“…The unbonded type of magnetic abrasive comprises ferrous particles and fine abrasive particles (e.g., aluminum oxide (Al 2 O 3 ), silicon carbide (SiC), cubic boron nitride (CBN), carbon nanotubes (CNTs), etc.) [ 14 ]. Heng et al [ 15 ] improved the surface roughness of Mg alloy bars using the unbonded type of magnetic abrasives with CNT abrasives, and compared it to the unbonded type of magnetic abrasives without CNT abrasives.…”

This study proposes a new wire magnetic abrasive finishing (WMAF) process for finishing 316L SUS wire using ecological magnetic abrasive tools. 316L SUS wire is a biomaterial that is generally used in medical applications (e.g., coronary stent, orthodontics, and implantation). In medical applications of this material, a smooth surface is commonly required. Therefore, a new WMAF process using ecological magnetic abrasive tools was developed to improve the surface quality and physical properties of this biomaterial. In this study, the WMAF process of 316L SUS wire is separated into two finishing processes: (i) WMAF with ecological magnetic abrasive tools, and (ii) WMAF with industrial magnetic abrasive tools. The ecological magnetic abrasive tools consist of cuttlefish bone abrasives, olive oil, electrolytic iron powder, and diamond abrasive paste. The finishing characteristics of the two types of abrasive tools were also explored for different input parameters (i.e., vibrating magnetic field and rotating magnetic field). The results show that ecological magnetic abrasive tools can improve the initial surface roughness of 316L SUS wire from 0.23 µm to 0.06 µm. It can be concluded that ecological magnetic abrasive tools can replace industrial magnetic abrasive tools.

“…8 The atomizing rapid solidification magnetic abrasives developed by the research group have a large number of static effective cutting edges, exhibiting excellent performance. The abrasive particles are evenly distributed on the iron matrix, which makes the magnetic abrasives have good grinding performance when grinding all kinds of ceramic, 316 Stainless steel, 9 Ti6Al4V, Inconel 718, 10,11 cast iron materials, 12 organic glass, and metal materials. Compared with the magnetic abrasives prepared by the sintering method, the chemical composition of atomized powder particles is the same and uniform, and does not exist segregation phenomenon.…”

To improve the surface roughness of Copper-Nickel alloy (Cu-Ni alloy) and explore the effect of magnetic abrasive finishing on the surface hardness and hydrophobicity of Cu-Ni alloy, the spherical magnetic abrasives are prepared by atomizing rapid solidification method. The effects of various process parameters on the surface quality of Cu-Ni alloy are explored, and the optimal process parameters of magnetic abrasive finishing of Cu-Ni alloy are obtained. The Neodymium-Iron-Boron permanent magnetic pole is used to grind the workpiece with XK7136C CNC milling machine. Three dimensional profilometer, metallographic microscope, and digital Vickers hardness tester are used to analyze the surface morphology of the workpiece. The hydrophilicity and hydrophobicity of the workpiece are measured by a contact angle goniometer. The effects of spindle speed, feeding rate, processing distance, and abrasive filling amount on the surface quality of workpiece are investigated by the orthogonal experiment and the single factor test. When the spindle speed is 1300 r/min, the feeding rate is 13 mm/min, the processing distance is 1.2 mm, and the abrasive filling amount is 2.0 g, the surface roughness of Cu-Ni alloy decreases from 0.212 to 0.023 μm and the hardness increases from 114 to 119.8 hv. Finally, the mirror effect of Cu-Ni alloy is achieved. When the optimal test parameters are used, the surface roughness of Cu-Ni alloy can be effectively reduced in a short time. The surface quality of the workpiece is improved, the surface hardness of the workpiece is affected to a certain extent, and the service life of the workpiece is prolonged.

The article concerns the possibility of the automation and robotization of the process of deburring jet engine components. The paper presents the construction of a laboratory stand enabling the automation of selected production operations of typical low-pressure turbine blades. The work identifies important parameters and results of the technological process related to the removal of burrs that affect the exactness of the process. The results of the analysis of the impact of individual process parameters on the magnitude of forces and moments occurring during deburring were carried out and presented. The results of initial and detailed tests were presented. Based on the results obtained, it was noticed that doubling the rotational speed of the brush results in a linear increase in torque and an increase in the engagement of the detail in the disc brush, leading to a non-linear increase in torque. It has also been shown that with tool wear, the value of the torque generated by the rotating tool decreases. Based on the results of a comparison of manual and automated process and histogram analysis, results from an automated stand are centered more correctly inside of the required radius range. This means that the repeatability of the process is higher for an automated test stand, which is one of the key aspects of large-scale aviation component manufacturing. Additionally, it was confirmed by visual inspection that all burs had been removed correctly—the deburring operation for all tested work pieces was successful. Based on the results obtained, it was proven that introduction of an automated stand can improve working conditions (by the elimination of the progressive fatigue of employees and the possibility for injury) and allows for the elimination of the negative impact of the machining process on workers. Further areas in which the optimization of the process parameters of the edge deburring can be developed in order to reduce unit costs have also been indicated.
