The basic principle of Skiving Roller Burnishing is where the skiving tool (a modified floating reamer) produces a geometrically true round bore, which is a prerequisite for successful roller burnishing. To date, this process has proven to be the fastest method of ID finishing of seamless tubing, with average rates of metal removal of 500mm up to 1000mm per minute.

Due to specific industry demands, the Skiving/Roller Burnishing tool assembly has become a combination Reaming/Skiving/Roller Burnishing tool assembly, capable of removing up to as much as 6mm total stock removal in one operation.

Offers a full range of individual or combined Skiving/Roller Burnishing tool assemblies starting at 40mm up to 350mm diameter, and for cylinder lengths up to 12m long. Due to productivity and accuracy demands, this Skiving Roller Burnishing tooling is mostly utilized on stand-alone deep hole drilling machines.

• I.D. Burnishing Tools ranging from 40 – 350mm diameters.
• Improved surface finish – as fine as Ra 0.2-0.4 on average.
• Improved size control – tolerances within 0.05 mm on average and much finer for special applications.
• Increased surface hardness – up to 5 to 10% or more.
• Improved fatigue life – as much as 300% or better.
• Enhanced corrosion resistance.
• Elimination of tool marks and minor surface imperfections.
• Replaces expensive secondary operations, such as grinding, honing, or lapping.
• Cleaner than honing or other abrasive operations.
• Faster production, at a lower cost, as compared to other ID finishing processes.
• This process has recently been accepted as an alternate method of ID finishing by other than the hydraulic cylinder industry.
