Abstract
A workpiece having a planar face the workpiece is rotated about a workpiece axis substantially perpendicular to the planar workpiece face, and a grinding disk centered on a disk axis is rotated about the disk axis. The disk has an annular planar disk face perpendicular to and centered on the disk axis and an annular frustoconical disk face extending from an edge of the planar disk face, centered on the disk axis, and angled inward from the planar disk face. A portion of the annular face is oriented perpendicular to the workpiece axis and pressed against the planar workpiece face to premachine most of the planar workpiece face. Thereafter the disk is pivoted and oriented parallel the planar workpiece face to finish machine the planar workpiece face with the planar disk face.
