Bearing super finishing order can generally be divided into three steps: cutting, cutting half, finishing finishing.
The first step: SKF Bearings cutting
When in contact with the surface of the grindstone rough raceway surface hump, because the contact area is small, a larger force per unit area, under a certain pressure, the first to be millstone SKF bearing component "anti-cutting" effect, so abrasive grindstone surface portion and chipping off, exposing new abrasive and sharp blade edges. At the same time, SKF bearing surface of the workpiece convex peak by fast cutting, through cutting and removal of the anti-cutting effect on SKF bearing surface hump and grinding metamorphic layer. This phase is called the cutting phase, the removal of most of the metal phase margin.
The second step: SKF Bearing half cutting
As the process continues, the three Thai bearing surface gradually being polished. In this case, the contact area of the grindstone with the work surface increases, the pressure per unit area is reduced, reducing the depth of cut, cutting diminished capacity. At the same time, the surface of the pores are clogged grindstone, millstone in the half cutting state. This phase is called SKF Bearing semi-finished cutting stage, cutting in half the stage SKF bearing traces of shallow cutting surface, and appear dark sheen.
The third step: finishing stage
This is a super finishing last step bearing. As the surface of the workpiece is gradually grind, grindstone contact area with the workpiece surface is further increased, and the grindstone with the bearing surface of the workpiece is gradually Santai lubricant film separator, the pressure per unit area is small, cutting action is reduced, Finally, automatic stop cutting. We call this stage finishing stage. Finishing stage surface without cutting marks, SKF bearings showing bright luster finished.
