Upon repeated resharpening the precision of the hob would be lost if the relief of hob teeth was not carried out correctly. To maintain the precision possessed by the new hob, the relief grinding must ensure an unchanged profile angle along the teeth. This requirement can be achieved only by correct set up of the grinding machine.
