The processing method of using forming and rolling molds to produce plastic deformation of threads on the workpiece. Thread rolling processing is generally carried out on the wire rolling machine and is suitable for mass production of external threads of standard fasteners and other threaded connectors.
According to the different thread rolling dies, thread rolling can be divided into two types: screw threading and thread rolling.
The advantages of thread rolling process:
1.The surface roughness is less than that of turning, milling and grinding.
2.The surface of the thread after rolling can improve the strength and hardness due to cold hardening.
3.High material utilization rate.
4.The productivity increases exponentially compared with the cutting process, and it is easy to realize automation.
5.Rolling die life is very long.
