提出了一种基于磁场作用来实现磨粒规则排布的砂轮制备方法，设计了金刚石微粉砂轮成形装置，并对其磁路及环形磁场分布进行了仿真。观察了环形磁场的分布状况，制作了磁控砂轮，并用制作的磁控砂轮磨削了碳化钨试件。试件表面粗糙度 Ra达到了29 nm ，与非磁控砂轮相比，表面质量得到了明显提高。

A forming method of grinding wheel was introduced based on ring-magnetic field control to make abrasive particle arrange regularly .A forming device of micro diamond powder wheel was de-signed .Its magnetic circuit and ring-magnetic field distribution were simulated .After observing the magnetic field distribution ,the grinding wheels were produced in the forming device and tungsten car-bide test specimens were ground .The surface roughness value of test specimens is as 29 nm .Compared with grinding wheels non magnetic field control forming ,the surface quality is improved obviously .
