  • Publication number: 20150128392
    Abstract: A tool, system, and process for finishing a cylindrical member is provided. The finishing tool includes an opening. The opening is sized to receive a cylindrical member. The interior wall of the tool opening is configured to reduce a roughness of the cylindrical member. The opening has a second cross-sectional area that is less than the cross-sectional area of the member. A retainer can secure the member. In response to the opening interior wall slidably contacting a finishable area of the member as the finishing tool is moved relatively closer to the member at a relative force, the roughness of the finishable area of the member is reduced to a second roughness.

  • Patent number: 8511130
    Abstract: A method for preventing or arresting the development and propagation of cracks in the material surrounding a fastener. The method includes introducing compressive residual stresses in the material surrounding the fastener. The compressive residual stresses offset the high residual tensile and applied stresses which the material may be subjected to in operation and thereby prevent or arrest the development of cracks. Using the output of a sensor, the surface treatment apparatus is positioned relative to a fastener. A compression tool is impinged against the surface of the material adjacent to the fastener and rotated around the perimeter of the fastener thereby inducing a zone of compressive residual stress.

  • Patent number: 8250720
    Abstract: There is disclosed a roller burnishing apparatus including a first member moved relative to an object to be burnished, a second member movable relative to the first member in a relative movement direction, a burnishing roller held by the second member such that the burnishing roller is rotatable, a biasing device which biases with a biasing force the second member relative to the first member in one of two opposite directions along the relative movement direction, and a pressing-force detecting device that detects a pressing force with which the burnishing roller is pressed against the object and which is based on the biasing force of the biasing device.

  • Patent number: 8024846
    Abstract: A method for preparing a surface includes providing an article having an article surface, thereafter first processing the article surface to establish a first residual compressive stress state and a first surface roughness in the article surface, and thereafter second processing the article surface by surface compressive texturing to establish a second residual compressive stress state and a second surface roughness in the article surface. The second surface roughness is quantitatively less than the first surface roughness, and substantially no material is removed from the article surface in the step of second processing.

  • Patent number: 7188398
    Abstract: This invention relates to a method and an apparatus for performing the method of inducing compressive residual stress along the surface of a part. In the preferred embodiment of the invention, the method includes burnishing or deep rolling a surface using a first and a second roller or ball burnishing members, whereby the first and second burnishing members may have a different diameter and/or modulus of elasticity. In another preferred embodiment of the invention, the burnishing operations may be performed while the surface of the part is at different temperatures.

  • Patent number: 6651298
    Abstract: A lithographic printing plate substrate web is brush grained with some of the brushes having the bristles moving over the web along a first track and some additional brushes having the bristles moving over the web along a second track at an angle of at least 5° to the first track. Some of the brushes may have the axis of rotation perpendicular to the direction of movement of the web in the conventional manner and at least one additional brush having the axis of rotation at an angle to the direction of movement of the web. There may be a plurality of such additional brushes, usually two, with the additional brushes being angled with respect to each other. In one embodiment, the bristles of the additional brush track over the web in a direction perpendicular to the web movement.

  • Patent number: 6468133
    Abstract: The present invention concerns a method for treating the surface of a fibrous web by mechanical grinding. According to the invention, the grinding is performed at substantially dry state by removing only the higher parts of the paper surface without substantially increasing the density of the web. By reducing the roughness of the surface by a maximum of 90%, the strength properties of the web remain essentially unchanged or they are even improved. Thus, when the roughness of the surface is reduced by about 40 to 60%, the tear strength increases with more that 5% in comparison to an untreated web. Papers and boards treated by the present method can be used for printing, packaging and wrapping.
