Thread rolling is a cold-forming or cold metal forming process that creates threads using the precision thread rolling dies that are the mirror image of the thread being produced. Thread rolling is a mechanical process where threads are cold-formed when the part is squeezed between two thread dies on a thread rolling machine. Thread rolling provides for a stronger thread and no loss of material.
However, thread cutting operation is done on a machine using a single-point tool called thread cutting tool. The workpiece is held between centers or in a chuck and the tool is held in a tool post. A cut thread (also called a machined thread) is made by machining away the material to create the thread form. Cut threads, as the name implies, are made by cutting away material.
