The results of the study of using the end-type heads based on permanent magnets for polishing flat surfaces of ferromagnetic parts on standard metal-working equipment are presented in the work. The possibility of a highly efficient achievement of the roughness of flat surfaces up to Ra < 0.05 μm with the initial Ra > 1–2 μm with removing of the heredity of the machining in the form of microwaves obtained in the face milling operation was shown. Based on the results of the analysis of the process of dispergation of the material was analyzed the influence of the magnetic field gradient the intensity of the magneto-abrasive machining of flat ferromagnetic surfaces by heads, which form a magneto-abrasive tool in the shape of a “brush” and “half of torus”. The influence of technological process parameters: the rotation speed of the working heads, the sizes of the working gap, the technological feed on the character of the change in the microgeometry of the machined surface were investigated. The machining conditions, under which occur the preferential machining of micro peaks or micro valleys on a rough surface, were identified. It was determined that the rational conditions of the magneto-abrasive machining of flat ferromagnetic surfaces are: the rotation speed of the working heads 900 rpm, the gap size between the machined surface and the working surface of the head 2.5–4.0 mm and the working feed 10–15 mm/min. Keywords: finishing, roughness, polishing, permanent magnet, magneto-abrasive tool.

Investigations of the magneto-abrasive machining (MAM) process of ferromagnetic flat surfaces by three types of end heads were carried out. The nature of the change in the magnitude of the magnetic induction in the working zones was determined. The influence of technological parameters of the machining process was investigated, such as the feed rate of the working heads, the frequency of their rotation about their axis, the size of the working gaps on the change in the parameters of the microroughness of the machined surfaces - Sa, Sp, Sv, the frequency distribution of heights microroughness and size of the supporting surface of the profile. It was shown that the level of roughness achieved after MAM is practically the same and does not exceed, under rational conditions of the MAM process, the values Sa = 0.05-0.07 μm, Sp = 0.2 μm and Sv = 0.39 μm with the only difference that the MAM process by the heads of the "brush-half of torus" type are being realized with increased productivity, especially in terms of reducing waviness and individual elements of the heredity of machining, determined by such factors as depth and feed rate during milling. The kinetics of the formation of a microprofile of surfaces is shown under various technological conditions of the MAM process.

“…Magnetic abrasive finishing is used in different kinematic variations for machining flat surfaces [1][2][3][4][5][6][7][8][9][10][11], shafts [12][13][14], thin-walled tubes [15][16][17][18][19], wires [20,21], cutting tools [22][23][24] and freeform surfaces [25][26][27]. However, this usually requires separate equipment, which increases the time and costs involved.…”

Magnetic abrasive finishing (MAF) shows a high potential for use on computerized numerical control (CNC) machine tools as a standard tool to polish workpieces directly after the milling process. This paper presents a new MAF tool with a single, large permanent magnet and a novel top cover structure for finishing the plain ferromagnetic workpieces. The top cover structure of the MAF tool, combined with an optimized working gap, ensures the effect of mechanical powder compaction, which leads to a significant increase in process capability and surface roughness reduction. The influence of the process parameters such as feed rate, equivalent cutting speed, working gap (including for three grain sizes) and the gap to the magnet was investigated. In addition, the influence of the initial surface after face milling, end milling, ball end milling and grinding on the surface quality after MAF was investigated. Furthermore, three typical surfaces after milling and MAF were analyzed. By magnetic abrasive finishing, a significant surface quality improvement of the initial milled surfaces to roughness values up to Ra = 0.02 µm and Rz = 0.12 µm in one processing step could be achieved.
