  • Patent number: 6726551
    Abstract: A manual knife sharpener is provided with angle control structure. The structure includes a guide member having a guide surface which forms an angle with the abrasive surface of the sharpening member. When the blade is inserted into the space between the abrasive surface and the guide surface the blade presses against the guide surface to displace the guide surface linearly in a direction perpendicular to the guide surface so that the movement is a lateral movement in the same plane without any pivoting or twisting of the guide member. Thus, the angle between the guide surface and the abrasive surface remains constant regardless of the extent of displacement of the guide member.

    Abstract: 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.

    Abstract: The present invention is directed at a method and an apparatus for finishing an orifice surface of a work piece consisting of a hard material such as ceramics or glass. The method removes surface anomalies on the orifice surface with a broach to produce a finished orifice. The broach tapers from a broad end down to a narrow end. The cross-section at the broad end is sized to fit snugly in the finished orifice. The method involves inserting the narrow end of the broach through an orifice of the work piece, and passing the broach through the orifice. In this way, the broach files and thereby removes the surface anomalies to conform the orifice to the finished orifice.
