Dressable vitrified bond cBN grinding tools combine the advantages of other common tool systems in
generating gear grinding. The cBN grains are a highly productive cutting material due to their high specific
stock removal rate. Vitrified bonds are dressable and thereby very flexible: By dressing different profile
modifications can be set up and constant gear quality can be guaranteed during the tool life time. Despite
those technological advantages there is only a small market distribution of these grinding tools due to
high tool costs. Furthermore, only a few published scientific analysis of generating gear grinding with
dressable cBN exist. Especially, the influence of the grinding tool system on manufacturing related
component properties has not been analyzed yet. The research objective of this report is to determine the
advantages of dressable cBN tools in generating gear grinding.
