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.

Abstract
A synchronizer ring (10) for synchronized manual transmissions is manufactured by forming or reshaping a flat material of metal, wherein a conical friction surface (20) is produced, into which axial grooves (24) are incorporated by chipless machining, wherein a tool is axially shifted relative to the friction surface (20) to produce the final friction surface (20). At least the friction surface (20) is vibration-ground and subsequently hardened.
