As an example, a cold drawn tube may have to be drawn 34 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 ...

A cold pilger rolling tool for producing internally ribbed tubes uses a cold pilger step rolling process in a rolling stand that is movable back and forth in a direction of rolling and has rolls of a tapered design. The rolls of the stand roll along a material with an alternating direction of rotation. The tool includes a cold pilger rolling mandrel which tapers.
The problem of the geometry of the pass and, therefore, of the tool design assumes even greater importance in the rotary operations which are characterised by high levels of redundancy and consequently by very severe forming conditions.
