Abstract Grinding is a significant approach to realize the machining of high performance and precision parts. However, the wheel loading phenomenon seriously restricts the application of grinding technology in the precision manufacturing of ductility aeronautical alloys components. The recent advances in this field are reviewed in this paper. Firstly, the mechanism of adhesive wear and wheel loading are comprehensively elaborated, and the effective factors of wheel loading are identified. The adverse effects that wheel loading brings on the grinding force and grinding temperature as well as the work piece surface quality after grinding are analyzed. Subsequently, the research actuality of the wheel loading modelling is presented. Meanwhile the limitations of application of these models are analyzed. Then, the recent advances of the suppression technology of wheel loading are described, which includes research on the selection of grinding parameters, the improvement of cooling and lubricating conditions in grinding zone, the structure design of grinding wheel, the in– process cleaning and dressing technology and electrochemial grinding. Finally, the research direction of wheel loading issue in the future is prospected from the viewpoint of engineering application.
