采用化学粘结Fe +SiC磁性磨料对 30CrMnSiA钢管外圆进行磁力研磨试验 ,研究了磨料成分、粒度以及研磨时间与研磨后表面粗糙度的关系。试验所得到的研磨表面粗糙度达到了Ra0 .0 5 μm
The chemical bonding of Fe + SiC magnetic abrasive was used to test the cylindrical grinding of 30CrMnSiA steel tube. The relationship between abrasive composition, particle size, grinding time and surface roughness was studied. The test results in a polished surface roughness of Ra0.050 μm
