Vitrified bonds are usually used for this special type of grinding wheels. Depending on the grinding operation, the grinding wheel for bearing seats can be composed of one single layer or of three layers, in case the shoulders and the bearing seat are to be ground in one passage. We are able to manufacture these multi-layered grinding wheels very precisely. Due to the three-layered version, the durability of your crankshaft grinding wheel is increased thanks to the enhanced stability. The low manufacturing tolerances of the motor manufacturers bear witness to our know-how.
