[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. The interior of a bearing is generally composed of an inner ring, an outer ring, rolling elements, and a cage, collectively referred to as the four major parts.

[0003] Traditionally, the inner ring processing of bearings is done by clamping the bearings with a three-jaw chuck of a CNC machine tool, and then transporting the tool holder to the bearing to be processed via a slide. If the bearing is an irregular shape, the three-jaw chuck cannot fully clamp it, requiring multiple processing steps, which reduces work efficiency.
