ABSTRACT

In this paper, according to the characteristics of high speed and high precision CNC lathe, a detailed analysis is made after consulting the relevant literature and a large amount of data. The hydraulic system is finally designed and a more suitable hydraulic system is designed. After consulting a large amount of data, the development of high speed and high precision CNC lathes and the combination of hydraulic technology at home and abroad are introduced. At the same time, the application field and development status of high speed and high precision CNC lathe in China are expounded, and the development trend in the future is discussed.
Firstly, the structure of the lathe is analyzed, and the main working parameters of the main components are selected through calculation and literature review. Then, according to the functional requirements of the machine tool, the hydraulic system is analyzed, and the design scheme of the hydraulic system is finally determined. The main hydraulic system was selected and optimized, the hydraulic system was drawn by AutoCAD, the hydraulic circuit scheme was determined, the hydraulic components were selected and some parts of the system were designed. Finally, the design is checked to ensure that the design can achieve the desired results in practical work.
