Radii Hydraulic Type

Tailor made tool for work hardening radii


Tailor made tool for radii
These tools are especially designed for work hardening (e.g. dynamically loaded fasteners in aerospace or racing applications). The required rolling force is applied hydraulically (by coolant pressure) or mechanically.



Application parameters

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

Speed up to 30 m/min
Lubrication emulsion or oil; filtration of the lubricant (<40 μm) can
improve the surface quality and the tool life
Premachining of workpiece surface roughness (Rz) up to 15 μm
Workpiece hardness up to 45 HRC


  1. very short machining time
  2. fast return of investment
  3. low machining forces
  4. easy to maintain
  5. both tool or workpiece can rotate
