Technical details: Rolling unit for external use



Modular single-roller burnishing tool for external use

Application cylindrical shafts also against shoulder, plane surfaces
Diameter range from 15mm, due to the rolling forces during the process, the stability of the workpiece and the clamping has to be ensured (e.g. by using tailstock or rest)
Rolling unit
(4 rollers)
with 4 small rollers (one roll in process), – lower rolling forces, quick and easy change of the rollers by rotating the cage in steps of 90° without removing the tool out of the machine
Rolling unit
(1 roller)
with 1 bigger roll, – higher processing speed, and higher lifetime


Application parameters

Please note that this information represents standard values which must be adapted to the individual cases.

Speed up to 200 m/min
Feed rate 0.05 — 0.3 mm/rev
Workpiece allowance up to 0.03 mm
Tool pre-load up to 1.5 mm
Lubrication emulsion or oil; filtration of the lubricant (< 40 μm) can improve the surface quality and the tool life
Pre-machining of workpiece surface roughness up to 15 μm
Workpiece hardness up to 45 HRC


Modular single-roller burnishing tool system
Rolling unit for smoothening and work hardening shafts.



  • processing cylindrical shafts also against shoulder
