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.
