7 Special applications
7.1 Rolling tapered threads
Several points must be considered when rolling tapered threads.
1. Adjusting the distance between the axes:
To adjust the distance between the axes (see also Chapter 5.1.5), place the setting
gauge (ET-32)
3
in the region of the largest roll diameter between the two thread
rolls (ET-18), see Figure 20-left. Adjust the distance between the axes with the set
screws (ET-30) until the setting gauge in this region fits exactly between the thread
rolls.

2. Adjusting the traverse paths:
Figure 20-right shows the workpiece (2) in the collet (4) of the machine spindle.
To adjust the rolling position (see also Chapter 6.3) for a conical thread, it must be
ensured that the setting gauge is touching the workpiece (2) at the reference plane
(3) of the tapered thread. This is located on the workpiece at the distance a from
