Description
Great effort is expended to keep friction reasonably low in wiredrawing. However, there are products and practices where friction cannot always be low. These include metals with passive layers (such as stainless steel) and certain bright drawing practices. This paper addresses process design modifications appropriate for such cases. While enhanced lubrication, per se, is not addressed in this paper, the engineering basics of die and pass schedule design adjustments and limits are considered, as well a friction-reducing tooling systems.
