本研究采用磁力研磨与电解相结合的方法，研究了管材内部光整加工过程中的光整加工特性。电解产生一层氧化铝薄膜，加速去除表面的初始发际线形态。随后，用MAF去除薄膜。该工艺在较短的时间内显著降低了表面粗糙度。重点研究了在MAF加工过程中，加工条件，如杆管间隙、铁粉粒度和研磨性组合以及加工时间对表面形貌的影响。测量了表面粗糙度，并记录了加工后表面的图像，以研究表面形貌的变化。长时间的电解整理会加深氧化膜和凹坑，从而对表面产生不利影响。这一证据表明，凹坑残差有助于较高的表面粗糙度值。
In this research, the finishing characteristics in a tube's internal finishing process using the method of magnetic abrasive finishing (MAF) combined with electrolysis has been studied. Electrolysis produces an aluminium oxide film that accelerates the removal of the initial hairline morphology on the surface. Subsequently, the film is removed with MAF. This process significantly minimises the surface roughness in a reduced time. The way the finishing conditions, such as the pole–pipe gap, iron particle size and abrasiveness combinations, and processing time affected the surface morphology in the MAF machining process has been particularly examined. The surface roughness was measured and images of the finished surfaces were recorded to study the morphology changes. Prolonged electrolysis finishing was seen to deepen the oxidation film and pits, which adversely affects the surface. This evidence suggests that the pit residuals contribute to higher surface roughness values.
