ST52 Skived roller burnished tube and honed tube are the two kinds of production method for hydraulic cylinder barrel. As we all know, these two kinds of process will be chose when the barrel ID in different.
Producing ST52 cylinder tubes by honing results in having across-grinding pattern. The tubes in this case present an improved inside straightness. the Skived roller burnishing very precise and smooth surface reduce friction negative effects and extends the life of the cylinder’s components.
The skiving and roller burnishing production technique refers to a process consisting in micro-finishing metallic internal tube surfaces. The resulted effect is a mirror surface finish with technical roughness advantages. ST52 E355 Skived Roller Burnished Tubes are the most important material of manufacturing hydraulic cylinders. The skived & roller burnishing process is a single pass operation that uses a cutting tool (skiving knives) on the forward path, to remove the stock to machine to the specified dimension, and then uses roller bearings on the reverse stroke, to burnish the inside surface to achieve the highest surface finish tolerances.
