  • Patent number: 5354071
    Abstract: A wear sleeve is formed from a tube which is expanded radially into a true cylindrical configuration and then machined on its inner and outer surfaces to improve the tube surface finish. The machining operations include machining V-shaped annular grooves at preselected locations along the tube. Wear sleeves are cut-off from the tube on radial planes passing through the grooves so that the grooves form chamfers on the ends of the wear sleeves.
