1. Introduction
The thread rolling machine is mainly used to produce screw thread. Like the cold heading machine, the thread rolling machine is also a cold-forming machine: During the forward movement of the machine, a stationary die and a moving die positioned opposite one another, roll the thread on the blank. For this reason, this thread rolling machine is also known as a flat die thread rolling machine.
