摘要:
A system for polishing a cylindrical lip-seal surface includes a spin platter, a polisher having an abrasive surface, and a fixture. The spin platter rotates about a rotation axis to spin a workpiece, shaped as a hollow cylinder, about a cylinder axis of the hollow cylinder. The fixture holds the polisher against an outward-facing cylindrical surface of the hollow cylinder to polish the cylindrical surface with the abrasive surface while the workpiece is spun by the spin platter. A method for polishing a cylindrical lip-seal surface includes spinning, with a spin platter, a workpiece shaped as a hollow cylinder about a first cylinder axis of the cylinder. The method also includes holding, during the spinning, a polisher having an abrasive surface against an outward-facing cylindrical surface of the hollow cylinder to polish the cylindrical surface.
