Non-circular Spinning

The increasing trend of the individualization of products demands an advancing widening of the range of varieties of the goods on offer while at the same time lot sizes decrease. To handle the challenges this implies manufacturing needs to use technologies which allow for a flexible and effective production especially in the lower lot size segment. One process which fulfils these requirements is spinning. Low tool costs and short set-up times enable a flexible and cheaper production in the middle and lower lot size segment compared to conventional forming processes (e.g., deep-drawing). One way to further increase the economic relevance and flexibility of spinning is expanding the range of parts to be produced by non-circular spinning. In the following the process development of the socalled “non-circular spinning” with motion controlled rollers will be described.
