A method and compression roller tool for increasing the strength of load-bearing surfaces on shafts, in particular on crankshafts, which surfaces are pre-machined with the removal of chips, wherein the cylindrical surfaces of the main bearing journals and pin-bearing journals and optionally also the journal of crankshafts have additional oil bores. At least one of the load-bearing surfaces is compression-rolled by way of at least one cylindrical body which has a surface structure and extends over the width of the load-bearing surface. Afterwards, the compression-rolled load-bearing surfaces are machined with the removal of chips with a low chip depth. The compression roller tool consists of a cylindrical compression roller body and a supporting body opposite it, wherein the compression roller body has thickened portions on its cylindrical surface, which thickened portions run either in the circumferential direction or in the axial direction or diagonally with respect to the axial direction.

An embodiment of a tool assembly includes a hub connected to a distal end of a spring-loaded shaft assembly disposed along a first axis. An upper hub portion is adjacent to the distal end of the spring-loaded shaft assembly aligned with the first axis, and a lower hub portion extends along a second axis, forming a nonzero angle relative to the first axis. A roller disk is joined to the lower portion of the hub, and is rotatable about the second axis parallel to the second portion of the hub. A load cell is disposed along the first axis between a proximal end of the shaft and the roller disk, and is adapted to measure a downward force applied along the shaft assembly.

The invention relates to a hard-rolling roller for a deep rolling tool having a torus-shaped base body for deep rolling of radiuses or recesses which limit the bearing trunnion on crankshafts on both sides, and two at least approximately truncated cone-shaped central bodies, rising on both sides of the body. A cylindrical body rises on the upper end surface of one of the two central bodies.

A honing assembly, a sanding assembly and a turning machine for performing an operation on a workpiece. The turning machine may include a rotatable machine housing operable to rotate around the workpiece; a first attachment including a first portion engageable with and operable to remove material from a workpiece, the first attachment having a first configuration, such as a honing attachment; and a second attachment including a second portion engageable with and operable to remove material from a workpiece, the second attachment having a second configuration, such as a sanding attachment, different than the first configuration, each of the first attachment and the second attachment being selectively supportable one at a time by the machine housing to operate on a workpiece.

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.
