Hydrostatic Deep Rolling Tools
Hydrostatic tools in the ECOROLL HG range are able to roller burnish, deep roll and roller compress the most complex contours and free-form surfaces within bores and external profiles.
The heart of the HG tool is a special ball of hard material which is hydrostatically mounted in a ball holder. The ball is pressed with a defined rolling pressure against the surface of the workpiece by the pressure medium, either oil or air, in order to shape the profile. The process induces residual compressive stresses into the boundary zone, increases the strength of the material and at the same time smooths the surface.
Applications
- Roller burnishing up to 65 HRC and deep rolling
- Increase fatigue strength for internal, external diameters and fillet radii
- Follow complex contours and free-form surfaces
- Range of ball sizes available
- Uses high-pressure oil or air
