In view of the problems and difficulties in the information system integration of the small and medium-sized super-hard cutting tools enterprises, the characteristics of the design and manufacture of the CBN turning tool were analyzed. The demand of the enterprises for the 3C integrated system of CBN turning tool was presented. The 3-layer architecture of the 3C integrated system of CBN turning tool was proposed, which included the data layer, the application layer and the user layer. The object-oriented method was adopted to design the system and the class model of the system was constructed. Based on these, the 3C integrated system of CBN turning tool for small and medium-sized enterprises was developed. The key technologies of the system were put forward. The system had been applied to the enterprise and run well.
