What is Pilgering - Pilger Mill Technologies

As an example, a cold drawn tube may have to be drawn 3-4 times to equal the same amount of work of a pilger mill. Each time a tube is cold drawn, the tube must be cleaned and annealed (softened) before drawing again. For producing very small quantities of tube alloys, cold drawing has the advantage with quick tool changes and low operational ...

Cold Pilger Rolling: Part One :: Total Materia Article

Figure 1: The scheme of cold pilger rolling. The two most common ways to cold-reduce tubes by compression are VMR1 and HPTR2 cold pilgering mills. Although both VMR and HPTR dies reduce tubes via compression rather than tension, the complexity of tooling design and manufacturing varies greatly between these machine types.
