20140115798 | PROCESSING BRUSH AND BRUSH-TYPE PROCESSING DEVICE - In a brush-type processing device, a base portion of a processing brush is fixed to a reciprocating rotating shaft provided to a drive source. A brush portion extends from the base portion to one side along the radius of the reciprocating rotating shaft. When the reciprocating rotating shaft reciprocatingly rotates, a plurality of brush bristles of the brush portion reciprocatingly oscillates in a circumferential direction of the reciprocating rotating shaft. Accordingly, an object to be removed on a processed surface can be scraped off by allowing distal ends of the brush bristles to be pressed against the processed surface. In this case, the distal ends of the brush bristles that reciprocatingly oscillate repeatedly collide with the object to be removed from both sides in a reciprocating oscillation direction, thereby making it possible to effectively remove the object to be removed. | 05-01-2014 |
