These vitrified wheels are formed so that the raceway (groove) and the rib (flange) of a bearing ring are ground in a single pass, which shortens cycle time and keeps the raceway-to-rib geometry consistent from part to part.
Using our composite forming technology, different abrasives and hardness grades can be combined in one wheel, so each zone of the profile gets the grinding behaviour it needs.
Different abrasives and hardness grades are formed into one wheel, each matched to a zone of the raceway. Wheel wear drops, life increases, and the load on superfinishing is reduced while profile accuracy improves.
