What is Thread Rolling Machine?

A thread rolling machine is a machine tool used to create threads on a workpiece. It works by pressing a hardened die against the surface of the workpiece, which is shaped to match the desired thread form. The die and workpiece are then forced to rotate together, which causes the material of the workpiece to be plastically deformed and formed into the shape of the thread.

Thread rolling machines can produce threads on a variety of materials such as metals, plastics, and composites, and can be used to create threads on both external and internal surfaces. They are typically used to produce threads on rods, bolts, screws, and other fasteners, as well as on other parts such as gears and shafts. They are commonly used in mass production operations where high precision and speed are required.

There are different types of thread rolling machines, including flat die thread rolling machines, which uses a flat die that is pressed against the workpiece, and cylindrical die thread rolling machines, which uses a cylindrical die that is pressed against the workpiece. Depending on the type of machine, it may be capable of producing a variety of thread forms such as metric, unified, and acme threads.

Thread rolling machines have several advantages over other threading methods such as cutting or grinding, as they offer a high degree of precision and are able to produce threads with a high surface finish, they are also faster, less costly and require less material as well. Also they can produce threads in hard materials that can’t be cut with traditional methods and it doesn’t remove material from the workpiece.
