T2 Refining

Process combination micro rotary swaging/ micro impact extrusion 

The transfer project "Refining" dealt with the conditioning of wire semi-finished products by micro rotary swaging for following forming processes. On the one hand the exact calibration of the diameter, the generation of a suitable surface and the improvement of the straightening were of interest, on the other hand the development of an ultra-fine-grained structure, which favors the following cold forming processes was to be achieved. By means of modifications of the process kinematics and the tool geometry for the micro rotary swaging process, our industrial partner was able to continue processing difficult formable materials. The success of the realized methods was demonstrated by the industrial production of microscrew.
