Skiving and Roller Burnishing: Combined Finishing for Deep Holes
I use skiving and roller burnishing for fast finishing of hydraulic cylinder bores. Skiving and roller burnishing is a combined process that cuts the bore to final size and then burnishes the surface in a single pass. It replaces honing on many applications and produces a mirror-like finish in less time. How the Combined Process Works The skiving head carries cutting inserts that remove the bulk of the stock. Behind the cutting inserts, a set of hardened rollers presses against the bore surface. The rollers apply high contact pressure that plastically deforms the surface peaks into the valleys. ...
