Super precision process is not only used in the bearing industry, but also very much used in the engine, and other precision machinery and instruments have also begun to use this process.
The surface before super finishing is generally precision turning and grinding. Specifically, it refers to a finishing processing method that exerts a small pressure on the workpiece with an abrasive tool (oil stone) under good lubrication and cooling conditions, and makes a fast and short reciprocating oscillation motion on the workpiece rotating at a certain speed in the direction perpendicular to the rotation of the workpiece.
The role of bearing superfinishing
In the process of rolling bearing manufacturing, superfinishing is the final process of bearing ring processing, which can reduce or eliminate the circular deviation left by grinding processing and repair the shape error of the channel. It plays an important role in refining the surface roughness, improving the surface physical and mechanical properties, reducing the vibration and noise of the bearing, and improving the mission of the bearing.
It is embodied in four aspects
1. can effectively reduce the ripple degree.
2. improve the groove error of ball bearing raceway.
3. It can produce compressive stress on the surface of superlating.
4. The contact area of the working surface of the ring can be increased.
