Preparation Process of Sliding Bearing of Precision Motorized Spindle

[摘要] Aiming to realizing the high efficiency and high precision of manufacture, the requirements of the bearing manufacturing process were pointed out for the application of high-precision motorized spindles. A standardized bearing manufacturing process was proposed. Furthermore, the manufacturing process flow was verified with three steps of manufacture of sliding bearing, including 3D modelling, simulation processing, bearing processing. Stiffness and vibration of the sliding bearing manufactured were tested on motorized spindle bearing testbed. The result showed that the sliding bearing manufactured has the characteristics of high rigidity and low vibration, and meet the requirements of precision motorized spindle. Process design method in this paper provides an important reference for high-precision bearing manufacturing.
