Hydraulic cylinder is a kind of pressure finishing process, which uses the cold-plastic characteristics of metal at normal temperature. It uses a rolling tool to exert a certain pressure on the surface of the workpiece to make the surface metal of the workpiece plastically flow and fill in the low-pit valley of the original residue. In the meantime, the roughness of the workpiece surface is reduced.
Hydraulic cylinder adopts rolling method: broaching cylinder body - fine boring cylinder body - rolling cylinder body, the process is 3 parts, but the time comparison: grinding cylinder body 1 meter in about 1-2 days, Rolling cylinder 1 meter about 10-30 minutes.
   After the hydraulic cylinder is rolled, it has no sharp edge on the surface, and it is well-integrated with the sealing material and has a good sealing effect. This is particularly important in the hydraulic industry. Long-time movement friction will not damage the seal or seal.
   After the hydraulic cylinder is ground with a grinder or a honing machine or a rolling knife, the surface hardness of the hole is increased by about 30% , and the fatigue strength of the inner surface of the cylinder barrel is increased by 25% . If the service life of the cylinder is only considered by the cylinder, it is increased by 2 to 3 times. The boring and rolling technology is about 3 times more efficient than the grinding process. The above data shows that the rolling process of the hydraulic cylinder is efficient and can greatly improve the surface quality of the cylinder.
