A new magnetic polishing liquid (MPL) for contact force-free surface finishing II: Detailed performance in metal surface finishing

Magnetic polishing liquid (MPL), a mixture of MF (magnetic fluid), MRF (magnetorheological fluid), abrasive particles and cellulose, is a type of smart material proposed for surface finishing by the authors. Its fundamental performance in non-contact surface finishing was experimentally investigated with respect to the influences of the magnetic field strength and the gap between the working surface and the polishing pad surface on work surface quality indicators such as surface roughness and topography. The results showed that a stronger magnetic field gives a better surface quality, and that an appropriate gap is important in increasing the polishing efficiency.
