Automated polisher for cylindrical surfaces

摘要

An automated polisher for cylindrical surfaces. A cylindrical workpiece is rotated about its longitudinal axis. A pad is urged against the inside of the workpiece as it is turned. The pad is quickly moved in a small circle or ellipse or in a short reciprocating motion. The pad is also moved longitudinally along the length of the workpiece so the center of quick pad movement traces a helix on the inner surface of the workpiece. The speed of movement of the center of quick pad movement is controlled as a function of the position of the pad relative to the workpiece so that a controlled polishing occurs.
