Skive and Roller Burnishing is a modern process to rapidly finishing the interior diameter (ID) of a tube to a cylinder quality size and finish.  A Skive and Roller burnishing tool uses a floating carbide cutter that produces a true round bore in the Skive operation and a work hardened seal friendly surface in the Roll operation.

Skiving in itself is a process used to remove stock where close tolerances and roundness are required.  Skiving produces a surface finish of approximately 60 to 125 micro-inches center line average (CLA). The depth of cut can range from as little as 0.002 inch per side and as much as 0.040 inch per side depending on the size of the tool.  However best results come from material produced specifically for Skiving.   Skiving also produces optimal peak and valley patterns for subsequent roller burnishing.

Commercial Fluid Power can be provided material in the Skived Only condition. A Skived tube will have a tighter tolerance than available through DOM or Seamless tubing products.   A Skived Only condition can be used to reduce costs by leaving minimal stock to clean up the ID after a weld operation or when a Skive and Rolled finish is not desired.  It can also be used to remove excess stock quickly and efficiently.

Roller Burnishing can follow the Skive operation.  This operation employs rollers which causes material to flow from the "peaks" into the "valleys". The burnishing process produces a more condensed and refined surface finish which reduces seal friction and surface porosity. A surface finish of 12 Ra or better is common.

Skived Only Advantages:

• 1. Faster processing than conventional rough or swipe honing.
• 2. Reduced roughing costs.
• 3. Reduced finishing stock after welding.
• 4. Reduced stock removal for finish honing.
• 5, consistent size end for end.

Skive and Roller Burnishing Advantages:

• 1. Faster processing than finish honing operation
• 2. Reduced finishing costs.
• 3.  Harder surface finish by up to 10 points HRC.
• 4. Work harder wear surface improves seal life.
• 5. Improved corrosion resistance.
• 6. Consistent size end for end.
