined with excellent activities, on the basis of the survey to improve the accuracy of the thickness tolerance problems, try the total quality management methods were analyzed
