The production technology of skiving and roller burnishing  (also smooth rolling) is used for the manufacture of cylinder tubes. Among other aspects, the cylinder construction industry places great emphasis on resistance to internal pressure, such that the loss in customisation can be kept as low as possible. Of course, the focus of attention is on the quality of the bore. Here, the requirements of the piston seals are decisive for the required values of the surface roughness and diameter tolerances. Skiving reduces diameter deviations and ovality caused by the raw stock. The rolling, which takes place in the same process, ensures the required internal diameter tolerances and asperity values. Extensive series of tests by the well-known seal manufacturers have recognised rolling or even smooth rolling as a suitable production process for the seal running surfaces. However, the cost aspect is equally as important as the quality. Here, the great advantage of skiving and roller burnishing  is in the rapid production of the tubes, which primarily reduces the price compared with honing. A further advantage of skiving and roller burnishing  is in the long manufacture lengths that can be produced. We are able to produce tubes up to a length of 11.6 m, such that the loss in customisation can be kept as low as possible.
