这份材料是根据我国赴日机床参观组金振华同志提供的有关日本组合机床与组合机床自动线方面的资料选编的,可供研究国外组合机床及组合机床自动线技术发展动向时参考。很多原始材料和数据是日方提供和口头介绍的,由于资产阶级本性所决定,其中会有不少夸大和故弄玄虚的地方,请读者注意。 This material is based on the data provided by Comrade Kim Chun-hua, a visiting group of Japan’s go-Japan machine tools, on the automatic line of Japanese combination machine tools and composite machine tools, which can be used for reference when studying the development trend of automatic line technology of foreign combination machine tools and composite machine tools. Many of the original materials and data were provided by the Japanese side and introduced orally. Due to the nature of the bourgeoisie, there will be many places where the exaggeration and the mystery will be exaggerated. Please draw readers’ attention.
