Description

Technical Field

[0002] The bearing superfinishing process is a finishing method that uses a feed motion to achieve micro-grinding. The surface before superfinishing is generally precision turned and ground. Specifically, it refers to a finishing method that uses a fine-grained grinding tool (oil stone) to apply very little pressure to the workpiece under good lubrication and cooling conditions, and makes a fast and short reciprocating oscillation motion on the workpiece rotating at a certain speed in a direction perpendicular to the rotation direction of the workpiece. Superfinishing is the final process of bearing ring processing. It plays an important role in reducing or eliminating the circular deviation left by grinding, repairing the shape error of the groove, refining its surface roughness, improving the physical and mechanical properties of the surface, reducing the vibration and noise of the bearing, and improving the mission of the bearing.
