S.C.A.M.I.® Roller Burnishing Through Hole    360 Icon
Roller burnishing is a cold-working process which produces a fine surface finish by the planetary rotation of hardened rolls over a bored or turned metal surface. This process provides a more effective method of sizing, finishing, and work-hardening of your parts to exact specifications.

Advantages
  • Provides versatility because the operation can be performed on any rotating spindle
  • Provides accurate size control with tolerances within 0.0005" or better (depending on variables such as material)
  • Achieves fine surface finishes between 1-10 µin Ra and increases surface hardness by 5-10%
  • Improves metallurgical properties
  • Replaces grinding, honing, lapping and other expensive secondary options
Features
  • Diameter range: 0.1555" - 6.5315" (3.95mm - 165.90mm)
  • All roller burnishing tools are composed of the basic burnisher assembly, including cage, cone, rolls, and shank (either straight or Morse Taper)
  • In some cases, there will be a diameter overlap between a series and the series after it. If the diameter you need falls into this overlap, choose the higher of the two series.
  • For example, you need a 24.64mm diameter tool. This diameter falls into both the K series (16.60mm - 24.74mm) and the L series (24.54mm - 31.16mm). In this scenario, you would choose the L series tool that covers the 24.64mm diameter.
