Abstract: At present, there is still a certain gap between China′s CNC machine tools and the world′s leading level, and some core technologies have not been fully mastered. In order to fully understand the research status and development trend of domestic motorized spindle technology in recent five years, from the perspective of patent analysis and based on various patent analysis platforms, the intellectual property rights between enterprises, universities and different types of patents are analyzed. The results show that domestic enterprises and colleges and universities apply for less intellectual property rights and low technological innovation in the machining center′s motorized spindle. In the follow-up research and development process, the research and development efforts should be strengthened to actively carry out the research and development of new goods, new technologies, and new processes, with an emphasis on the timeliness and significance of intellectual property.
