Precision bearing in the process of cyclic rotation, there will be a circular rotating accuracy is poor, jiaxing bearing group co. , LTD. , first to introduce the concept of circular rotation accuracy is poor.
Bearing in the host after the installation, such as the measurement of spindle radial runout, can find its each turn of measuring value has a certain change;
Continuous measurement, can be found that after a certain number of revolution, this change will approximately duplicated.
Measure for cyclic rotation accuracy degree of the change, change needed for the approximately duplicated revolutions' quasi-periodic represent cyclic rotation accuracy, the value of the amplitude changed in quasi cycle, is the cycle rotation accuracy is poor.
Such as the proper preload on the spindle, the speed gradually rise to close to work, to implement bearing 'break-in' effect, can improve the circulation of the spindle rotation accuracy.
