文章介绍了超硬材料复合磨盘在磨削铁基粉末冶金方面的应用。通过与国外磨盘磨削性能对比，所研制的复合磨盘可以对铁基粉末冶金工件进行精密研磨。另外，通过研究发现，磨盘磨料粒度对磨削效率、磨削质量以及磨盘消耗都有较大影响，其中对磨削效率影响最大。在满足磨削质量的情况下，应该选择粗粒度磨料。修整环的参数，对磨盘磨削性能也有重要影响。经过合理选择和调整磨料粒度，制作的复合磨盘磨削铁基粉末冶金工件效率高、工件表面精度高，具有较好的市场推广价值。

The applications of ultra-hard grinding disc are introduced in this paper in grind-ing iron-based powder metallurgy.Compared with grinding performance of foreign prod-uct,the grinding disc can precision grinding the iron-based powder metallurgy.In addi-tion,it is found that the millstone grit size has a greater impact on grinding efficiency, quality and millstone consumption,of which the greatest impact on the grinding efficien-cy.At the case of satisfying grinding quality,we should choose a coarse-grained abrasive. The parameters of dressing wheel can also great impact on the efficiency of grinding disc. Through the optimizing test of reasonable choice and adjustment of abrasive particle size, the grinding disc can grind iron-based powder metallurgy work piece with high efficiency and high precision surface,and has a good marketing value.
