Abstract

See full text

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.
