Super finishing is a critical process in the manufacturing of bearing rings, aimed at achieving a high-quality surface finish and improving the performance and lifespan of the bearings. This process typically involves three distinct stages: the cutting stage, the semi-cutting stage, and the finishing stage.
During the **cutting stage**, the grinding wheel comes into contact with the rough raceway surface. At this point, the initial material removal occurs as the peaks on the workpiece surface are cut away. The contact area between the wheel and the workpiece is relatively large, and the pressure per unit area is high. This stage is responsible for removing the majority of the material, shaping the surface, and preparing it for further refinement.
In the **semi-cutting stage**, the process continues, and the surface of the workpiece begins to smooth out. The contact area increases, leading to a reduction in the pressure per unit area. As the grinding wheel becomes more worn, its pores may become clogged with debris, causing it to operate in a semi-cutting condition. During this phase, the cutting marks on the surface become less pronounced, and a darker luster starts to appear, indicating progress toward a finer finish.
The **finishing stage** is the final phase of super finishing. Here, the surface of the workpiece becomes even smoother, and the contact area between the grinding wheel and the workpiece increases further. A thin layer of lubricant film forms on the surface, reducing friction and allowing for a more controlled and uniform finish. The pressure per unit area is now optimized, resulting in minimal or no visible cutting marks. The surface exhibits a consistent, bright luster, signifying that the desired level of precision and quality has been achieved.
This process not only enhances the surface integrity of the bearing ring but also improves its load-carrying capacity, reduces noise, and extends the service life of the bearing. Understanding the different stages of super finishing is essential for manufacturers to ensure optimal performance and reliability of their products.
