摘要： A rolling component has a surface. The rolling component includes a fiber flow and a non-metallic inclusion. In a region from the surface of the rolling component to a first depth, a gap between the non-metallic inclusion and a member forming the rolling component is filled. The first depth is 50 μm or more. The surface and the fiber flow form an angle of 15° or more.

摘要： A burnishing machine is provided in which both sides of a groove is machined by a single tool without changing the movement direction of a piston.The burnishing machine, includes: a tip configured to press and process a process face; and a pressurizing unit configured to press the tip against the process face, the pressurizing unit including, a piston configured to reciprocate in a direction orthogonal to the tip, a cylinder portion that accommodates the piston such that the piston reciprocates; and a pressurizing mechanism configured to urge the tip to the process face at both timing of pushing the tip against the process face and pulling the tip against the process face by making the piston reciprocate.

摘要： An embodiment of a tool assembly includes a spring-loaded shaft assembly disposed along a first axis, a hub, and a roller disk. The hub is connected to a distal end of the spring-loaded shaft assembly. The hub has an upper hub portion adjacent to the distal end of the spring-loaded shaft assembly aligned with the first axis, and a lower hub portion extending along a second axis. The second axis forms an angle relative to the first axis. The roller disk is joined to the lower portion of the hub, and has a working surface about its perimeter. The roller disk is rotatable about the second axis parallel to the second portion of the hub. The working surface includes a profile along its width such that an effective radius of the roller disk varies along a width thereof.

摘要： Internal and external screw thread burnishing assemblies are provided. In the internal screw thread burnishing assembly, diametrically opposed removable cartridges carrying burnishing wheels are received in cavities of a support structure axially movable into the space circumscribed by the internal screw thread. Fluid pressure is utilized to forcibly translate the cartridges radially outwardly to place their burnishing wheels into burnishing engagement with the internal screw thread, with a spring structure resiliently biasing the cartridges toward retracted orientations thereof within the support structure. In the external screw thread burnishing assembly, burnishing wheels are carried on the outer ends of pivotally supported arms which may be pivoted by fluid pressure to drive the burnishing wheels into burnishing engagement with diametrically opposite portions of the external screw thread, with a spring structure resiliently biasing the arms pivotally away from one another.

摘要： The invention discloses a hard-rolling roller head with two separate housings for deep rolling the outside radii of adjoining crankpins of a split-pin crankshaft. The hard-rolling roller head provides an effective support of the two housings against one another, when machining split-pin crankshafts, and simultaneously prevents the upper areas of these housings from drifting apart.

摘要： An automotive shaft fillet treating method including laser hardening a green machined fillet surface to a uniform depth d to induce compressive stresses into the surface, the surface extending the entire length l between outer edges of two undercut regions of the fillet, and applying additional compressive stress to the laser hardened surface via fillet rolling such that the uniform depth d is maintained along the entire length l during a subsequent grinding operation.
