Hydraulic cylinder processing: Cylinder is the most important parts of construction machinery hydraulic cylinder manufacturers, traditional processing methods are: Broaching cylinder - fine boring cylinder - grinding cylinder. Using rolling method is: Broaching cylinder - fine boring cylinder - rolling hydraulic cylinder specifications, process is a three part, but the contrast in time: grinding cylinder about 1 m in 1-2 days , rolling cylinder about 1 m in 10-30 minutes. Hydraulic cylinders Advantages: metal workpiece surface after 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 through the hydraulic cylinder, the hardness can be increased by 15 to 30%, while the wear resistance is increased by 15%. Rolling surface roughness can increase from Ra6.3 to Ra2.4 ~ Ra0.2. And a higher production efficiency, some of the workpiece can be completed in a few minutes or a few seconds.
