The Development of Magnetic-abrasive Finishing and Its Equipment by Applying a Rotating Magnetic Field

This paper describes the magnetic-abrasive finishing process, and its trial equipment, in which a cylindrical workpiece is finished with the assistance of a rotating magnetic field using mechanical bonded magnetic-abrasives made of both iron and alumina particles. From the experimental results, it is found that the finishing efficiency is improved and the finished surface roughness vale is a little large in the case of the rotating magnetic field compared with the stationary magnetic field. In this report, which combines the rotating magnetic field with the stationary magnetic field, a new efficient finishing process is developed and confirmed by experiments.
