WHAT IS COLD ROLLING?

Drill pipes undergo repeated,severe tensile stresses during a drilling operation. These cyclic stresses are particularly focused on the thread roots and can cause premature pipe failure. Cold Rolling is a method in which the threads roots of the material is compressed. The amount of force we introduce controls the hardness and other properties of the finished product; the endurance limit to bending forces is increased, thereby decreasing fatigue.

Salient Features

Thread Rolling Machines used for producing screws, bolts and tools. Thread rolling is a cold-forming operation only for external screws threads in a blank. The blank is pressed by thread rolling dies which are attached to the thread rolling machine.

Modern thread and profile rolling offers many advantages in the production of a wide range of solid and hollow components, compared to traditional metal cutting methods. Threads and profiles are stronger, consistently accurate and there is no swarf. When solid components are produced, the form is rolled from a blank with a smaller diameter than the finished piece; with hollow products the starting diameter can usually be maintained or allowed to increase as required.
