What is bearing superfinishing technology? Is bearing superfinishing important?

Bearing superfinishing technology is a feed movement to realize micro-grinding, and it is a finishing method. The surface before superfinishing is usually precisely turned and ground. Specifically, it refers to a finishing method that under good lubrication and cooling conditions, a fine-grained abrasive tool (whetstone) exerts a small pressure on the workpiece and makes a rapid and short-term reciprocating swing motion on the workpiece rotating at a certain speed in the direction perpendicular to the rotation direction of the dry workpiece. Ultra-precision machining is the last process of bearing ring machining, which plays an important role in reducing or eliminating the circular deviation left by grinding, repairing the groove shape error, 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.
