摘要/Abstract

摘要：

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29nm,与非磁控砂轮相比，表面质量得到了明显提高。

关键词: 环形磁场, 磁场仿真, 微粉砂轮, 磨粒规则分布

Abstract:

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

Key words: ringmagnetic filed, simulation of magnetic field, micro powder grinding wheel, abrasive particle arrange regularly
