2.2.7 Thread Forming
Equipment: Thread rolling machines, thread rolling dies, thread forming machines, thread forming plates, tapping machines, taps, etc.
Thread Forming Methods: Thread rolling, thread forming, tapping, etc. Among these, thread rolling and thread forming are mainly used to produce external threads, while tapping is used to create internal threads.
Thread Rolling / Thread Forming: Achieves threads by squeezing and displacing the material, used for manufacturing external threads, such as the threads on bolts.
Tapping: Achieves threads by either squeezing or cutting the material, used for manufacturing internal threads, such as the threads in nuts.
