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.
Claims20
A system to finish a cylindrical member, comprising:
- a retainer to fixedly secure a cylindrical member, and configured to leave exposed a finishable area of the cylindrical member, the finishable area having a first cross-sectional area and a first roughness;
- a finishing tool having a body having an interior wall defining an opening extending therethrough along a longitudinal axis, the opening having a second cross-sectional area less than the first cross-sectional area, at least the interior wall having a surface hardness greater than a surface hardness of the finishable area of the cylindrical member,
- wherein in response to the opening of the finishing tool receiving the finishable area of the cylindrical member as the finishing tool is moved relatively closer to the cylindrical member at a relative force, the roughness of the finishable area of the cylindrical member is reduced to a second roughness.
A process to finish a cylindrical member, comprising:
- securing a cylindrical member to a retainer such that a finishable area of the cylindrical member is exposed, the finishable area having a first cross-sectional area and a first roughness;
- slidably contacting an interior wall defining an opening formed in a finishing tool over the finishable area of the cylindrical member at a relative force, the opening having a second cross-sectional area less than the first cross-sectional area, at least the interior wall having a surface hardness greater than a surface hardness of the finishable area of the cylindrical member such that the roughness of the finishable area of the cylindrical member is reduced to a second roughness.
A finishing tool to finish an outer surface of the cylindrical member, comprising:
- an interior wall defining an opening extending therethrough along a longitudinal axis, the opening sized to receive a cylindrical member, wherein the interior wall is configured to reduce a roughness of the cylindrical member;
- and
- an attachment portion.
