摘要：
When the inner surface of the alloy tube is polished by magnetic abrasive finishing, the auxiliary magnetic pole is usually added in the cavity to improve the magnetic induction intensity in the unit space, thus improving the efficiency. However, after the auxiliary magnetic pole is added, the rigidity of the magnetic particle brush is improved, so that the trajectory of the single magnetic abrasive particle is too single, and a deep scratch is easy to appear on the inner surface. In order to solve this problem, a radial rotation motion was put forward to assist the auxiliary magnetic pole. The influence of the motion trajectory of a single magnetic abrasive on the surface quality was analyzed, and a precise polishing test was made on the inner surface of the titanium alloy tube. At a speed of the tube of 1 000 r/min, an auxiliary pole speed of 1 800 r/min, an average particle size of 250 μm, the polishing effect is the best. After finishing for 50 min, the surface roughness value was reduced to about 0.11 μm, the material removal amount was up to 850 mg, and the surface quality was improved obviously. © 2018, Science Press.
