<P>PROBLEM TO BE SOLVED: To provide a belt grinder appropriate for increase and decrease in size thereof, which continuously exhibits a large grinding force against ground parts such as burrs and irregular parts on an outer peripheral surface of a ground material to shorten a grinding time period, improve a grinding efficiency and shorten a working time period required for smoothing the ground material. <P>SOLUTION: A belt 23 with multiple projection parts is interposed between a fixed surface plate 17 and a grinding belt 18, and they are overlapped with each other in three layers. When forming a belt with multiple projection parts as the belt 23 with the multiple projection parts, multiple linear shaped projection parts 22 are provided to extend in a direction inclined with respect to the traveling direction of a belt body 24 on a grinding belt receiver surface-forming side of the belt body 24, and these projection parts 22 are arranged to be dispersed on the grinding belt receiver surface-forming side so that top surfaces of the projection parts 22 form the grinding belt receiver surface. The traveling directions of both the belts 18 and 23 are set in the same direction, and the traveling speeds of both the belts 18 and 23 are set at the nearly same speeds. <P>COPYRIGHT: (C)2013,JPO&INPIT |
