How do rolling machine threads work?
Sep 09,2025
A thread rolling machine produces threads on bolts, screws, studs, or rods without cutting the material. Instead, it uses plastic deformation to form the threads, which makes them stronger, smoother, and more durable than cut threads. At Yushi, we specialize in manufacturing CNC wire bending machines and high-quality thread rolling machines. Our equipment is designed to deliver precision, efficiency, and durability for industrial wire and fastener processing.
The Working Principle of Thread Rolling Machines
Feeding the Blank
A metal rod, wire, or blank is fed into the machine.
The blank is typically straightened before threading to ensure uniform results.
Die Engagement
The blank passes between specially shaped thread-forming dies.
Dies can be flat dies, cylindrical (round) dies, or planetary dies, depending on the machine type.
Thread Formation through Rolling
The dies press or roll against the blank, displacing the metal to form threads.
No material is removed; instead, the metal flows into the thread shape.
Work Hardening
The metal undergoes plastic deformation, which strengthens the thread surface.
This results in higher tensile strength and improved fatigue resistance compared to cut threads.
Finished Product Ejection
The machine ejects the threaded part, ready for use or further processing.
