Cylinder liner microfinishing apparatus and method

摘要

An apparatus for microfinishing an interior cylindrical surface. The apparatus includes a mechanism which holds and rotates the workpiece about an axis. A tool, having radially directed work areas, is positioned within the workpiece and causes a strip of abrasive sheet material, positioned over the work areas, to engage the rotating workpiece. With the abrasive sheet material engaging the rotating workpiece, the tool is axially oscillated.
