Hydraulic cylinder has what advantage?

What are the advantages of hydraulic cylinder? Metal parts in the surface rolling, the surface has been strengthened the ultimate strength and yield point increase, the use of the workpiece, anti fatigue strength, wear resistance and corrosion resistance have been significantly improved. After rolling, the hardness can be increased from 15 to 30%, while the wear resistance increased by 15%.

Rolling process can improve the surface roughness from Ra2.4 to Ra0.2 ~ Ra6.3. And there is a higher production efficiency, some parts can be completed in a few minutes or seconds.

Rolling process can solve the key problems of the present technological method is not easy to achieve. For example, the processing of a large cylinder. At the same time it is also applicable to special hole finishing or some special material finishing.

Rolling process using a wide range of large, medium and small factories are able to use. Whether the processing quality, production efficiency, production cost and so on, rolling processing is a relatively superior processing method. In some ways, it can completely replace grinding, grinding, honing and polishing.

At present, according to the external force transmission to the rolling tools of the processing method can be divided into mechanical, rolling and spring type three.

According to the processing nature, can be divided into two types of light finishing, strengthening processing.
