Abstract: Advances in construction machinery technology are driving an increasing demand for the high-performance bearings. Due to the existence of problems such as clamping deformation, cutting deformation and thermal deformation during bearing machining, the accuracy of finished bearings is seriously restricted, so the deformation control technology during bearing machining has become the focus of research by various manufacturers and institutions. This paper aims to present a comprehensive overview of the current research progress in bearing machining deformation control, analyzes the causes of bearing machining deformation (including cutting force, cutting temperature, cutting tools and other factors). The paper provides a detailed discussion of prevalent methods for controlling bearing machining deformation, such as changing the machining method, changing the structure of the chuck and machining parameters control, etc. Finally, this paper analyzes the advantages and disadvantages of the various bearing processing deformation control methods currently employed. The future trends in research on bearing processing deformation control are also discussed. Given that researching bearing machining deformation control is an important direction in the machining field, this paper will have a positive impact on improving the quality and efficiency of bearing machining.
