If the threads are produced on a CNC machine, the use of the die holder with compensating system is necessary. The function "rigid tapping" don't suit the rolling.

ROLLING OF SPECIAL PROFILES

Turning diameter before the thread rolling operation

We notice now and then that there are some problems with the use of our dies, bound to the start. When our dies are used on cam-controlled machines, please remember that the use of the starting cam is very important. Contact us or it can be calculated according to our service instructions (chapter 7).

The turning diameter before a thread rolling operation corresponds theoretically to the diameter of the thread flange. It is better to begin the job by reducing that diameter and by adjusting firstly the thread rolling die according to the control gauges (go and no go) and only then to adjust the turning diameter as per service instructions, chapter 5.3.

Diameter of flange = outside threading diameter - (0.649 x pitch)
