Description

technical field

[0001] The invention relates to a device that uses laser technology to complete the adjustment of the center of mass of the rotor so that it reaches a balanced state. Specifically, it relates to a laser precision weight removal system and method, which is mainly used to improve the balance precision of inertial navigation systems and jet engines. processing field. Background technique

[0002] With the continuous improvement of the precision and stability of the inertial gyro instrument, the accuracy and process requirements for the dynamic balance of the gyro rotor are also increased. The deweighting balance is actually completed by changing the mass distribution of the rotor. In all precision machinery and instruments with high-speed rotating parts such as gyro motors, electric motors, jet engine moving parts, etc., the functional errors (such as drift effects on gyroscopes) and disturbing swings are often caused by residues in the rotating parts. caused b...
