磁性研磨法去除管道内部毛刺在管道上钻孔后会产生刺，而一般的去毛刺工具难以进入细长管或弯曲管，只得手工去除。作者研究了一种磁性研磨去毛刺新技术，本文将介绍其原理及特点。图１是传统的磁性研磨法立体与平面原理图。将含铁粉磨料装入管内，受到两个电磁铁的磁力吸... Magnetic grinding method to remove internal pipe burr will produce thorns in the pipe after drilling, and general deburring tools difficult to enter the slender pipe or curved pipe, only to be manually removed. The authors studied a new technology for magnetic deburring, this article describes its principles and features. Figure 1 is a traditional magnetic grinding method of three-dimensional and planar schematic. The iron powder abrasive loaded tube, by the two electromagnets magnetic suction ...
