Grinding disc and horizontal fine grinding machine with same

The grinding disc is provided with a shaft hole and a hollow hole, the axis of the shaft hole coincides with the axis of the grinding disc, the hollow hole is provided with a first wall face and a second wall face, and the first wall face and the second wall face are oppositely arranged in the circumferential direction of the grinding disc at intervals. In the cross section orthogonal to the axial direction of the grinding disc, the projection of the first wall face and the projection of the second wall face are both arc-shaped, and the curvature radius of the projection of the first wall face is larger than that of the projection of the second wall face. The grinding disc is good in grinding effect and high in production efficiency. 本发明公开了一种研磨盘和具有其的卧式细磨机，所述研磨盘上开设有轴孔和镂空孔，所述轴孔的轴线与所述研磨盘的轴线重合，所述镂空孔具有第一壁面和第二壁面，所述第一壁面和所述第二壁面沿所述研磨盘的周向相对且间隔布置，在正交于所述研磨盘轴向的横截面内，所述第一壁面的投影和所述第二壁面的投影均为弧形，且所述第一壁面的投影的曲率半径大于所述第二壁面的投影的曲率半径。本发明的研磨盘的研磨效果较好，生产效率较高。
