Abstract  In view of the difficult calibration of the spindle rotary error analyzer for ultra-precision machine tools, the system composition and measurement principle of the spindle rotary error analyzer were analyzed, and a calibration method based on indication error, linearity and repeatability was proposed. A special calibration device was built, the device uses nanometer micro-motion table to drive the displacement. Using high precision laser interferometer as measurement standard, the measuring line conforms to Abbe principle, it can be realized under normal experimental conditions. The optimal measuring ability is better than 10 nm in the displacement range of ±1 mm, and the stability of the indication value is better than 2 nm in 10 minutes. The calibration test of spindle rotation error analyzer was carried out, and the evaluation method of uncertainty was given. The calibration method and device can meet the requirements of spindle rotation error analyzer and various nanometer displacement sensors and instruments.
