Abstract
An outside diameter finishing tool (10) has an outer shell (16) and an inner annular abrasive layer (22) for precision finishing the outer surfaces of generally cylindrical workpieces. The inner layer (22) of the tool (10) is made of superabrasives and defines the cutting size of the tool (10). The inner layer (22) cuts simultaneously around the full periphery of a cylindrical workpiece rotated within the tool (10). A slot (14) is provided through the tool (10) to allow for radial adjustment of the cutting size of the tool (10).
Claims37
A precision surface finishing tool for uniform micron-tolerance polishing of an outer diameter of a workpiece comprising:
- an outer shell having an outside surface and an inside surface, said outer shell containing a longitudinal slot therethrough;
- and
- an inner annular superabrasive layer fixedly secured to the inside surface of the shell by an adhesive resin layer, the inner layer defining a cavity having at least one open end for receiving the workpiece to be finished.
A precision surface finishing tool for uniform micron-tolerance polishing of an outer diameter of a workpiece comprising:
- an outer shell having an outside surface and an inside surface, said outer shell containing a longitudinal slot therethrough;
- and
- an inner annular abrasive layer carried within the shell on an adhesive resin layer, the inner layer defining a cavity having at least one open end to receive a workpiece to be finished.
A precision surface finishing tool for uniform micron-tolerance polishing of an outer diameter of a workpiece comprising:
- an outer shell having an outside surface and an inside surface, said outer shell containing a longitudinal slot therethrough;
- and
- an inner annular abrasive layer carried on the inside surface, the inner layer defining a cavity having an outwardly tapered section having one end in communication with a cylindrical section, the outwardly tapered section having another end defining an opening in the tool, to receive a workpiece to be finished.
A precision surface finishing tool for uniform micron-tolerance polishing of an outer diameter of a workpiece comprising:
- an outer shell having an outside surface and an inside surface, said outer shell containing a longitudinal slot therethrough;
- and
- an inner annular superabrasive layer fixedly secured to the inside surface of the shell by an adhesive resin layer, the inner layer defining a cavity having at least one open end for receiving the workpiece to be finished;
- and means for holding either of said tool and workpiece, said holding means being adapted to guide said held tool or workpiece into more precise alignment with said other piece.
A precision surface finishing tool for uniform micron-tolerance polishing of an outer diameter of a workpiece comprising:
- a sleeve having an inner surface and an outer surface, the inner surface being formed by electroplating abrasive material onto the sleeve to form an abrasive layer which defines a cylindrical opening in the tool to receive a workpiece to be finished, said sleeve containing a longitudinal slot therethrough for allowing expansion and contraction of the tool to radially adjust the inner surface of the tool.
A precision surface finishing tool for uniform micron-tolerance polishing of an outer diameter of a workpiece, said tool comprising:
- an outer shell having an outside surface and an inside surface;
- and
- an inner annular abrasive layer being disposed within the outer shell, the inner layer defining a cavity having at least one open end for receiving the workpiece to be finished,
- wherein said outer shell and said inner annular abrasive layer have a longitudinal adjustment slot extending therethrough, and
- wherein said outside surface of said outer shell has at least one longitudinal outer slot to allow for radial adjustment of said inner abrasive layer.
