Claims15
Apparatus for effecting high tolerance finishing of a workpiece surface comprising:
- a mounting member including attachment means suitable for attachment to rotary drive apparatus for rotation of the mounting member about a first axis;
- at least one resilient abrasive finishing element rotataby mounted on said mounting member for motion relative to said workpiece surface in a plane perpendicular to said first axis;
- bearing means supporting said at least one finishing element on said mounting member for free rotation of said at least one finishing element relative to said mounting member;
- and
- means for collecting particulate matter generated during a finishing operation from wear of said finishing element mounted on said mounting member;
- said at least one resilient abrasive finishing element comprising an annular body of uniformly intermixed resilient and abrasive substances.
