I. Introduction

Hydraulic and pneumatic cylinders rely on ultra-smooth surface finish tolerances for operation longevity. The skiving and roller burnishing action passes over the material with skiving knives to create a perfectly round bore. This is followed by rollers that cold-work the surface and compress remaining material left behind from skiving, which creates a residual stress coating. The result is a supremely smooth interior wall with a mirror-like finish. When this process uses reliable machines such as those developed by TechniDrill, the end product extends the life of cylinders.
