Technical data

Application external threads, deep rolling root of thread
Fixture as required
Path indicator housing heck path indicator (no force indication!) / default setting 1 kN preload
roller radius as required

Parameters

Speed up to 200 m/min
Feed rate according to pitch
Workpiece allowance up to 0.02 mm
Tool preclamping up to 2 mm
Lubrication Emulsion or oil; filtering the lubricant (< 40 μm) can improve the surface quality and service life of the tool.
Pre-machining of workpiece Surface roughness up to Rz 15 µm
Workpiece hardness 45 HRC

In the case of cut threads, the course of the fibre of the workpiece is interrupted. With rolled threads, on the other hand, the fibre 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 the notch effect is minimized.

ADVANTAGES

  • Different roll geometries possible
  • Easy replacement of the rollers
  • Short processing times
  • No set-up and transport costs
