Abstract:

A deburring method is presented wherein a cylindrical brush rotationally contacts the workpiece. The brush includes a mandrel having a central axle to provide support during use. To the mandrel is attached a multiplicity of long bristles. Each bristle is flexible and has impregnated therein a plurality of abrasive particles. The population density of the bristles on the brush is such that the outwardly extending ends can readily flex both in the plane of rotation and sidewise along the lengthwise dimension of the brush. Setting the brush so that the bristle ends overlap the surface of the workpiece being deburred, each bristle makes a slapping contact therewith. This results in one to two inches of each bristle being dragged endwise across the surface of the workpiece. The endwise movement of each bristle causes the abrasive particles imbedded therein to abrade the sharp edges of the workpiece. An automatic conveyor may be used to feed workpiece stock past the rotating brush at a predetermined rate.
