Super finishing order of FAG bearings can generally be divided into three steps: cutting, half cutting and finishing finishing.
The first step: FAG bearings cutting
Grinding of Raceway surface roughness of stone surfaces and protruding peaks when you touch, due to the smaller contact area, the force per unit area on a larger, under a certain pressure, grindstone first FAG bearing artifacts "anti-cutting" effect, make grindstone surface some of the abrasive loss and fragmentation, revealing some new abrasive and sharp blade edges. At the same time, FAG bearing convex peaks on the surface of the workpiece are fast cutting, through cutting and anti-cut drop FAG bearing convex peak metamorphic and grinding on the workpiece surface layer. This stage is known as cutting stage, resection at this stage most of the metallic cushion.
The second step: FAG bearing half cut
As the process continues, FAG bearing surface gradually grind. At this time, stone grinding and surface contact area increases, pressure on reducing per unit area, cutting depth reduced, cutting a reduced capacity. At the same time, surface of the grindstone pores are clogged, millstone is in a semi-cutting State. This stage is referred to as half-cut finishing stage of FAG bearings, FAG bearing cut marks on the surface of workpiece in the half cut phase lightens, and saw a dark sheen.
The third step: finishing stages
This is super finishing last steps of FAG bearings. As the workpiece surface is gradually grind, grinding stones and further increase the contact area on the surface of the workpiece, and grindstone and FAG bearing surface gradually isolated by the lubricating oil film, pressure on a unit area is very small, cutting role reduced, and finally automatically stop cutting. This phase is what we call finishing stage. Finishing stage of workpiece surface without cutting traces, FAG bearings are showing bright products luster.
