Thread rolling is a process that causes plastic deformation of metal materials through mechanical extrusion to form threads. 

The core principle is to apply pressure to the metal billet by using the concave-convex die structure of the thread rolling die, 

and through the lateral reciprocating motion, the material undergoes plastic flow, forming spiral grooves. ‌

Process principle:

The thread rolling machine is composed of a moving thread rolling plate and a static thread rolling plate, which are arranged opposite each other at a specific Angle. 

When the billet is squeezed between two plates, the metal undergoes plastic flow under the action of pressure and friction, eventually forming precise threads. 

This process does not require metal cutting and  directly forms through compressive stress, featuring high efficiency and good thread strength. ‌

The following conjunctions are included in the terminology system of mechanical processing:

screw plate: A mold assembly with a specific thread tooth profile thread rolling machine: A specialized equipment for implementing the thread rolling process

preformed strand wire: The form of raw materials in which the wire rolling process is applied automatic thread rolling machine: A type of equipment that realizes continuous production

Application fields:

It is mainly applied to the mass production of standard fasteners, including thread forming of bolts and screws

Surface processing of precision shaft parts

The preparation of pipe end threads by this process can increase efficiency by 10 to 15 times compared with traditional turning processing, and the cold work hardening of the processed surface can enhance the fatigue resistance of the threads

Equipment and Parameters:

Commonly used equipment includes manual, CNC and electric thread rolling machines. Before production,

 the equipment parameters (such as tension, speed, and mold model) need to be adjusted according to the

 material properties (such as diameter and hardness) to ensure processing accuracy. ‌
