Skiving and Roller Burnishing Process

Skiving and roller burnishing is a two-in-one bore sizing and finishing process that delivers high levels of precision at lightning-fast speeds. Skiving and roller burnishing process is up to 70% faster than traditional honing, making it an ideal solution for finishing hydraulic cylinder tubes in mass-production environments.

High-Speed Finishing for High-Production Manufacturing

The skiving and roller burnishing process uses a unique combined skiving and roller burnishing tool that performs both skiving and roller burnishing in one pass through the bore.

The front section of the tool contains carbide cutters that remove material (skiving process). The second section of the tool contains hardened rollers that deform the peaks created by skiving and create an extremely smooth surface finish (roller burnishing process). The combination of these two processes creates a very fine surface finish with a typical RA of 0.05-0.20 µm.

Skiving + Roller Burnishing Is Typically Used To:

  • Improve surface finish—as fine as .10 – .15 microns (4 to 6 micro-inches) RA on average
  • Improve size control—tolerances within 0.0254 mm (.001 inch) on average
  • Increase surface hardness
  • Improve fatigue life

Typical Skiving + Roller Burnishing Applications Include:

Hydraulic cylinders/components for industries such as
  • Agriculture
  • Heavy-duty construction
  • Mining
