1973年,我厂用普通车床改装成CK 6163C数控车床,用于加工φ400 mm车床的主轴,15年来已累积加工了78000件。 我厂生产的车床床头箱2088法兰盘,若在日本40 N车削中心加工,用日方提供的程序实际加工时间 15 min,而用我厂新开发的S1-291普通型数控车床仅用 6 min。加工部位完全一样 In 1973, our factory converted into a CK 6163C CNC lathe with an ordinary lathe and used for machining the spindle of a φ400 mm lathe. Over the past 15 years, 78,000 pieces have been accumulated and processed. I produced 2088 flange lathe headstock machine, if the machining center in Japan 40 N, with the Japanese side provided the actual processing time of 15 min, but with our newly developed S1-291 ordinary CNC lathe only 6 min. Processing parts exactly the same
