Abstract: With the advancement of high-end equipment industries such as aviation, there is a growing demand for transmission gears that offer enhanced efficiency, precision, and reliability. Grinding technology plays a crucial role in the precise formation of gears, exerting a significant influence on their surface quality and service life. Due to the intricate structure of gear teeth and the challenging task of machining hardened surface materials, issues such as excessive grinding force, elevated grinding temperature, and inadequate control over surface quality arise during gear grinding. Consequently, extensive and systematic research has been conducted both domestically and internationally on gear grinding technology, which has subsequently found practical applications in production. Based on an overview of the current research and development status of gear grinding, this paper summarizes the key research achievements of both domestic and foreign scholars in efficient gear machining, precision machining, and the mechanism behind creating grinding surface integrity. Ultimately, it concludes by summarizing and forecasting the developmental trends in efficient and precise gear grinding technology, with the aim to provide theoretical and technical guidance for high-performance gear manufacturing.

Key words: high efficiency and precision grinding, gear, grinding force, grinding temperature, surface integrity
