  • Composite honing ring
    Patent number: 6273801
    Abstract: The invention relates to a composite honing ring comprising a honing part and a carrier part, whereby both components are made of different materials and can contain plastic resins in particular. The invention is characterized in that the abrasive honing part (1) has a low porosity, especially less than 5%, and preferably contains fibrous reinforcing elements. The carrier part has higher elasticity than the honing part. Since the carrier part is elastic, it damps machine vibrations and bearing vibration received by said carrier part.
