Effect of the Jet Pressure of Reinforced Grinding on the Surface of Bearing Rings

Abstract

Under the condition that other process parameters unchanged, 5 groups of bearing rings were processed under different jet pressure of reinforced grinding, and EDM was used for wire cutting after finishing the process. The cut patterns were observed under scanning electron microscope. It is found that the grinding bearing rings form a micro oil reservoir with self-lubrication, which can help to improve its wear resistance and fatigue life. The number of toil bags are increased with the increase of jet pressure.
