LATEST TECHNOLOGY FOR SPLINE ROLLING ON HOLLOW SHAFTS

In order to reduce weight, hollow shafts are increasingly being used in drive train systems. So far, such shafts could only be splined with the conventional cross rolling process up to a certain minimum wall thickness. In case of extremely thin-walled workpieces, more cost-intensive spline manufacturing processes had to be planned. With our newly developed reverse rolling process, the forming process itself takes a bit longer. But it´s possible to form splines on hollow shafts with wall thicknesses of up to less than 3 mm.

In the case of partial hollow shafts, processes can also be combined appropriately in order to achieve the most ecconomic cost-effectiveness.
