MASTERING THREAD ROLLING – MATERIAL PREPARATION
Step one is important, once I realized it wasn’t posted, I got it posted right away. Why is material prep important with thread rolling? Thread rolling is a cold forming process and the material goes through a state change. With Axial rolling tools this change...
MASTERING THREAD ROLLING – MACHINE SETUP
The third step with proper rolling is the Machine Setup. Mount tool and sweep faceplate OD with an indicator – Rolling requires TIR of .005”
MASTERING THREAD ROLLING – TOOL SETUP
The second step with proper rolling is the Tool Setup. Mill a .250” to 375” flat on the shank within .500” of the head if not already there. The RORO tool is assembled and setup. The rolls are set with a gauge pin to the max Minor less a proprietary calculated amount...
