Magnetic field assisted polishing is an unconventional polishing method which is capable of generating fine finish on components without any sub-surface damage. This process is suitable not only for polishing external and internal surfaces also for complex shaped components. Magnetic field assisted polishing can be classified into two types. They are Magnetic Abrasive Machining (MAM) and Semi Magnetic Abrasive Machining (SMAM). In MAM, abrasives such as Aluminium Oxide (Al2O3) and Silicon Carbide (SiC) are conglomerated with ferromagnetic iron particles of definite ratio. This conglomerate is magnetised by external field and used as the tool for polishing pre-machined surfaces. Another approach is to have magnetic abrasive particles, specially made for this purpose. In case of semi magnetic abrasive machining, abrasive grains such as Al2O3 and SiC possessing certain magnetic properties are directly magnetised by external magnetic field and are used as polishing tool. These abrasive particles are coated with iron particles when they are milled and hence exhibit magnetic properties.
