After landing stage metal workpiece surface rolling process, the surface to be strengthened to increase the ultimate strength and yield point, the use of performance of the workpiece, fatigue strength, wear resistance and corrosion
resistance has been significantly improved. After rolling, hydraulic cylinder hardness can be increased by 15 to 30%, while the wear resistance is increased by 15%. Rolling can increase the surface roughness Ra6.3 to Ra2.4Ra0.2, and has high production efficiency, some of the workpiece can be completed in a few minutes or a few seconds.
Rolling landing stage to solve the key problem is not easy to achieve the current process for some, the wide use of rolling process, in large, medium and small plants can use, whether from the processing quality, productivity,production costs, etc. point of view, are a relatively rolling superior processing methods. In some ways, it completely replace the grinding, grinding, honing finishing.
Delivered by an external force to the landing stage rolling tool processing methods can be divided into mechanical, Roller and spring into three categories, according to the processing properties, can be divided into light finishing,strengthening process categories.
