Abstract
This research is devoted to the in-depth analysis and optimization of the mechanical properties of precision CNC machine tools. We provide a comprehensive overview of precision CNC machine tools, including their definition, classification and key technologies, laying a solid foundation for subsequent performance analysis and optimization. Through the detailed analysis of the bed structure, the spindle system and the tool and workpiece holding device of the precision CNC machine tool, we deeply understand the mechanical structure characteristics and design requirements of the machine tool. The key problems in mechanical properties of precision CNC machine tools, such as thermal deformation, vibration and noise, insufficient stiffness and servo system response lag, are emphatically discussed. These problems not only affect the machining accuracy and stability of the machine tool, but also restrict the application of the machine tool in the field of high-end manufacturing. In order to solve the above problems, a series of optimization strategies for mechanical properties of precision CNC machine tools are proposed in this study. In terms of thermal balance design and temperature control technology, we have studied effective thermal isolation and heat dissipation measures to reduce thermal deformation of machine tools. In terms of isolation system and dynamic balance optimization, we introduce advanced vibration control technology to effectively reduce the vibration and noise of the machine.
