The rolling steel tubes are mainly used in cutting and rolling, and a wide range of tools are used in machining. Most of these cutters can hold two to eight indexable inserts. At the rear of the cutters are rolling tools with four to fifty rollers. The rolling tube and polyurethane cushions are shock-resistant. In the actual processing, it can be divided into two types, one is boring, mirror rolling one feed to complete the processing; the other is to carry out boring first, and then the next processing.

If we want to use rolling processing, we mainly use cold plasticity of metal at room temperature to perform pressure finishing. The rolling tool will exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece will generate a plastic flow and fill in the valley of the original residual trough, and the surface roughness of the workpiece will be reduced.

The use of roller barrels is mainly based on the method of rolling, mainly through the process of broaching cylinders, boring cylinders, and rolling cylinders. Of course, this non-cutting process can not only improve the roughness of the workpiece surface, correct roundness, but also improve the hardness of the workpiece surface and eliminate the force deformation. This process can also provide residual stress layers after processing, increasing fatigue strength by 30%.
