一、前言 为了更好地贯彻科学技术为经济建设服务,促进四化建设。本小组接受了上海钢铁研究所的委托,对表壳用不锈钢(oCr18Ni9或18-8)及近年来该所研制成功的二种表壳用易切削不锈钢(18-8S-1及18-8S-2)进行了系统的切削加工性能对比试验和分析。 手表是广大群众经常使用的轻工业产品,随着人民生活水平的不断提高,不但对手表的数量与机芯的质量,而且对表壳的款式及造型等方面也都有着更进一步的要求。
I. Preface In order to better implement science and technology and serve the economic construction and promote the four modernizations. The team accepted the commission of the Shanghai Institute of Iron and Steel, the case with stainless steel (oCr18Ni9 or 18-8) and in recent years the successful development of the two cases with free cutting stainless steel (18-8S-1 and 18-8S- 2) Conducted a comparative test and analysis of the system’s cutting performance. Watches are the light industrial products frequently used by the broad masses of the people. With the continuous improvement of people’s living standards, not only the quantity of watches and the quality of the movement but also the style and shape of the case also have further requirements.
