“…Due to the probe's constructional limitations, the measurement on the Z axis was performed at an initial distance of 6 mm from the surface of the magnets and then in 3 mm increments (Figure 6). The next stage of the study was a design of experiment for the ranges of machining parameters selected on the basis of the literature [24]. We determined three parameters with the greatest expected machining results.…”

In this article, we present a numerical model of a magnetic abrasive finishing station, which was analyzed using the finite element method (FEM). The obtained results were compared with the real values measured on an experimental station of our own design. The prepared station had the option of adjusting the magnetic flux density inside the machining gap, the width of which could be changed from 10 to 30 mm. The maximum value of the magnetic flux density inside the air gap was 0.8 T. The real distribution of magnetic flux density in the finishing area was also analyzed. A design of experiment was carried out with the following variables: abrasive grain concentration, width of the machining gap, and process duration. The results are presented in the form of regression equations and characteristics for selected roughness parameters.

“…Currently, MAF has been extensively studied in highly sophisticated industries such as healthcare, communication technology, aerospace, and the military [ 26 , 27 , 28 , 29 , 30 , 31 , 32 ]. MAF has now been applied to polish the inner walls of tubes [ 33 , 34 , 35 , 36 ]; however, few studies have emerged using magnetic abrasives to polish the inner walls of ultra-fine cobalt–chromium alloy cardiovascular stent tubes. This is due to the irregular shape of existing magnetic abrasives, which not only makes loading into ultra-fine long cardiovascular stent tubing difficult, but also makes the depth of cut of the machined surface inconsistent, limiting the improvement of surface quality.…”

In this investigation, spherical Al2O3 magnetic abrasive particles (MAPs) were used to polish the inner surface of ultra-fine long cobalt–chromium alloy cardiovascular stent tubes. The magnetic abrasives were prepared by combining plasma molten metal powder and hard abrasives, and the magnetic abrasives prepared by this new method are characterized by high sphericity, narrow particle size distribution range, long life, and good economic value. Firstly, the spherical Al2O3 magnetic abrasives were prepared by the new method; secondly, the polishing machine for the inner surface of the ultra-fine long cardiovascular stent tubes was developed; finally, the influence laws of spindle speed, magnetic pole speed, MAP filling quantities, the magnetic pole gap on the surface roughness (Ra), and the removal thickness (RT) of tubes were investigated. The results showed that the prepared Al2O3 magnetic abrasives were spherical in shape, and their superficial layer was tightly bound with Al2O3 hard abrasives with sharp cutting; the use of spherical Al2O3 magnetic abrasives could achieve the polishing of the inner surface of ultra-fine cobalt–chromium alloy cardiovascular bracket tubes, and after processing, the inner surface roughness (Ra) of the tubes decreased from 0.337 µm to 0.09 µm and had an RT of 5.106 µm.
