Optimization and Verification of Sliding Saddle Structure in Machining Centers

As one of the key components of CNC machining centers, the structural performance of the saddle plays an important role in the machining accuracy of CNC machine tools. Taking the high-precision machining center of a certain factory as the research object, a finite element model of the sliding saddle is established. The ANSYS software is used to perform static analysis on the sliding saddle under extreme working conditions, analyze the deformation of the sliding saddle under this working condition, identify the weak links of the sliding saddle, and optimize its structure and size. Static stiffness verification and modal analysis verification are carried out. The results show that the optimized machining center saddle has high static stiffness and does not exhibit resonance under normal working conditions.
