Thread rolling machines are efficient machines for chipless processing of threads, splines, etc. In two-roll machines, the rolls rotate in a synchronized motion in the same direction, burnishing the thread or spline on the cylindrical surface. Rolling threads or splines is a more efficient and faster method than cutting them.

Rolling threads or splines is a more efficient and faster method than cutting them. Two-roll mills are used to make threads in solid materials, while three-roll mills are used to make threads on pipes. The TRM28-6.3A and TRM28-12.5 machines are blind machines and enable threading with the plunge method. The remaining two-roll machines are pass-through devices - they have tilting rolls - which allows making a thread longer than the width of the tools.
