Method for manufacturing a flat friction disc

摘要

The method involves putting a sinter friction layer on a flat steel lamella (1) and then sintering it, before the sintered friction layer (2) is compressed and calibrated, with grooves (4) being pressed into it at the same time. During the calibration of the friction lamella, limited recesses (5), divided locally over the surface, are made in it through the sintered friction layer. These recesses in the sintered friction layer zone may be pressed through only at the bottoms of the grooves.
