    摘要: A honing head for microburnishing surface of a recording/reproducing disc to a smoothness at which asperities are limited to submicron heights including a hardened contact bearing surface having an array of depressions with abrupt trailing edges interconnected by recessed channels leading outwardly from the honing head. The array of channels span a band in which an asperity may be present, and the sharp edges shear off the asperities within the band which extend above the chosen submicroinch height, with the separated particulates being passed through the recesses and channel system to the outer edge of the honing head. The trailing edges act to shear off the unwanted heights of the asperities, while the recesses enable pressure differentials and air flows to direct the separated particulates outwardly relative to the disc, centripetal forces of rotation bearing the particulates from the disc. A diamond-like coating on the entire contact bearing surface and the recesses aids in reducing wear and the stiction of the smooth surfaces to the disc that is being burnished. This arrangement has the further advantage that the honing head may be prepared by photomicrolithographic techniques to generate the array of recesses on a production basis, with the recesses having precisely determined depths and perpendicular trailing edge walls. Ion milling and other known techniques can be used to remove the materials in the chose patterns quickly and efficiently.

    摘要: An edge-finishing device comprises a drive unit (L), a holder (M) and a notched tip (N). The tip combines a number of geometric features known as land radius (Y), flank faces (K), flank radii (I) and root radius (J). Typical useage of the device requires a tip to be fitted into the holder, the tip being then offered against the workpiece using the flank faces for guidance. The land radius determines the contact area. The tip impacts against the workpiece and bends the protrusions over. The flank radii then beat the protrusions thin enough for them to break off or be driven off. The tip continues to impact until the finished edge conforms to the root radius.

    摘要: A method for repairing a compressor blade of a turbine engine, the blade including a cat's tongue at the radial end thereof, the radial extension of which is less than a predefined nominal radial extension. The method includes elongating the cat's tongue via a cold-compacting operation applied to the walls of said tongue, such that the radial elongation thereof becomes greater than the nominal extension. The compacting operation is a roller-burnishing operation carried out by moving the end of the blade between two rollers having rectilinear generatrices and spaced apart by a distance smaller than the thickness of the cat's tongue, along the chord connecting the leading edge with the trailing edge thereof.
