Abstract：Mainly aimed at the precision grinding processing technology of internal thread, the research results of the existing internal thread grinding processing technology are introduced from the aspects of grinding wheel section design, grinding rod research, grinding wheel dressing and grinding technology. The advantages and disadvantages of the grinding wheel section design analysis method and the computer aided design method are analyzed. The method of reducing the vibration of the internal thread grinding rod and improving the dressing accuracy of the internal thread grinding wheel is briefly described. The research on tool setting, process parameters, ultrasonic vibration assisted grinding and grinding force in the process of internal thread processing is introduced. The development status of internal thread grinding processing technology is summarized, and the future development direction of internal thread grinding processing technology is prospected.
