Burnishing tool for deep rolling of dynamically stressed external threads
In the case of cut threads, the course of the grain of the workpiece is interrupted. With rolled threads, on the other hand, the grain flow is not interrupted, thus the surface of the thread is hardened and the workpiece is less sensitive to notch effects. With the Baublies single roller tool for deep rolling of radii on threads, an increase in the dynamic strength properties can be achieved. The tool rolls the core radius of an external thread and thus hardens the surface. The result is higher wear resistance and reduced notch sensitivity.
ADVANTAGES
- Different roller geometries possible
- Easy replacement of the rollers
- Short processing times
- No set-up and transport costs
