In this paper

the research progress and development direction of the high-speed motorized spindle thermal error compensation technology at home and abroad in recent years has been described

focusing on the analysis of the motorized spindle data detection technology

the temperature measurement point optimization technology

the thermal error modeling technology

the thermal error compensation method

and other aspects. Finally

to promote the development of high-speed motorized spindle thermal error pre-compensation technology

its future research direction has been prospected. The analysis and the outlook of the current situation of several key stages of the high-speed motorized spindle thermal error compensation technology will play an important role in guiding the progress of the thermal error control technology in the field of CNC machining.
