What does a thread rolling machine do?

A thread rolling machine forms threads on a workpiece by plastically deforming the material rather than cutting it. This process involves pressing the workpiece between two or more hardened steel dies with the thread profile. As the workpiece rotates, the dies gradually form the desired thread shape.  

Key Advantages of Thread Rolling:

Improved material strength: The cold working process increases the material's hardness and fatigue resistance.

Higher production rates: Thread rolling is typically faster than cutting methods.  

Better surface finish: Rolled threads have a smoother and more uniform finish.  

Material savings: Less material is wasted compared to cutting methods.  

Common Applications:

Thread rolling is widely used in various industries, including:

Automotive

Fasteners  

Aerospace

Construction

Manufacturing
