Benefits of burnishing with SUPEROLL | Expand
Slight diameter sizing (in microns) without machining.
Smoothing out uneven workpiece surfaces allows dimensional amendment of several μm.
Mechanism: Sizing of ID
Machined peaks and valley are compressed evenly to increase hole size without stock removal.
Tool diameter and burnishing value
Set tool diameter dozen of μm larger (Burnishing value) than hole size before burnishing.
Sizing example: Hole expansion
