Abstract: Nano-lubricant minimum quantity lubrication (NMQL) is an eco-friendly precision technology used for grinding challenging aerospace materials. However, its film-forming ability and anti-friction performance in high-speed and high-pressure grinding zones cannot satisfy the processing requirements. To address this limitation, a novel method using magnetic traction nano-lubricant was investigated. By applying an external magnetic field, a gradient magnetic field is formed on the surface of the grinding wheel to absorb the magnetic lubricant and improve the infiltration performance. A permanent magnet was used to magnetize the grinding wheel matrix, thereby directing the magnetic flux lines and guiding the distribution of the magnetic field through the grinding wheel. Hence, the magnetic field distribution was numerically simulated by adjusting the distribution, geometric position, and parameters of the permanent magnet. In type I (wherein there is repulsion between the N-S poles on the left and right), a uniform and strong magnetic field can be generated when L=6-16 mm, β=0°-30°, and H is suitably increased. This set up can achieve a maximum magnetic field intensity of 1.1×105 A/m. Furthermore, the impact of the geometrical parameters (L, H, and β) of the magnetic-assisted device on the grindability of Ti-6Al-4V was examined using an orthogonal experiment. The optimum parameters for the permanent magnet arrangement and the geometric position were L=12 mm, H=10 mm, and β=0°, thereby resulting in a smoother workpiece with fewer defects.
