Threads of the highest surface quality can be produced with minimum machining times using the Wagner tangential rolling system.
The tangential rolling tool is mounted with the adapter on the tool carrier, e.g. turret disc. It moves with a constant feed onto the rotating workpiece. The thread rolls are set in rotation by touching the workpiece and form the thread as the tool carrier continues to feed. As soon as the thread rolls have reached the centre of the workpiece the rapid return is initiated and the workpiece is released. Optimum productivity is achieved using precise thread rolls with maximum tool life. The diameter, pitch and shape of the rolls are adapted to the thread to be rolled. Wagner tangential rolling tools are available in various sizes and are suitable for machining workpieces from Ø 1.6–52 mm.
Premium rolling results in fine-pitch threads can be achieved by using our tool variant “F”. For threads with very small pitches, it is important to keep the axial play of the thread rolls as low as possible. By means of the patented Wagner axial play fine adjustment, the axial roll play can be minimized in 0.02 mm steps. The fine adjustment is available as an option.
Profile rolls for special applications such as rolls for lubrication grooves, knurling or smoothing are also available.
