What is a Thread Rolling Machine? – High-Quality Industrial Solutions

The thread rolling machine is a precision industrial machine designed to form threads on bolts, screws, studs, and other fasteners without cutting. Unlike traditional thread-cutting methods, thread rolling machines create threads through plastic deformation, resulting in stronger, smoother, and more durable threads.

As a professional manufacturer of CNC wire bending machines, we also specialize in providing high-quality thread rolling machines tailored for industrial applications, delivering precision, efficiency, and reliability for global buyers.

How a Thread Rolling Machine Works

Thread rolling machines operate on the principle of cold forming:

A metal blank (rod or wire) is fed into the machine.

The blank passes between specialized dies—flat, cylindrical, or planetary—which press and shape the threads onto the workpiece.

The process strengthens the material through work hardening, producing high-quality threads with minimal material waste.

This method ensures fast production, consistent thread accuracy, and a smooth surface finish, making it ideal for high-volume manufacturing.

Types of Thread Rolling Machines

Flat Die Thread Rolling Machines

Uses two flat dies to roll threads onto bolts, screws, or rods.

Suitable for medium-sized fasteners.

Widely used in general industrial and workshop applications.

Cylindrical (Round) Die Thread Rolling Machines

Uses rotating cylindrical dies to form threads.

Ideal for high-volume production with uniform thread quality.

Perfect for automotive, construction, and hardware industries.

Planetary Thread Rolling Machines

Uses a planetary gear system for high-speed thread forming.

Designed for small screws, pins, and precision components.

Offers rapid production with excellent accuracy for automotive and electronics applications.

Applications of Thread Rolling Machines

Thread rolling machines are essential in industries requiring high-strength and precise threads, such as:

Automotive Industry: Engine bolts, chassis fasteners, and studs.

Construction: Anchor bolts, threaded rods, and structural fasteners.
