SKF bearing finishing sequence process

The first process: when the surface of the grinding stone of the SKF bearing is touched with the peak of the rough raceway surface; because the touch area is more than that of the ノ ノ 婊 氖芰 氖芰 螅 螅 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔 ㄑ沽ψ饔“ SKF bearing workpiece "anti-cutting" effect; some abrasive particles on the surface of the grinding stone fall and chipped; reveal some new sharp abrasive particles and edge. Together; SKF bearing workpiece's appearance peak is exploding Cutting; the effect of cutting and anti-cutting removes the peaks on the surface of the SKF bearing workpiece and the grinding of the enthalpy layer. This period is called the cutting period; during this period, a large amount of metal allowance is removed.
The second process: the half-cutting of the SKF bearing continues with the machining; the surface of the SKF bearing workpiece is gradually smoothed. At this time; the touch surface of the grindstone and the workpiece is added; the pressure per unit area is reduced; the cutting depth is reduced. Together; the pores of the grindstone are blocked; the grindstone is in a half-cut condition. This period is called the half-cutting period of the SKF bearing finishing; during the half-cutting, the SKF bearing workpiece has a shallower cutting mark; Luster.
The third process: during the finishing period, this is the final process of superfinishing of SKF bearings. The surface of the workpiece is gradually smoothed; the touch area of ​​the grinding stone and the external appearance of the workpiece is further increased; and; the appearance of the grinding stone and the SKF bearing workpiece Gradually blocked by smooth oil film; the pressure per unit area is very high.

During the finishing period, there is no cutting mark on the surface of the workpiece; SKF bearings appear Shine product gloss.
