ATTENTION
The determined blank diameter must be maintained with a tolerance of
± 0.015 mm l 0.0005 inch!
The chamfer angle should be γ = 10 … 30°. The inner diameter d

should be below the
thread core diameter d

A chamfer angle γ = 30° produces a chamfer of approx. 45° after rolling on the work-
piece.
NOTICE
Larger chamfers significantly reduce the tool life of the thread rolls.
5.2.2 Placing the rolling head into the holder
Install the rolling head holder on the machine tool. Insert the tangential rolling head
into the rolling head holder. To do this, proceed as follows (see also Figure 14):
■ Loosen the set screws (ET-31-12) on the rolling head holder
■ Pull the axis (ET-31-4) sideways out of the rolling head holder
■ Slide the rolling head between the two brackets of the holder and insert the axis
(ET-31-4) through the rolling head holder and through the rolling head on the bush-
ing (ET-4)
■ Check whether the rolling head can pivot freely about the holder axis
■ Retighten the set screws (ET-31-12)
