Trapezoidal grinding disc

The utility model belongs to the technical field of grinding tools, and provides a trapezoidal grinding disc which comprises a disc body and a plurality of grinding blocks, the grinding blocks are fixedly arranged on the disc body, the longitudinal section of each grinding block is trapezoidal, the width of each grinding block is gradually increased from the center of the disc body to the edge of the disc body, and the grinding blocks are arranged in a circumferential array mode with the center of the disc body as the circle center. The center of the disc body is located outside the extension line of the center line of the grinding block. By means of the technical scheme, the problems that an existing grinding disc is small in grinding area and poor in grinding effect are solved. 本实用新型属于磨具技术领域，提出了一种梯形磨盘，包括盘体和磨块，磨块为多个，均固定设置在盘体上，磨块的纵截面为梯形，且磨块的宽度从盘体的中心到边缘逐渐变大，多个磨块以盘体的中心为圆心呈圆周阵列设置，且盘体的中心位于磨块的中心线的延长线外。通过上述技术方案，解决了现有磨盘的磨削面积小、磨削效果差的问题。
