The test system for the axial thermal elongation and the radial vibration of high-speed spindle was studied in this paper.The analysis of high-speed spindle error and vibration error was presented, The establishment of the test platform and the procedures for the preparation of the data collection were completed, and specific compensation measures was made.The high accuracy eddy current displacement sensor, infrared temperature sensor and USB data collection card were used in the real-time non-contact measurement of the axial thermal elongation, the radial vibration of high-speed spindle and shaft end temperature. The test results show that the test system procedures structure is reasonable, run very stable and reliable and meet the real-time, dynamic testing requirements, and the study for performance Testing, the performance test,on-line monitoring and high accuracy error compensation and other research on the high-speed spindle have practical value.
