Dynamic and static optimization design analysis of spindle characteristics in CNC machining

Due to the rapid development of science and technology, continuous innovation in the construction machinery industry, high-speed CNC machining technology welcomes the best period of reform and development, promotes the high-speed manufacturing of CNC machining technology, and the popularization of the machining industry should improve the efficiency of CNC machining center design. Among the key components of CNC machining centers, electric spindles directly affect machining efficiency and the economic benefits of manufacturing companies. Therefore, the technology of structural optimization, Excellent performance has been achieved in high-speed CNC machining.
​
At present, the high-speed electric spindle CNC machining center is used as the main mechanism for studying and explaining the electric spindle system. Based on understanding the basic structure of the electric spindle, theoretical analysis has been conducted on the electric spindle, three-dimensional software modeling and finite element simulation have been conducted, and simulation data and finite element analysis have been used to solve the results. This has improved the optimization design of the electric spindle and improved the relevant performance of the electric spindle, Firstly, based on the relevant dimensions of the electric spindle CNC machining center with parameters, a structural analysis system is conducted for the electric spindle and the corresponding lubrication and cooling system supporting the bearings.

On this basis, software finite element analysis is used to couple the electric spindle, and the maximum displacement static analysis and map cloud of the corresponding displacement calculation are carried out on the CNC machining center at the same time. Then, under two different constraint conditions, the unrestricted free state and modal analysis of the electric spindle system are obtained, and the natural frequency and corresponding vibration mode of the electric spindle are obtained under three different states.

For the modal analysis of the electric spindle and the analysis of the harmonic response of the front end of the electric spindle, it is performed to better understand the dynamic performance of the electric spindle. Therefore, for the design of subsequent optimization methods, software optimization of the CNC machining center optimization analysis is carried out. The data results show that the model system parameters of the electric spindle are first set, and the electric spindle is adjusted and optimized to correspond to the installation position of the bearings to meet higher production requirements.
