提出了一种利用磁性加工工具对厚壁管件内表面进行磁力研磨光整加工的方法。实践证明，该工艺对厚壁管的精整加工是有效的，在提高粗糙度的同时，还能提高圆度。但提高圆度的机理尚不清楚，有必要从理论上进行研究。首先，利用假想中心法测量圆度的原理，推导出圆度曲线的表达式，得到圆度曲线的傅里叶级数展开式。分析了圆度改善的影响因素。其次，对SUS 304不锈钢管进行了实验研究。通过对机理分析结果和实验结果的验证，得出结论：采用磁性加工工具的内磁性研磨加工工艺对提高壁厚为10 ~ 30 mm的厚壁管材的圆度是有效的，且随着管材壁厚的增加，圆度的提高幅度减小。
An internal magnetic abrasive finishing process using a magnetic machining tool was proposed for finishing the internal surface of the thick tubes. It has been proved that this process is effective for finishing thick tubes, and it can improve the roundness while improving the roughness. However, the mechanism of improving the roundness is not clear, so it is necessary to study it theoretically. In this research, firstly, the roundness curve expression was derived using the principle of roundness measurement by the assumed center method, and the expression of roundness curve expanded by Fourier series was obtained. The influencing factors of roundness improvement were then analyzed. Secondly, the experiments were carried out on SUS304 stainless steel tubes. By confirming the mechanism analysis results and the experimental results, it was concluded that the internal magnetic abrasive finishing process using the magnetic machining tool was effective for improving the roundness of the thick tubes whose thickness is from 10 mm to 30 mm. As the thickness of the tube increased, the improvement in roundness decreased.
