Systems and methods for producing battery parts, such as battery parts, are described herein. In one embodiment, a battery part machine is configured transform a profile of one or more acid rings on a battery part from a first cross-section to a second cross-section. The machine can include a rotatable spindle configured to receive the battery part, and a first tool and a second tool configured to engage the battery part. The orientation of the first tool and the second tool can be configured to engage the battery part at adjustable to polish, crimp, flare or otherwise transform the profile of the acid rings thereon to produce a finished battery part. An operator can input operating parameters to a machine controller to adjust the finished profile of the acid rings produced by the machine without requiring disassembly thereof.

1. A method of manufacturing a battery part, comprising: receiving a battery part that includes a sealing ring with a profile having a first cross-sectional shape;rotating the battery part;moving a tool having a forming portion toward the battery part; andengaging the sealing ring with the forming portion to transform the profile from the first cross-sectional shape to a second, different cross-sectional shape. 2. The method of claim 1 wherein the rotating occurs a predetermined number of times. 3. A method of manufacturing a battery part, comprising: receiving a battery part that includes a sealing ring with a profile having a first cross-sectional shape;rotating the battery part;moving a tool having a forming portion toward the battery part in a first direction; andengaging the sealing ring with the forming portion to transform the profile from the first cross-sectional shape to a second, different cross-sectional shape, wherein engaging the sealing ring with the forming portion includes moving the battery part in a second direction and an opposite third direction a predetermined number of times, and wherein the second and third directions are perpendicular to the first direction. 4. The method of claim 1 wherein moving the tool toward the battery part includes moving the tool in a first direction, and wherein engaging the sealing ring with the forming portion includes incrementally moving the tool in the first direction and in an opposite second direction a predetermined number of times. 5. The method of claim 1, further comprising inserting the battery part into a burnishing head. 6. The method of claim 1, further comprising polishing the battery part prior to engaging the sealing ring with the forming portion of the tool. 7. The method of claim 1 wherein the second cross-sectional shape includes an undercut. 8. A method of manufacturing a finished battery part, comprising: rotating a battery part on a spindle having a longitudinal axis, the battery part including a sealing feature having a profile with a first cross-sectional shape;moving a tool having a forming portion toward the rotating battery part, wherein the tool has an axis of rotation, and wherein moving the tool includes moving the axis of rotation toward the rotating battery part in a direction generally perpendicular to the longitudinal axis of the spindle; andengaging the sealing feature of the rotating battery part with the forming portion of the tool to transform the profile of the sealing feature from the first cross-sectional shape to a second, different cross-sectional shape. 9. The method of claim 8 wherein engaging the sealing feature with the forming portion includes moving the spindle in a first direction and a second direction, opposite to the first direction while the forming portion of the tool remains in contact with the sealing feature, and wherein the first and second directions are parallel to the longitudinal axis of the spindle. 10. The method of claim 8 wherein the second cross-sectional shape includes an undercut. 11. The method of claim 8 wherein the rotating occurs a predetermined number of times. 12. The method of claim 8 wherein the tool, the forming portion, and the axis of rotation are a first tool, a first forming portion, and a first axis of rotation, respectively, wherein moving the first tool toward the rotating battery part includes moving the first axis of rotation in a first direction, and wherein the method further comprises: moving a second tool having a second forming portion toward the rotating battery part, wherein the second tool has a second axis of rotation, and wherein moving the second tool includes moving the second axis of rotation in a second direction generally opposite the first direction; andengaging the sealing feature of the rotating battery part with the second forming portion of the second tool to further transform the profile of the sealing feature. 13. The method of claim 12 wherein the first and second forming portions have different cross-sectional shapes.
