Polishing tool for miniature precision part

The grinding tool comprises a grinding table, grinding plates and a fixing part, a sliding groove allowing the miniature precise part to slide is formed in the grinding table, and the grinding plates are fixedly connected into the sliding groove and located on the two sides of the sliding path of the miniature precise part. The distance between the grinding plates on the two sides of the miniature precision part is gradually reduced to the standard width of the miniature precision part in the advancing direction of the miniature precision part, one end of the fixing part is fixedly connected with the grinding table, and the other end of the fixing part abuts against the grinding plates or is fixedly connected with the grinding plates. The method has the effect of improving the yield of the miniature precision parts. 本申请涉及一种微型精密件的打磨工装，其包括打磨台、磨削板以及固定件，打磨台上设有供微型精密件滑过的滑移槽，磨削板固定连接在滑移槽内且位于微型精密件滑移路径的两侧，微型精密件两侧磨削板之间的距离尺寸沿微型精密件前进方向渐缩至微型精密件的标准宽度尺寸，固定件的一端与打磨台固定连接，其另一端抵紧磨削板或者与磨削板固定连接。本申请具有提升微型精密件良品率的效果。
