The invention provides a high-frequency micro-vibration isolation device of a spacecraft control moment gyroscope. The high-frequency micro-vibration isolation device is of a central symmetry structure and comprises an installation plate (1), a bottom plate (3) and vibration isolation units arranged between the installation plate (1) and the bottom plate (3). Each vibration isolation unit comprises a radial damping unit (4), an axial damping unit (5) and an elastic supporting unit (6). According to the novel micro-vibration isolation device, vibration isolation performance is good at CMG work rotation speed, six-degree-of-freedom micro vibration transferred to a star body can be effectively reduced, and posture stability and pointing accuracy of the star body can be improved.
