The advantages of hydraulic cylinder

Date： 1970-01-01

Metal workpiece in the surface rolling process, the surface layer to strengthen the ultimate strength and yield point increases, the use of the workpiece performance, fatigue strength, wear resistance and corrosion resistance have improved significantly. After rolling, the hardness can be increased by 15 to 30%, while the wear resistance increased by 15%.

Rolling can increase the surface roughness from Ra 6.3 to Ra 2.4 to Ra 0.2. And have a higher production efficiency, and some parts can be completed in minutes or seconds.

Rolling processing can solve some of the current process is not easy to achieve the key issues. For example, the processing of large-shaped cylinder. At the same time it also applies to special small hole finishing or some special finishing materials.
