Detailed explanation of the corresponding processing technology of various rollers

For different types of pin shaft rivets, the matching production and processing methods are different. For cylindrical roller bearings, the whole processing process is as follows: pin shaft fixation → mirror processing or ring belt → soft grinding of dovetail guide surface → soft grinding of double inner holes → tempering treatment → front fine grinding of turning surface → fine grinding of double inner holes → rear fine grinding of turning surface → final grinding of double inner holes → fine and final grinding of turning surface → Ultra deep processing of turning surface → cleaning and drying → final inspection of appearance and specification sequence → oiling and packaging.

However, if the tapered roller bearing is replaced, the whole process of its processing technology is: rough forming → mirror surface processing or ring belt → soft grinding of dovetail guide surface → soft grinding of double inner holes → tempering treatment → fine grinding of the turning surface → according to the m turning surface → grinding of the ball datum surface → final grinding of the turning surface → ultra deep processing of the turning surface → cleaning, dryness and impatience → final inspection of the shape and specification sequence → oiling and packaging.

The left and right roller bearings can be made into convex bus duct turning surface. If the convex measurement is less than 0.005mm, it can be carried out in the process flow of ultra deep machining turning surface immediately; if the convex measurement is more than 0.005mm, it can be polished in the process flow of one final grinding turning surface, and then the exhibition pin shaft can be disassembled.

In addition, there are also the whole process of the processing technology of asymmetric dense curved roller bearing: rough forming → mirror surface processing or ring belt → soft grinding of dovetail guide surface → soft grinding of double inner holes → quenching and tempering treatment → grinding of the price inner hole of myopia lens → grinding of the inner hole of the ball → rough, fine and final grinding of the turning surface → grinding and polishing → cleaning, dryness and impetuosity → final inspection of appearance, specification sequence → oil painting and packaging.

The whole processing process of symmetrical curved roller bearing: rough forming → mirror surface processing or ring belt → soft grinding of dovetail guide surface → soft grinding of double inner holes → quenching and tempering treatment → fine grinding of turning surface → coarse and final grinding of double inner holes → fine and final grinding of turning surface → grinding and polishing → cleaning and drying → final inspection of appearance and specification sequence → oiling and packaging. If the technological process of roller bearing final grinding turning surface can exceed the surface roughness requirements, grinding and polishing are not necessary.
