If you design a automatic machine processing SKF bearing inner ring, PLC control, use the form tool. Jigs and feed mechanism for how the design it
You can take the following three stages to produce:

(1) cutting stage

Grindstones raceway surface and rough surface of the convex peaks contact, due to the smaller contact area, the pressure on the unit area is large, under certain pressure, the

grindstone first subjected to the workpiece "anti-cutting" effect, so that the grindstone surface parts abrasive loss and fragmentation, exposing new sharp abrasive edge. At the

same time, the workpiece surface convex peak by fast cutting, on the workpiece surface is removed by the cutting action of cutting and anti convex peak and grinding metamorphic

layer. This phase is called the cutting phase, the majority of the metal at this stage resection margin.angular contact ball bearings

(2) semi-cutting stage

Proceed with the processing, the workpiece surface is gradually being polished. At this time, the grindstone and the workpiece su rface contact area increases, the pressure on

the unit area decreases, depth of cut is reduced, decreased cutting ability. Meanwhile, the grindstone surface of the pores are blocked, and the grindstone in the half cutting

state. This phase is referred to as semi-cutting stage, the cutting traces of the workpiece surface in the semi-cutting stage lighter, and appears darker gloss.thrust bearing

(3) finishing stage

This is the final stage of the super finishing. With the workpiece surface is gradually flattened, the area of contact of the grindstone and the workpiece surface is further

increased, and the lubricant film gradually isolation between the grindstone and the workpiece surface, the pressure on the unit area is very small, has been insufficient to

make the grinding Dan Zirui cutting action is reduced, and finally tends to automat ically stop cutting. This phase is referred to as the finishing stage. Finishing phase of

cutting traces on the surface, there is a general gloss.cylindrical bearings
