Cold Rolling

The friction generated between the rolling dies and the metal round bar,driven by high radial spiral pressure,causes the metal bar to undergo plastic deformation and be forced into the rolling zone.During this process,the external grains of the metal bar experience slip flow along the tooth profile contour of the dies,ultimately achieving the required thread dimensions.This process is known as cold rolling formation.

Turning 
This process utilizes a lathe cutting tool to machine a rotating metal round bar,ultimately obtaining the required thread dimensions as well as end shaft dimensions.

Grinding 
This method employs grinding wheels to abrade the metal round bar to obtain the required threads.It is typically used for screws made of harder materials(such as GCr15,40Cr,etc.)or for triangular thread lead screws.While this method offers high precision,it has relatively low production efficiency.
