Transverse Wedge Rolling


Transverse Wedge Rolling is a process in which a round billet is inserted between appropriately shaped rolls or flat plates that deform the workpiece as it rotates. These tools incorporate a wedge shaped profile, from which the process takes its name.

There are several versions of Transverse Wedge Rolling:

If rolls are used, they rotate in the same direction and drive the workpiece. Here either two or three rolls (figure1) can be used.
If flat tools are used, they move in opposite directions while rotating the workpiece between them.
A planetary system with a single large work roll and a fixed work segment is possible(figure2), or a concave-tooling segments can also be used.
