1. A method for manufacturing a synchronizer ring for synchronized manual transmissions, characterized by the following steps:

  • a) producing a conical friction surface;

    which occurs beforeb) incorporating axial grooves having edges and a depth into the friction surface by chipless machining wherein a tool is axially shifted relative to the friction surface to produce a final friction surface;

    which occurs beforec) vibratory grinding of at least the friction surface; and

    d) subsequent hardening of at least the friction surface after vibratory grinding of at least the friction surface.
