Abstract
An improved sanding wheel configured to rotate axially for sanding or polishing milled contours that will provide sharp edges and corners in the workpiece. The preferred sanding wheel has a cylindrical body with a plurality of segments extending radially from the body that have vertical, horizontal, angled, convex, or concave faces that match the contour of the milled workpiece. The faces of each of the segments have abrasive that may have a generally horizontal or vertical lay and the segments may be alternated. In one embodiment, equal numbers of segments with horizontal, vertical arcuate or angular faced abrasive surfaces are provided.
Claims31
A sanding head, comprising:
- a cylindrical body configured for axial rotation;
- a plurality of segments radiating circumferentially from a sidewall of said cylindrical body;
- a plurality of sanding surfaces at a distal edge of said segments;
- and
- an abrasive layer disposed on said sanding surfaces;
- wherein each of said plurality of segments has at least one horizontal sanding surface and at least one adjacent vertical sanding surface;
- wherein said abrasive layer disposed on said horizontal sanding surface of a first plurality of shaped segments has a grit size that is larger than a grit size of said abrasive layer disposed on said horizontal sanding surfaces of a second plurality of shaped segments;
- and
- wherein said first shaped segments and said second shaped segments alternate around the circumference of said cylindrical body.
