Precision forging machine is widely used in the processing for special raw materials in the fields of national defense and aerospace and has become a “great power” gradually. Therefore, the latest research results of forging box of main engine for precision forging machine were introduced. Then, the forging box of main engine was distinguished based on the different movement modes of hammer head, and the design and optimization process of external box and internal hammer head were summarized. At the same time, the research on the collet structure of manipulator was reviewed. Furthermore, combined with the working principle of precision forging machine, the control difficulties of hammer head synchronous movement, collet rotation and axial feeding of manipulator during the forging process were discussed, and the solutions were proposed. In addition, the research status of integral control system of precision forging machine was summarized, and the design of special CNC system was put forward on this basis. The influences of process parameters for precision forging machine on forging quality were investigated, and a method combining simulation optimization and real-time monitoring was proposed to improve forging efficiency and accuracy. Finally, the overall domestic research and development ideas of precision forging machine equipment were summarized, and the development direction of precision forging machine was prospected.
