Rolling deburring discs are used for creating chamfers on the teeth at both faces of the gear. Rolling deburring discs are available with an additional smoothing disc to minimise waste on the faces of the gear workpieces. Various chamfer versions such as: - Parallel, - Comma-shaped or - Parallel with chamfers at the root of the teeth are also available with face-bevelled workpieces. The tools are supplied already presetted and can be used for chamfering gears with the same gearing parameters and the same tooth width, if there is no risk of collision with the workpiece contour. Economical use of tools is guaranteed with the option of reversing the rolling deburring discs. When the wear limit of the rolling deburring discs is reached, the discs can be reversed and set up again in a very short time to re-use the tool.
