Abstract With the rapid development of modern manufacturing, the requirements for milling machine products are becoming higher and higher, leading to higher requirements for the working accuracy of milling machines. It is necessary to use the finite element method for static analysis of key components. This article uses 3D software to establish a geometric model of the milling machine saddle and establishes a finite element model. Finite element analysis is performed on the stiffness and strength of the sliding saddle in the middle of the crossbeam and the spindle sleeve at the lowest end of the sliding saddle under the load condition. Through analysis, it is known that the milling machine slide saddle is located in the middle of the crossbeam, and the spindle sleeve is located at the lowest end of the sliding saddle, which is the worst working condition. According to the strength theory, it is verified that its strength meets the requirements. This static analysis can provide reliable data for the design optimization of the milling machine saddle.
