Thread-rolling  – it is the least expensive way to create a thread. Is carried out mainly on the blanks the hardness of which should be low, to carry out the process of thermal hardening. Therefore, this type of thread making stage is used only to create threads with low accuracy. Such threaded bank has high wear resistance and toughness. The process is up to provide thread-rolling on a metal surface by plastic deformation of the processed material. With this method of thread creating, swarf is not removed. In the treated core between the special cylindrical roller (or it may be a plate) with a thread profile is pressed out of a similar profile, and the item is rolled between them. The minimum diameter of the thread at thread-rolling is considered 1 mm, maximum - 200 mm.

Thread-rolling "Ukrenergoremont"

Manufacturing of  threads on the thread-rolling tools require complying with a list of specific requirements, which include low roughness, high performance, the accuracy etc. Thread Production method thread-rolling requires high professionalism, as to develop a high-quality manufacturing process of thread is quite difficult.

The process of thread-rolling has the following thread-rolling plastic deformation features:

- Causing substantial deformation of the material surface, whereby the treated metal is not destroyed;

- There is a significant hardening of the surface layers of the blank, thereby increasing the load capacity of the rolled parts.

Thread-rolling of Ukrenergoremont  improves the mechanical properties of the blank material, and in some cases eliminates the need for further heat treatment.
