PROBLEM TO BE SOLVED: To shorten a grinding time by continuously exerting a large grinding force to the place to be ground such as burrs or irregularity on the outer peripheral surface of the object to be ground, and also to shorten the working time required for smoothing the object to be ground. SOLUTION: The grinding plate oscillating type belt grinding machine is equipped with a grinding plate oscillating mechanism 37 which provides a lot of linear projection rows by extending to the inclined direction with respect to the traveling direction of the grinding belt 11 on a grinding belt receiving surface forming side of the grinding plate 27, disperses and disposes the projection parts 33 on the grinding belt receiving surface forming side, forms the grinding belt receiving surface 28 by the top surface 32 of the projection parts 33, oscillates the grinding plate 27, and continuously reciprocates the grinding belt receiving surface 28 to the direction perpendicular to the traveling direction of the grinding belt 11. The belt grinding machine is equipped with a belt oscillating mechanism 47 which continuously reciprocates the grinding belt 11 to the direction perpendicular to the traveling direction.
