Due to the smal surface of the thin and tal workpiece which is in contact with the table.it is difficult to achieve the reli￣able positioning before grinding and clamping and clamp it on the machine talbe. To solve this trouble problem,this article de￣signs and manufactures an auxiliary positioning plate to improve the processing efficiency and ensure the positioning acuracay of the parts.%针对薄而高的零件因与磨床工作台接触面积小，无法实现磨削前的可靠定位与夹紧问题，设计并制造了一种简单且实用的辅助定位板，既解决了实际难题，又大大提高加工了效率，并保证了零件的相互位置精度要求。
